Relay module Ropam RM85 12V single-pole (RM85-12V-1P)

Ropam RM85 12V single-pole (RM85-12V-1P) is a compact electromechanical relay module with a 12 V coil and a single-pole changeover contact. It is designed to provide a simple switching interface between control systems such as alarm panels or automation controllers and connected loads. The module offers a space-saving solution for switching circuits where a single contact is sufficient and where a reliable 12 V coil operation is required.

Advantages

The relay module features a compact footprint and straightforward electrical characteristics that make it easy to integrate into existing systems. Its single-pole contact design simplifies wiring in applications where only one circuit needs to be switched. The 12 V coil voltage is compatible with common low-voltage control panels and power supplies. The device’s mechanical switching delivers clear on/off states, aiding predictable operation in building automation and security installations.

Suitable for

• Switching of low-voltage loads from alarm and security control panels
• Integration into building automation for controlling devices such as valves, small motors or lighting circuits
• Use as an interface between automation controllers and higher-power loads that require isolation
• Replacement or expansion of a single-contact relay stage in equipment control racks

Key specifications

• Coil voltage: 12 V DC
• Contact configuration: single-pole (1P)
• Contact type: electromechanical changeover contact
• Typical use: switching and isolation between control outputs and loads
• Form factor: compact relay module suitable for panel or module mounting

How to use

Mount the relay module in the appropriate enclosure or panel location and wire the coil terminals to a stable 12 V DC control output. Connect the load circuit to the relay contact terminals following the intended normally-open or normally-closed configuration. Verify polarity and supply voltage before energizing the coil. After wiring, test the relay operation by activating the control output and confirming that the contact changes state and the load is controlled as expected.

Usage recommendations

Use wiring and protection (fuses or circuit breakers) appropriate to the switched load current and voltage. Avoid exceeding rated contact current and ensure appropriate transient suppression when switching inductive loads. Periodic functional checks are recommended in security and automation systems to confirm reliable operation.
