The OMC-183 Signal conditionings Unit was developed to make an interface with analogue and digital sensors without the requirement to store sensor data. The serial information contains the measured parameters of the sensors connected. The span and offset on each channel can be set via a serial port provided. All this information is stored in EEprom. The OMC-183 consists of 2 printed circuit boards, the processor board and the analogue in/output board. The processor board and the analogue board are connected via a 34-way ribbon cable. The analogue input/output board is only required when analogue inputs and or more analogue outputs are necessary.
Features:
* Free programmable inputs
* 16 Bit conversion
* 8 analogue inputs (only available on OMC-183)
* 4 digital inputs
* Power supply for most of the sensors
* RS232 in– and output
* RS422 in– and output
* 2 analogue 4..20 mA outputs
*6 analogue 0..10 Vdc outputs (only available on OMC-183) | |
