About the product

SFAR-S-16RO has 16x RO (Relay Outputs). Relay Outputs are normally open (NO) type relay outputs 230 V AC/ 30 V DC max. 3 A. Each channel can be individually configured in one of several modes. Built-in RS485 interface allows to easy connection over Modbus RTU/ASCII protocol with a PLC makes the modules an external I/O. The use of 32-bit ARM core processor provides fast processing and communication with the baud rate from 2400 to 115200 bps. The module is equipped with a set of LEDs used to indicate the status of outputs, power supply and RS485 communication. This feature is useful for diagnostic purposes and helping to find errors. Built-in mini USB allows for initial configuration of the unit without power supply. To simplify installation the modules have been equipped with Quick Connector system. Using dedicated SFAR-S- LINK cable allows to connect up to 15 modules which provide both RS485 communication and power supply.
