Ropam Controlo de iluminação EXP-LIGHT16-RN – Módulo de extensão de relés de 16 canais para barramento RopamNet

In a smart building installation, the Ropam EXP-LIGHT16-RN acts as a 16-channel relay expansion module, enabling centralized control of lighting circuits, blinds, or other low-power devices. It connects to any Ropam controller with a RopamNet bus, such as NeoGSM-IP or OptimaGSM, and provides potential-free relay outputs rated up to 230V AC or 24V DC at 1A per channel. This makes it suitable for residential, commercial, and light industrial automation projects where additional relay outputs are required beyond the main controller's built-in capacity.

Key specifications

• 16 independent relay outputs (normally open, potential-free)
• Max switching capacity: 1A per channel, up to 230V AC or 24V DC
• Communication via RopamNet (RN) bus – simple 2-wire connection to compatible Ropam controllers
• Power supply: 10-14V DC from the RopamNet bus (no separate power adapter needed)
• Current consumption: 50 mA standby, 200 mA with all relays active
• DIN rail (35mm) or surface mount installation
• Operating temperature: -10°C to +55°C
• IP20 protection, plastic enclosure
• LED indicators for power, bus activity, and each output status
• Up to 8 modules can be connected to a single Ropam controller (system dependent)

Why choose it

The EXP-LIGHT16-RN offers a cost-effective way to expand the relay count of a Ropam automation system without replacing the main controller. Its bus-powered design simplifies wiring, and the potential-free contacts allow switching of various loads, from LED lighting to small motors. The clear LED indication per channel eases commissioning and troubleshooting. With a compact DIN-rail housing, it fits neatly into standard electrical panels.

Ideal use cases

• Residential smart lighting: control up to 16 separate lighting circuits from a single Ropam controller.
• Building automation: manage blinds, curtains, or ventilation fans in offices or hotels.
• Retrofit projects: add relay outputs to existing Ropam installations without replacing the main unit.
• Light industrial control: switch low-power devices such as solenoid valves, indicators, or small pumps.

Good to know

The module is designed for indoor use only (IP20) and should be installed in a protected environment such as a distribution board. It requires a Ropam controller with RopamNet bus support; refer to the controller's documentation for the maximum number of expansion modules allowed. The relay outputs are normally open and do not provide a closed contact when the module is unpowered. Screw terminals accept wire sizes up to 1.5 mm².
