Ropam EXP-I8-RN-D4M expansion module — Ropam input/relay module, 8 inputs with relay outputs

The Ropam EXP-I8-RN-D4M expansion module extends the input/output capabilities of compatible Ropam control systems by providing eight discrete inputs paired with individual relay outputs. It is designed for integration with access control, alarm and building automation systems to monitor external sensors, door contacts, or control circuits through relay switching. The module supports low-voltage discrete signals and mechanical relay contacts for straightforward interfacing with common devices used in security and automation installations.

Advantages

The module provides a compact way to increase the number of monitored inputs and switched outputs without altering the main controller. Each input is matched with a relay output to simplify wiring and logic mapping. The mechanical relays deliver galvanic isolation between control electronics and switched circuits, reducing potential interference. The device is engineered for reliable operation in typical building automation and security environments and allows centralized management via the host controller.

Suitable for

• Expanding access control panels to add door or zone monitoring
• Integrating additional sensors into alarm systems
• Controlling auxiliary circuits such as sirens, lights or door strikes
• Adding discrete I/O in building automation and facility monitoring

Key specifications

• Number of inputs: 8 discrete inputs for sensors or contacts
• Outputs: 8 corresponding mechanical relay outputs (single-pole changeover/contact type)
• Interface: designed for direct integration with compatible Ropam control units
• Signal type: low-voltage digital inputs; relays provide isolated switching
• Mounting: panel or DIN-rail compatible enclosure for installation in control cabinets
• Operating environment: suitable for indoor use in security and automation panels

How to use

Connect each external sensor or contact to a dedicated input terminal, and wire the corresponding relay output to the device or circuit you intend to switch. Integrate the module with the host Ropam controller following the manufacturer’s wiring and communication guidelines so the controller can read input states and command relay changes. Ensure power and signal wiring adhere to local electrical standards and that the enclosure provides appropriate protection for the installation environment.

Usage recommendations

Prioritize separating power and signal wiring to minimise electrical interference and observe relay switching current ratings when selecting loads. Verify compatibility with the host controller firmware and configure input-to-relay mapping within the control system to match the intended logic for access control or alarm responses.
