Interface relay Satel MP-1 Green DC 12V 106g

The SATEL MP-1 is a compact interface relay module for low-voltage electrical installations and alarm systems. It contains four electromagnetic relays driven by 12 V DC control signals and five series fuses on the output circuits for overload protection. The module enables switching of higher-current loads and is compatible with control panels and modules that provide voltage or open-collector (OC) control outputs.

Advantages

MP-1 provides isolated relay outputs to control devices with higher current requirements than typical control-panel outputs. Built-in fuses protect connected equipment from overloads. The relays support both DC and AC loads within specified voltage and current limits, and the module’s compact form factor simplifies integration into alarm and low-voltage installations.

Suitable for

• Expanding alarm control panels to switch external devices
• Controlling door releases, sirens, or lighting circuits
• Interfacing low-current control outputs (including OC outputs) with higher-current loads

How to use

Connect the 12 V DC control supply to the module’s coil inputs and wire the controlled circuits through the appropriate relay outputs. Verify fuse ratings and replace fuses only with equivalent types. When using OC outputs from control panels, ensure the panel can provide the required control signal or use an appropriate interface. Follow standard low-voltage wiring practices and de-energize circuits before making connections.

Recommendations

Use MP-1 with compatible alarm control panels and modules (for example CA-5, CA-6, CA-10, CA-64, INTEGRA, VERSA, GSM-4, ETHM-2) and ensure OC outputs do not exceed their rated current; typical OC output capacity is around 50 mA. Do not exceed the specified voltage and current limits for each relay channel.
