KPM35

Input/output expansion module for KPM30 or KPM31 adjustment module

Description
The expansion board KPM35 is an electronic device designed to increase the Inputs/Outpus in the KPM30 or KPM31 controllers.

Technical specifications

When installing one expansion, a safety Class II transformer rated at least 15VA must be used. It is advisable to keep the KPM35 controller separate from the power supply of the other electric devices (contactors and other electromechanical components) in the electric panel. If the transformer secondary winding is grounded, check that the ground cable is connected to G0 terminal. Make sure that the G and G0 references of all the boards mounted on the panel have the same polarity. (G0 reference must be kept in every board).
