Features:
- Integrates 24 VDC power distribution with relay isolation and switching functions for industrial DCS applications.
- Uses Omron G7SA-5A1B safety relays and P7SA-14P relay sockets to provide dependable electrical isolation and relay performance.
- Combines long mechanical life, IEC vibration and shock compliance, and an IP40 metal enclosure for reliable industrial operation.
MADOKA MR-DPD-021 is designed to simplify relay-based power distribution in industrial automation systems by combining relay isolation and control power switching in one unit. The module helps separate DCS controller circuits from field equipment while distributing 24 VDC control power to connected devices. This arrangement supports stable operation of automation cabinets where reliable relay control is required.
The relay unit incorporates multiple normally open and normally closed contacts through built-in relays K1 to K6, making it suitable for power distribution, interlocking control, and equipment switching. Omron relay components contribute to consistent relay performance, while the specified load ratings allow the module to support both resistive and inductive applications commonly found in industrial installations.
MADOKA MR-DPD-021 is built for dependable operation under demanding industrial conditions. Compliance with IEC vibration and shock standards, combined with an IP40 enclosure and durable SPC-C steel housing with trivalent chromium zinc plating and sprayed surface treatment, enhances long-term reliability. The specified operating temperature, humidity, and altitude ranges allow the module to be installed in a wide variety of industrial control environments.
The MR-DPD-021 MADOKA Relay Unit may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
