Applications which use a 10K Thermistor Sensor (non-850 series) universal input require
an 11K ohms shunt resistor kit, AD-8969-206. Install resistor across universal input and common.
4
Applications which use 0 to 20 mA analog inputs require a 250 ohms shunt resistor kit,
AD-8969-202. Install resistor across universal input and common.
To detect a closed switch, maximum resistance must be less than 300 ohms.
To detect an open switch, minimum resistance must be greater than 1.5K ohms.
