The ECA 32 is placed in the base part of the ECL 310. Communication with the ECL 310: A 2 x 5 male-pin arrangement on the back of the ECL 310 controller connects to the related 2 x 5 female-pin arrangement on the ECA 32, when the ECL 310 is placed in its base part.
Temperature sensors, pulse inputs and analog outputs are connected via the terminals 49 - 62. 4 x relay outputs are via the terminals 39 - 46.
ECA 32 is used only together with ECL 310 and applications having ECA 32 related functions.
Besides, ECA 32 can be used as monitoring module:
6 x temperature sensor inputs (Pt 1000)ECL 310. In the ECA favorite display the ECA 31 will show the relative humidity.
