The B842–008 reed relay output module, normaly closed, converts the signals used on the 800 series OURBUS to 8 independent mercury wetted reed relay outputs capable of driving relays, pilot lamps, or other loads up to 2.0 amperes, or low level circuits such as analog multiplexing.

The module uses eight high reliability mercury wetted reed relays to control loads. Each output is electrically isolated from the I/O Bus and from the other seven outputs by the coil of the relay and will withstand the severe voltage transients normally encountered in industrial environments without damage or adverse effect on the controller.

Self-contained resistor and capacitor snubber networks suppress transient voltages when inductive loads are driven and provides contact protection. The eight outputs are also fused to protect their circuitry against overload currents.

The B842–008 reed relay output mdule is compatible with input modules.
