Description

MODEX controller module for more switching configurations in the Ex area. The standard twoposition controller monitors limit values (limit monitor). The analog input signal is compared with the potentiometer setpoint.

A floating relay changeover contact is provided as output. The two-point controller is available with overcurrent/undercurrent detection, current output and signalling relay. The current output allows you to loop in (input current balancing) further devices up to a total load of 400 O into power circuit (4 to 20 mA).
