Description

Model PRP/DRC/ESP is a Dual Relay Controller, which is fully compatible with Hochiki’s ESP analogue addressable protocol. It has been designed to provide two general purpose relay outputs, each output can be driven separately for control of such devices as dampers or for control of plant and equipment shutdown. A general-purpose auxiliary input is provided which is fully monitored for short and open circuit, the monitoring can be disabled with bit 8 on the DIL switch. The PRP/DRC/ESP utilizes simple DIL switches for reliable addressing and it is available unboxed (as illustrated above) however a separate IP67 rated enclosure is available.
