TCW122B-CM - Ethernet Digital IO, Voltage, Temperature, Humidity Alarm and Control

The TCW122B-CM is a multifunctional device for remote monitoring and control over Ethernet. It has 2 digital inputs, 2 relay outputs 2 analogue inputs and can monitor up to 2 "1-wire" based temperature or humidity sensors. Parameters and output relays can be monitored and controlled using a web interface or SNMP protocol. The TCW122B-CM can be configured to send email messages, send SNMP traps and toggle the relay outputs depending on analogue or temperature/humidity alarm thresholds.

TCW122B-CM is a multifunctional device for remote environmental monitoring and control, designed to work in Ethernet networks. It can be managed by WEB interface, SNMP programs and  user applications. The controller can be used as standalone device or as a part of data acquisition(SCADA) systems.

TCW122B-CM has two relays with normally open and normally close contacts. The both relays can be activated locally – from status of monitored parameters or remotely – by WEB interface, SNMP managers and HTTP/XML API commands.

TCW122B-CM utilizes special schematic for long 1-Wire interface support, up to two temperature or temperature+humidity sensors can be connected. Along with ambient parameters, two analog voltages and status of two digital inputs can be monitored. For every parameter can be sent e-mail and/or SNMP trap for any alarm condition.

There has been a recent update to the TCW122B-CM where descriptions are part of the alarm email. Another important change is the modified user interface.The new FW version 3.0 can be downloaded from here.
