Finder Pluggable Function Module, Diode

The Finder 99 EMC suppression module contains a free-wheel (flyback) diode to protect relay driver circuits from negative-going voltage spikes. Unlike other modules in this series, it does not have an LED indicator. The module is designed to fit into a compatible socket together with the relay it protects. It has 220VDC operating voltage rating.
