• 4 optically isolated inputs for discrete ON/OFF functions
• 6 analog voltage inputs (0 to 5V)
• 2 SPDT Form C relay outputs
In addition,±12VDC is supplied for sensor power and a +5V reference
voltage for sensor excitation is available.
The Sensor port interface is a 25-pin male D connector. The connector
pinouts and their respective functions are shown below.
The analog voltages are routed to a 10-bit analog-to-digital converter (ADC)
which provides a resolution of +/-.1% and an accuracy over temperature of
±0.5%.
