Page 6: Introducing The Irm-48 Reader
1.2 I NSTRUCTIONS FOR The IRM-48 Reader is intended for use in the measurement of Temperature, Humidity, Ambient Temperature, Partial Discharge and Surface Discharge of Low to Medium Voltage air insulated Electrical Equipment. Readers connect Air Interfaces through RF cables for wireless interrogation of SAW temperature sensors and Partial Discharge monitoring, while humidity and ambient temperature sensors are wired to the readers. -
Page 7: Product Overview
The Reader has two labels on the bottom of the unit, a Serial ID label and a compliance label, and one main product label on the top. 2.2.1 Serial ID Label The IRM-48 Serial ID label provides a model number and serial number for the reader. Figure 1: IRM-48 Model Number and Serial ID Label 2.2.2 Compliance Label The compliance label provides product certification information. -

Page 15: Power And Modbus Rtu Connections
Figure 9: Power and Modbus RTU Connections 4.1.1 Power The IRM-48 Reader operates at 48VDC nominal power, but can operate between 24 to 60V DC with a total power consumption of 3.5 W. The following block diagram outlines the recommended power wiring for the IRM-48 Reader with a 2-pole circuit breaker and AC/DC power supply. - Page 16 4.1.1.1 Local versus bussed DC power IntelliSAW recommends the use of a DC power supply in the same low-voltage compartment as the reader. This is the simplest and most flexible option. It is possible to run a DC power bus alongside the RS485 bus, however, this option requires careful consideration of the wire diameter.

Page 17: Communication Connections
Figure 11: RS485 Data Communication Bus Topology 4.2.1.1 Recommended Cabling IntelliSAW recommends the use of shielded cable for the RS485 wiring, providing at least one twisted pair, one single line, and a drain wire, although typical cable has two twisted pair. The twisted pair provides DATA+/- signals to each reader while the single line would be for D-COM, providing a low-impedance return for each reader. - Page 18 The RS485 bus data rate is dependent on the bus cable length and the number of readers on the bus. In industrial environments, slower data communication rates are generally more reliable; IntelliSAW recommends either 19200 baud or 9600 baud for the data rate. Bus length Bus cable length has an impact on the overall data rates which can be achieved.

Please reference the IntelliSAW Sensor Installation Manual for more detail. 5.2 S YSTEM ONFIGURATION The Reader requires system configuration for the associated installed temperature sensors, air interfaces, and humidity sensors. -
Page 21: System Integration
The IRM-48 Reader has one RS485 slave communication connection. The Reader can be connected to a CAM-4 unit or an existing SCADA, DCS, or historian system. All IRM-48 readers are slave devices polled by either a Master CAM-4 unit or SCADA system. -
