The 16 point Relay Output Module is versatile, rugged, and easy to use. It will switch a variety of low to medium power loads such as relays, contactors, and lamps. The resistive rating of the module is 2 amps per point at 120/240 VAC or 24 VDC and 0.2 amps per point for 125 VDC. Power to energize the relay coils is supplied by the module and each output is individually fused and suppressed with an RC snubber. LED indicators which display the ON - OFF status of each point on the logic (PLC) side of the circuit are located at the top of the module. Field wiring is made to a removable terminal board and the module is mechanically keyed to ensure correct replacement with a similar module type in the field. I/O references are user configurable without the use of jumpers or DIP switches on the module. Configuration is done using the configuration function of the MS-DOS or Windowsprogramming software running on Windows 95 or Windows NT over Ethernet TCP/IP or through the SNP port. The Programming Software configuration function is installed on the programming device. The programming device can be an IBM XT, AT, PS/2 or compatible Personal Computer.
