The PXR3-BAA2-4VMA1: The 1/32 DIN (24x48mm) front panel fits the standard cutout — 22.2 x 45 mm — leaving room for additional controllers in a multi-zone panel. Spring-cage terminals accept 0.2–1.5 mm² wire; strip length 7 mm avoids whiskers under the clamp. The RS485 Modbus port shares the same terminal block; daisy-chain up to 31 units on a single master without an external repeater at 19200 baud.
Input and output logic
The universal analog input handles 4-20mA DC or 1-5V DC without a shunt resistor — the controller auto-detects the signal type on power-up. Both relay outputs are SPST-NO rated for 3 A at 250 VAC resistive; one typically drives the heating element, the other can serve as a high/low alarm or cooling output. No alarm output is built into the base unit, so if you need a dedicated alarm relay, configure one of the two outputs for that role.
