Sensaphone® ISACC Instruction Manual
remove the acrylic panel. Using needlenose pliers, move the shunt to the appropriate position. See diagrams below. Replace the acrylic panel when finished.
TEMP position - The default configuration connects the input signal to a 5V reference through a 6.34K pull-up resistor. This configuration allows a thermistor, dry contact (N.C. or N.O. ), or pulse counting sensor to be wired to the input. You may use either a 2.8K ther- mistor or a 10K thermistor with ISACC.

4-20mA position - This configuration connects the input signal to a 249 Ohm load resistor. This allows ISACC to measure the current at the input. Any sensor that puts out 4-20mA can be wired to this input.

0-5V (NO SHUNT) position - This configuration connects the input signal directly to ISACC’s analog to digital converter for measuring the output of 0 to 5 volt transducers. Any sensor that puts out 0-5V can be wired to this input.

CAUTION: Wiring sensors with shunts in the incorrect position could result in damage to the unit.
