ARC-DI2RDO2 – flush-mounted module for controlling lights and blinds
The ARC-DI2RDO2 is a compact flush-mounted module with two digital inputs and two relay outputs. It is primarily designed for controlling lighting and blinds but (thanks to the option to customise its behaviour) it can also be used for other control functions in building automation.
The ARC-DI2RDO2 is supplied as a single-purpose module. Functions of module are configured via parameters using the RS485 interface and the MODBUS RTU protocol.
The module can operate standalone, with a supervisory control system, or in a combined mode. In standalone mode, it responds to the states of the digital inputs; in mode with a supervisory system, the relay outputs can be controlled and the states of the digital inputs read via MODBUS RTU. In combined mode, both control methods can be appropriately integrated.
