TCW122B-CM is a remote IO module for environmental monitoring and control, designed to work in Ethernet networks. It can be managed by WEB interface, SNMP programs, and user applications.
Remote IO module has two relays with normally open and normally closed contacts. Both relays can be activated locally – from the status of monitored parameters or remotely – by WEB interface, SNMP managers, and HTTP/XML API commands.
TCW122B-CM support 1-Wire interface. Up to two temperature or humidity-temperature sensors can be connected. Along with ambient parameters, two analog voltages and status of two digital inputs can be monitored. For every parameter e-mail and/or SNMP trap for any alarm condition can be sent.
The controller can be used as a standalone device or as a part of data acquisition (SCADA) systems.

*Caution. Teracom's Ethernet Controllers do not include power supply in their packaging and in case of purchase, you will need to order a power supply separately if you do not already have a compatible power supply.
