SFAR-1M-4DOSfAR 1M 4DO is a controllers 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
