Page 3: Introduction
Introduction Overview The PLC-16.PCI provides 8 Form C relays that can switch and carry 2A loads making it suitable for latching power, data or other electronic signals for control applications. 8 optically isolated inputs are also provided to allow monitoring of off board switch closures, relays or for any other general purpose monitoring needs. The PLC-16.PCI is optimized for 24V DC/AC usage. -
Page 4: Installation
Do not install the Adapter in the machine until the software has been fully installed. 1. Start Windows. 2. Insert the Sealevel Systems CD in to your CD drive. 3. If ‘Auto-Start’ is enabled for this drive the software will automatically launch. Otherwise, point your browser to the ‘Index.htm’... -

4. Gently insert the PCI adapter into the slot. Make sure that the adapter is seated properly. 5. Replace the screw. (This is required to ensure FCC Part 15 compliance.) 6. Install cable (CA165). 7. Replace the cover. 8. Connect the power cord. Installation is finished. Sealevel Systems PLC-16.PCI Page 3... -
Page 6: Technical Description
Technical Description The PLC-16.PCI provides two parallel input/output (I/O) ports. The ports are organized as ports A, B, C, and D. Port A is an input port interfaced to optically isolated inputs, while port C is the relay output port. -

Turn on Voltage = diode drop + (turn on current) x (resistance) 1.1 + (.003) x R Maximum voltage = square root of (resistor value) The input circuits are not for monitoring 120-volt AC circuits. Sealevel Systems PLC-16.PCI Page 5... -
Page 8: Output Port (Relay)
Technical Description Output Port (Relay) The PLC-16.PCI provides 8 Form C (SPDT) Electro-mechanical relays. These relays have three connections; Normally Open (NO), Normally Closed (NC) and a Common. The relays are all de-energized at power-on. Data to the relays is latched by a write to the base+2 address. On/off status of the relays can be read back by a read at the base+2 address. -
Page 9: Port Pin Assignments
Technical Description Port Pin Assignments The PLC-16.PCI has several different cable and terminal block options. The card itself has a high-density 44-pin connector (HD44), unlike many competitive products. This allows both poles (NO/NC) of the Form C relay to be accessed as well as each input of the optically isolated input circuit to be represented as a unique pin on the connector. -
Page 10: Optional Cable Ca184 Pin Assignments
In our continuing effort to make our products more easily integrated into systems that may have previously used our I/O interface products, the CA184 was created. This cable mimics several of the pin-out options found on Sealevel’s PCI and ISA legacy products and provides a direct connection to Sealevel’s TB02, 37 pin Terminal Block. The following table shows the correlation between pins on the CA184 option cable connectors and their specific function. -
Page 11: Optional Terminal Block Kit Kt108
Technical Description Optional Terminal Block Kit KT108 The third option for termination of the PLC-16.PCI is the KT108 Terminal Block Kit, which features the CA185 (HD44 M/F) and the TB08 Terminal Block adapter. This adapter groups the common connections of the PLC-16.PCI into groups of four. -

The relay ports return the ones complement of the value that is currently being used to drive the relays. Writing the Outputs: The output ports are the only ports that can be written. The relays on a standard PLC-16.PCI are normally open. To close a relay a one must be written to the appropriate bit. -

I/O address. 3. Make sure the Sealevel Systems adapter is using a unique IRQ. While the Sealevel Systems adapter does allow the sharing of IRQs, many other adapters (i.e. SCSI adapters & on-board serial ports) do not. The IRQ is typically selected by the BIOS or Operating system. -
