BX-RIO8

BX-RO16 and BX-RO8 are 16/8-channel DIN-rail-mounted multifunctional actuator for independent switching of loads by by relay contacts. Switching of outputs can also be managed by buttons on the front panel. A green LED indicates the status of the channel. They are equipped with bistable relays with 16 A contacts directly connected to the terminals, without phase sharing. The screw terminals can accommodate wires up to 2.5 mm2 in cross section. The contacts can withstand an inrush current of up to 320 A in the first 2 ms, so they are particularly suitable for driving inductive loads typical of fluorescent or neon lamps. The devices provide switching functions, status notification, lockout command, forcing, timing, delays, scenarios, and management of roller shutters and blinds. They control valves with PWM algorithm and can drive multiple fancoil devices (2 or 4 pipes). They also have a set of logic functions consisting of 16 communication objects of input for each channel; they can be combined with OR, AND, XOR and GATE logic operations.

With the above-mentioned functions, countless combinations can be configured, and this makes it possible to optimize the use of all outputs. BX-RO16 and BX-RO8 are parameterizable by the ETS software, and their versatility makes them particularly suitable for distributed planning; all the operations required to manage a residential or tertiary building will be implementable with a single device.
