Relay Modules MRPA

with SPDT relays

Description

Relay module MRPA may be equipped with 1, 4, 8, or 16 relays. Each relay, either the plug-in or solder type, has SPDT contacts. For DC operation, a diode in series with the operating current prevents operation when incorrect polarities are applied. An LED shows relay operating status, and a diode across the coil protects the circuits from reverse voltage. The positive operating modules employ a negative bus, whereas the negative operating modules use a positive bus. In the case of AC operation, diodes are omitted. Best switching characteristics are obtained when mounted with the input side downward, or in a horizontal plane.
