Point voltage parameters
You can determine the condition of on-board points 1 to 8 by measuring the voltage across the
point input terminal (1 to 8) and the point COM terminal. The sensor loop wiring must be
connected and the 1 kΩ EOL resistor must be in place.
Loop
Voltage range
Open Greater than 3.7 VDC, but less than 5.0 VDC.
Normal Greater than 2.0 VDC, but less than 3.0 VDC.
Shorted Greater than 0.0 VDC, but less than 1.3 VDC.
