Intelligent Input/Output and Sensor device equipped with 4 digital inputs, 4 digital outputs with separate commons, and an SIO Bus. The digital inputs are opto-isolated and include a debounce filter, typically used for counting externally generated pulses or as remote status indicators. The digital outputs are opto-isolated transistor type, rated 27 VDC / 27 mA according to DIN 43864, and can be programmed as internal alarm outputs or as remotely controlled output units via serial line and Modbus commands. The SIO Bus allows integration of additional inputs/outputs and/or environmental sensors through 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.
