Relay module Ropam RM5-12V-4P — 12V input, 4 relay outputs, DIN-mount compatible

Ropam RM5-12V-4P is a compact relay module for control and switching applications. It operates from a 12V DC supply and provides four relay outputs suitable for switching circuits, loads or devices. The module's form factor is compatible with DIN-rail mounting, enabling installation in control cabinets, alarm panels and automation enclosures where space efficiency and tidy wiring are required.

Advantages

The module offers four independent relay channels in a single unit, reducing the number of separate relays and simplifying wiring. DIN-rail compatibility streamlines mounting and integration into existing control panels. Operating from a standard 12V supply makes it compatible with common power systems used in security and automation. The compact design helps save space inside enclosures while keeping connections easily accessible for maintenance.

Suitable for

• Alarm and security systems for switching sirens, strobes or auxiliary devices
• Building automation panels for controlling lighting, motors and actuators
• Remote switching tasks in industrial or commercial installations
• Prototyping and small control cabinets where multiple relay outputs are required

Key specifications

• Supply voltage: 12 V DC
• Number of relay outputs: 4 independent channels
• Mounting: DIN-rail compatible enclosure for control cabinet installation
• Function: electromechanical relay switching for circuits and loads
• Form factor: compact module designed for space-efficient installation

How to use

Connect the module to a stable 12V DC supply observing correct polarity and recommended wiring practices. Wire each relay output to the load or circuit to be switched, following the relay contact designation on the module. Mount the unit on a DIN rail inside a suitably rated enclosure and secure wiring with appropriate terminals and cable management to prevent strain. Verify connections and test each relay channel using the control signals or manual activation procedures defined by the system design.

Usage recommendations

Use appropriate fusing and circuit protection on the 12V supply to protect the module and connected devices. Ensure relay contact ratings match the switched load; for inductive loads, apply suppression measures such as diodes, RC snubbers or transient suppressors. Maintain adequate ventilation in enclosed cabinets and follow local electrical codes during installation.
