The PXR3-REY2-4VRA1 is a 1/32 DIN (24x48mm) temperature and process controller from the PXR series, sized for tight panel cutouts where every millimeter counts. Its self-tuning algorithm handles PID autotune on startup, and the 16 ramp/soak segments let you profile a multi-step thermal cycle — annealing, curing, or sterilization — without an external programmer. Control output 1 is a current output, so it drives a 4-20mA final control element (valve positioner, SCR power controller, or analog VFD input) directly. The retransmission output (4-20mA DC) mirrors the process value or setpoint to a PLC analog input, chart recorder, or remote display — useful for data logging without a dedicated loop. Input signal is thermocouple in °F, so it reads Type J, K, T, or other common TC types (the spec does not narrow which). The universal power supply (100-240V AC, 50/60Hz) means it works on North American 120V or European 230V without a step-down transformer — one SKU for global panels.
Integration notes
The 1/32 DIN form factor (24x48mm panel cutout) fits standard DIN-rail adapter or panel-mount bezel. Programming uses North American Code conventions. No alarm output on this variant. If the application needs a high/low alarm relay, the PXR3-REY2-4VRA1 is not the right pick — look at the PXR3-REY2-4VRA1's sibling with alarm output. The retransmission output can serve as a remote signal for alarm monitoring at the PLC, but it is not a hardwired alarm contact.
