6.9.2 FLEXio User Programmable Modes
Digital Input Mode (Dry Contact Switch)
For digital input mode, a dry contact switch would be wired into pins 1 and 2 or 3 and 4.
Switching logic voltage is 3.3 VDC and is provided internally by the sensor.
Digital Output Model
For digital output mode, a relay driver circuit would be wired with the maximum rating of 3 VDC and 8 mA to
• Pins 1 (+3.3 V) and 2 (GND)
or
• Pins 3 (GND) and 4 (+3.3 VDC)
This can then be used to drive a latching buffer relay.
Analog Input Mode (0 to 3.0 VDC Analog Input)
For analog input mode, a 0 to 3.0 VDC analog input voltage would be wired to pins 1 or 4 and the ground of the circuit
would be wired to pins 2 or 3, respectively.
Analog Output Mode (0 to 3.0 VDC, 8mA Analog Output)
For analog output mode, the analog output voltage of 0 to 3.0 VDC would be wired from pins 1 or 4 to the analog output
circuit. The ground of the circuit would be wired to pins 2 or 3, respectively.
