TCW121B is a new member of Teracom’s Ethernet controllers.

It is a successor of the popular TCW120B. The new feature is monitoring and control of relative humidity and temperature. The both relays can be activated independently, not only manual but also from the status of monitored parameters – temperature, humidity, analog voltage and logic level or dry contact connection. Only one parameter can manage the relay at the same time, but for every parameter can be sent an e-mail if it goes outside of previously set-up range. More details can be found on TCW121B product page.
