Intelligent Input/Output and Sensor device equipped with 4 analog inputs and an SIO Bus. The analog inputs are configurable to acquire external sensors with ranges of -10 to 10 V (compatible with 0 to 10 V, 0 to 5 V, -5 to 5 V, and 4 to 20 mA with a 200-ohm resistor). The SIO Bus allows integration of additional digital and/or analog inputs/outputs and/or environmental parameter sensors, even after commissioning, through Milli Pro devices. Up to eight alarms can be configured to drive digital outputs and/or generate status signals on Modbus registers. The device has a power LED, a status LED, and an RS485 communication LED. Communication protocol: Modbus-RTU RS485. Firmware remotely upgradeable. DIN rail mounting, 4-module size. Power supply: 230–240 VAC.
