The TCW122B-CM is a multifunctional device for remote monitoring and management. It is an Ethernet based controller, which is designed to work in IP-based networks and managed by WEB interface or SNMP programs. The controller can be used as standalone device or as a part of control and monitoring systems.

The TCW122B-CM utilizes special schematic which support long 1-Wire interface. The both relays can be activated not only manual but also from status of monitored parameters - temperature, humidity, analog voltage and status of digital inputs. For every parameter can be sent e-mail and/or SNMP trap if it goes outside of previously set-up range.

Remote control

The controlled device is connected in series with the relay contacts. Users can operate TCW122B-CM using a web browser or SNMP application. Both relays are managed independently.

Data acquisition

The  TCW122B-CM  can be  used  in  Data  Acquisition  Systems  (DAQ).  The device  uses SNMP v.1 protocol for communication with monitoring and management software applications.


The Monitoring page provides information about the state of the relays and digital inputs, values of analogue voltages (applied on analogue inputs), temperature and humidity.

The state of the relay can be changed by appropriate “ON/OFF” button. To change the state of relay for a while “Pulse” button should be pressed. Duration of the pulse is specified in “Pulse Duration” field of “I/O Setup” page.  


Alarms and Automatic Control

For temperature, humidity and analogue values minimum and maximum alarm thresholds can be set. On alarm, the TCW122B-CM can;
  • send an alarm email
  • send a SNMP trap to monitoring software
  • an output relay can be activated. The relay will de-activate when the alarm condition clears. It is possible to use this as a control function.

Android App

TCW12x Remote Control allows you to monitor and control your TCW122B-CM devices. Entering the IP address of your installed ethernet controller, this app will be able to display the sensor values, using SNMP protocol.


  • display temperature and humidity values (up to 2 temperature and 2 humidity sensors are supported)
  • setting the tresholds for the monitored parameters
  • display 2 analogue and 2 dry contact inputs
  • control 2 relay outputs
  • adding descriptions of monitored parameters

TC Monitor Software

TC Monitor is easy to use Windows application for monitoring and control of TCW products. TC Monitor can collect and display data from controllers installed in different locations (sites). The collected data is stored in SQL database and can be displayed or exported in MS Excel format for further analysis. TC Monitor has a simple web interface, which enables easy and fast configuration. Monitored parameters can be 1-wire sensors, digital and analog inputs and relay outputs.

The free version of TC Monitor provides 10 credits, this means up to 10 different parameters can be monitored and logged. More Information >>

Optional Software


ProfiLab-Expert is a low cost graphical programming software package for data acquisition and control applications. No programing experience is needed, programs are written by connecting function blocks together with wires. Professional user panels can be designed with custom controls, and the whole program can be compiled into a stand-alone executable file, with no run-time penalties.
