RS485 communication supports both MODBUS and Fuji's Z-ASC protocol, selectable by configuration — so it drops into a MODBUS RTU network natively, but also speaks the older Z-ASC if the site has legacy Fuji PLCs or SCADA that expect that frame. A digital input is available, triggered by an external switch or similar dry contact, and can be assigned to functions like SV selection or other events — useful for locking out setpoint changes or switching between recipes without entering the menu. ## Control functions and alarms The controller handles both heating and cooling control, and can adapt to step self-heating performance — meaning it manages zones that alternate between heat and cool demand, such as a mould temperature regulator or a chamber that cycles. A heater break alarm is built in, which detects open-circuit or partial failure in the heater load — the kind of fault that, if missed, can ruin a batch or let a process drift before the operator notices. Multiple alarm functions are configurable: delay action, excitation/non-excitation switching, and lock combination — so you can set latching alarms that need a manual reset, or delayed alarms that ignore brief transients on startup.","metaTitle":"Fuji PXR4TAY1-1V000 Temperature Controller, PV 13mm SV 11mm","metaDescription":"Fuji PXR4TAY1-1V000 digital temperature controller with 13mm PV display, 11mm SV display, RS485 Modbus/Z-ASC, heater break alarm.
