SFAR-1M-4DO

SfAR-1M-4DO is a controller’s I/O extension, which gives users the possibility to send multiple signals to multiple devices, for example, to start/stop or alarm reset commands for pumps. The module has 4 digital outputs (DO). Digital outputs are PNP transistor outputs sending voltage signals. All outputs are isolated from the logic with optoisolators. A built-in RS485 interface allows an easy connection over the Modbus RTU/ASCII protocol. A 32-bit ARM core processor provides fast processing and communication. The module is equipped with a set of LEDs used to indicate the status of I/Os, power supply, and RS485 communication.
