I/O Expander RoGer MCX4D — 4 Inputs, 4 Outputs

RoGer MCX4D I/O Expander — 4 Inputs, 4 Outputs provides additional digital inputs and relay outputs to extend the I/O capacity of control panels and controllers. Designed for integration with building automation, access control and alarm systems, the module enables connection of extra sensors, switches and actuators without replacing the main controller. The compact unit supports flexible wiring and simplifies installation when additional signals or control lines are required.

Advantages

The RoGer MCX4D offers four supervised inputs and four configurable outputs in a single compact module, reducing the need for additional controllers. Its design focuses on straightforward integration with existing control systems, allowing quick expansion of capabilities while maintaining system structure. The device supports common wiring schemes used in security and automation setups and minimizes installation time through a clear terminal layout.

Suitable for

• Expanding input and output capacity of access control panels
• Adding sensors and switches to alarm systems
• Integrating additional actuators or relays in building automation
• Remote I/O extension for controllers with limited ports

Key specifications

• Inputs: 4 digital supervised inputs suitable for sensors and switches
• Outputs: 4 outputs configurable as relay or transistor type depending on installation requirements
• Mounting: DIN-rail or panel mounting for compact installations
• Power supply: low-voltage DC supply compatible with standard control system voltages
• Connection: screw terminal blocks for secure wiring and easy serviceability
• Operating environment: designed for indoor use in control cabinets and distribution boxes

How to use

Install the MCX4D module in the control cabinet and connect the power supply according to the system voltage. Wire sensor and switch circuits to the supervised input terminals and connect controlled devices to the output terminals, observing polarity and load limits. Integrate the module with the main controller following the control system’s interface and addressing method so inputs and outputs appear as extensions of the primary panel. Verify wiring and perform functional tests for each input and output before commissioning.

Usage recommendations

Use the RoGer MCX4D in combination with compatible control panels and follow manufacturer guidelines for wiring and load specifications. For reliable operation, route signal and power cables separately where possible and secure connections with proper torque. Test supervised inputs with the intended sensor types and configure output behavior in the main controller to match the connected actuators’ requirements.
