Panel fit and signal routing
The control output is a single-pole single-throw (SPST) relay contact, rated for on/off or time-proportioning control of heaters, solenoid valves, or contactor coils. The high/low alarm output (1 point) provides a dedicated relay for out-of-range conditions, separate from the main control output — useful for annunciation or safety interlocks without external comparators.
Retransmission and programming
An additional 4-20mA DC retransmission output is built in, allowing the controller to send the process value or setpoint to a remote recorder, PLC analog input, or SCADA system. This avoids an external signal isolator or splitter when the loop needs to be shared. Programming uses North American code conventions, so the parameter structure and units default to familiar US/Canadian process engineering norms rather than Japanese or European defaults.
