Intelligent Input/Output and Sensor device equipped with 4 analog inputs, 2 digital inputs, and 2 digital outputs with separate commons. 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 digital inputs are opto-isolated and include a debounce filter, used for pulse counting or as remote status indicators. The digital outputs are opto-isolated transistor type, rated 27 VDC / 27 mA according to DIN 43864, programmable as internal alarm outputs or as remotely controlled output units. 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.
