Wiring the Basic I/O Module
1.
Power:
5-24 VDC, 2.5W peak. Connect either ground pin to chassis ground.
2.
Discrete output:
Opto-isolated, current source or sink, depending on wiring; must connect logical ground to
common. Outputs are opto-isolated and protected against reverse polarity. Max current 50 mA @ 24 VDC. Output
1 used for external illumination control by default.
3.
Trigger input:
Opto-isolated, polarity-independent, current source or sink; have reference to a separated
common signal. Work with ±10-30V. Input 0 is dedicated trigger line.
Note
: You must use a null modem cable when connecting the Basic I/O Module to a PC’s RS-232 serial port.
