Relays Module for PDW30 & PDW90 Field Units

The PDWM-2RY Relays Option Module is an optional upgrade for compatible PDW30 and PDW90 field units that adds two Form A (SPST) relays to expand field output capability. This module is ideal for applications that require relay-based indication or control at the field unit, such as activating alarm lights, horns, or other discrete devices in response to signals transmitted through the wireless system. In the PDW90 system, the relays are controlled by the digital outputs on the base station, making them a practical way to extend alarm and control functions wirelessly to the field.

The module can be ordered factory installed for either hazardous location or general purpose applications, or purchased separately for field installation in general purpose applications only. It mounts in the base of the enclosure and provides a convenient way to add relay capability to the field unit for local alarm and control functions.
