Intelligent Input/Output and Sensor device equipped with 2 digital inputs, 2 digital outputs, 2 analog outputs, and an SIO Bus. 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. The analog outputs are 4–20 mA or 0–20 mA, highly precise and stable, galvanically isolated. The SIO Bus allows integration of additional inputs/outputs and/or environmental sensors via Milli Pro devices. Up to eight alarms can be configured to drive digital outputs and/or generate status signals on Modbus registers. Communication protocol: Modbus-RTU RS485. Firmware remotely upgradeable. Power supply: 12 VDC. Gray enclosure, size: 125 x 40 x 85 mm.
