Model: TCW122B-CM


Model Remote I/O module TCW122B-CM

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

Short Description

The TCW122B-CM is a remote I/O module for environmental monitoring and control, designed to work in Ethernet networks. It can be managed by WEB interface, SNMP programs, and user applications.

The Remote I/O 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 supports a 1-Wire interface. Two temperature or humidity-temperature sensors can be connected. 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 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.
