- Page 5 Specifications and Warnings Specifications Input Power: 100 - 240VAC, 50 - 60HZ, 10W maximum Operating Temperature: -25C to +50C Enclosure: NEMA-4X Exceeding rated specifications could cause damage to WARNING: equipment and/or personnel. In order to maintain NEMA-4X rating, proper conduits and fittings must be used and installed properly.
- Page 6 General Information - Cellular Dual SIM The cellular Gen-2 RTU includes 2 SIM cards, which allows for the connection between the RTU and the servers via either the Verizon or AT&T cellular networks. Both SIM cards are active at initial installation with their respective carrier, and are field interchangeable.
- Page 7 Figure 1: Replacing SIM Card Cellular Antennas Internal Antenna All cellular units have an internal antenna mounted inside the enclosure. For typical installations, this antenna is sufficient for normal data communications. Omni Directional Antenna For installations where the unit is mounted inside a metal enclosure or a metal building, an external antenna may be needed.
- Page 8 Directional Antenna For cellular installations where signal strength is weak, it is possible to install a directional antenna to boost the signal. High Tide Technologies’ technical support staff have the appropriate tools and software to maximize the effectiveness of this antenna. Figure 3 shows a typical directional antenna.
- Page 9 3.2 General Information - Ethernet High Tide’s Gen-2 Remote Terminal Units have an on-board Registered Jack 45 (RJ-45) port and is shown in Figure 4. When an Ethernet connection is applied, it provides a basis of communication between the hardware in the field and our servers, via the ISP provided by the customer.
- Page 10 Input and Output Connections AC Power Connections Figure 5 shows the AC power input terminals. GREEN is for earth ground, WHITE is for neutral and BLACK is for line voltage. If required, local circuit protections should be provided outside the High Tide enclosure. If AC surge arresters are ordered with the unit, they will be installed at the factory.
- Page 11 The battery connections are color coded. The wire should connect to the ‘+’ battery terminal and the BLACK wire to the ‘-’ battery terminal. Figure 6 shows the battery connections for the Gen-2 RTU. Figure 6: Battery Connections REV: FEB 1 2023...
- Page 12 4.3 Terminal Layout Figure 7 shows all the I/O and power connections on the Gen-2 RTU. Figure 7: Terminal Layout IO Board Versions 4.0 and lower show the DIs labeled DI0-DI3, but are NOTE: actually DI1-DI4 etc. The silkscreen on the board labels the function of each connector which is described briefly below:...
- Page 13 4.4 Discrete Inputs The Gen-2 is equipped with eight discrete inputs. These inputs can be configured in several different ways. All discrete inputs are optically isolated and can be configured via jumpers ‘JP1’ or ‘JP2’ as either sinking or sourcing. JP1 controls DI-1 thru DI-4 and JP2 controls DI-5 thru DI-8.
- Page 14 Dry Contacts and Open Collectors Figure 9 shows a typical dry contact installation. The YELLOW wire would be connected to one side of the dry contact or the open-drain. The BLACK wire would be connected to the other side of the contact or to the ground of the open-drain.
- Page 15 Active Voltage Sources Active voltage inputs are connected the same way as the dry contacts above, with the BLACK wire connected to the common ground and the BLUE wire connected to the active source, however JP1 must be in the GND position for this input mode.
- Page 16 Discrete Input LEDs and Test Button The discrete inputs have LEDs that will allow you to test the current state of the input. The LED for each discrete input is located in front of its respective discrete input. This is especially helpful during the initial installation of the High Tide unit.
- Page 17 4.5 Analog Inputs The Gen-2 is equipped with four analog inputs (AI-1 thru AI-4). The inputs can be configured as: ● 0-5V inputs ● 0-20mA or 4-20mA inputs ● Discrete status inputs The wiring connections for each of these configurations are discussed on the following pages.
- Page 18 24V power supply should be applied to the sensor, and then the return wire is connected to the selected analog input terminal. A ground reference is also required between the external power supply and the Gen-2 RTU. Figure 12 shows the common wiring configuration for this type of input. Figure 12:...
- Page 19 Three-wire current inputs With three-wire current inputs, an external power supply still needs to be applied to the sensor; however, a reference ground is also provided. This type of connection is typically used for sensors that need more than the minimum 4mA to power the sensor.
- Page 20 Self-powered current inputs There is a class of current sources that are self-powered. For these configurations, all that is required is a ground reference and the analog input signal. Figure 14 shows how to connect this type of analog input. The BLACK wire is a reference ground and the YELLOW wire is the output...
- Page 21 Voltage inputs (0-5V) The analog inputs can be used with sensors that produce voltage outputs between 0.0V and 5.0V. The input is tolerant of voltage levels up to 30V but will not report anything greater than 5 volts. When using the analog inputs to sense voltage sources, the WARNING: appropriate 3-W sense resistors, R32 and R33, must be removed.
- Page 22 4.6 Relay Outputs The Gen-2 can be equipped with four relay outputs that can be used to turn on and off local equipment. The optional relay outputs are FORM C type with a Common, NO, and NC contact. The typical application is to use the Common and the NO contacts.
- Page 23 Expansion Board Connections General Information The Gen-2 RTU can be equipped with up to 8 expansion modules. These are connected using a set of cables that connect between the RTU and the first expansion module then additional expansion modules are connected with cables between them creating a daisy chain of multiple expansion modules.
- Page 24 Figure 17 shows a detailed view of the ‘Board ID’ dial on the Digital Input module, but location may vary on other modules types. Figure 17: Gen-2 ‘Board ID’ Dial REV: FEB 1 2023 Page 24 of 32...
- Page 25 The Analog Input Expansion module is shown in Figure 18. Figure 18: Gen-2 Analog Input Expansion Board The connectors are layout to match the Analog input connectors on the RTU except there are 4 blocks on the AI module and there are only two on the main RTU.
- Page 26 Figure 19 shows the Digital I/O expansion module and jumper locations. Figure 19: Gen-2 Digital I/O Expansion Board The connectors, jumpers, and possible wiring configurations on the expansion board are the same as on the main RTU. DI1-DI12 can act as sinking or sourcing inputs whereas DI13-DI16 can only be sinking inputs.
- Page 27 Figure 20: Gen-2 Analog Output Expansion Board The Analog Output module is a new feature for the Gen-2 RTU and is configured for four 4-20mA outputs only. Each of the 4 Analog outputs has three connection terminals ‘Vin’ is the source voltage for the loop and must be supplied from the instrument or an external source.
- Page 28 Modbus Connections General Information The Gen-2 RTU supports MODBUS connections over RS-232, RS-485 or Ethernet. Configuration and set up for MODBUS are handled through Technical Support and are covered with separate documentation. There is one single connector on the RTU, so the customer must select one interface or the other.
- Page 29 Figure 22 shows the MODBUS connector location. For RS-232 mode the ‘TX’ pin is data outgoing from the RTU and the ‘RX’ pin is data incoming from the instrument/PLC. For RS-485 mode the ‘TX’ pin is RS-485(B) and ‘RX’ is RS-485(A). Figure 22: MODBUS Serial Connector The general status LED has colors and blinking patterns that indicate the...
- Page 30 LED. Figure 23: Status LED Location All Gen-2 units are equipped with a Hard Reset Button labeled ‘SW1 NOTE: RESET’ located just below the status LED. This button will cause the RTU to do a full software reset.
