Notes
1- Switch Sw1 is open to allow voltage-modulated signals to be processed.
The Signal Transmission Mode field has to be set to the Voltage option.
2- Switch Sw2 is set to position 1. This connects the IOC4T card's sensor power supply to
the PS terminal, though in fact this terminal is not used.
the Sensor Power Supply field can be set to any powered option (+27 VDC, −27 VDC,
+15 VDC or +6.16 mA) but should preferably be set to +6.16 mA.
