Typical Application
Input: A 1-5V DC signal from a controller, sensor, or potentiometer.
Processing: The conditioner isolates the signal and converts it into two different analog outputs.
Output 1: A 4-20 mA signal is sent to a PLC or DCS for control.
Output 2: A 0-10V signal is sent to a variable frequency drive (VFD) or local display.
Status Outputs: The two transistor outputs activate alarms for high/low limits or system faults.
