Relay Module ERM-12A

It is used for switching on/off electrical devices. Thanks to its small dimensions, it can be installed in an installation box or where there is a need to control a receiver with a maximum load of 12A.

Application examples:

Controlling a heating appliance (ON-OFF type) by connecting a 230V AC voltage thermostat such as ESIMPLE230 to the relay.

Connecting a receiver with more power than the relay in a thermostat allows.
The maximum current consumption of an electrical device must not exceed 12A.

Relief of outputs in the control box (e.g. ECB08M) with ERM12A in case of use of a larger number of actuators per zone or high power receivers (e.g. electric heating mats)

Description of operation:

The relay must be powered by 230 V AC.
Relay control is done by applying voltage 230 V AC to the input contact SL or by shorting the COM / NO input contacts (VOLTAGE FREE INPUT).

This will switch the contacts in the NO / COM / NC output circuit. The relay operation status is indicated by a blue LED.

After 230 V AC voltage decay from the SL input or after opening the COM / NO volt free input, relay module will return to its original position.
