Teracom Remote IO module TCW122B-CM


Model Remote IO module TCW122B-CM

VLAN and MAC filters. SNMP v1 support for SNMP manager applications.

Short Description

The 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.

The TCW122B-CM support a 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.


* Reliable IP watchdog;
* Password protected web based configuration and control;
* 1-Wire interface for up to 2 temperature (TST1XX) or temperature/humidity (TSH2xx) sensors;
* 2 relay outputs with NO and NC contacts;
* 2 analog inputs with 0 to 60VDC range;
* 2 digital inputs with “dry contact” or “logic level” mode;
* SNMP v.1 support;
* SNMP trap messages sending under certain conditions;
* VLAN and MAC address filtering;
* Remote FTP firmware update.
