System compatibility

Designed for independent process loop control,can connect with PLC,HMI and DCS system via industrial communication,widely used in heating furnace,heat treatment chamber,environmental test chamber,chemical reactor,packaging and pharmaceutical process control.

Function

UT2800 is Yokogawa UTAdvanced series high-performance digital indicating controller.It accepts universal sensor input and executes high-precision PID regulation with auto-tuning function.Built-in ladder sequence logic enables simple sequential control without extra PLC.Multi-group alarm functions detect deviation,input break and hardware abnormal status.Optional communication interface upload PV,SP and alarm data to upper monitoring system.Supports cascade control,feedforward and fuzzy compensation for complex thermal process.

Installation

Panel cutout mounting,secured by mounting clips.Wire temperature/pressure/flow sensors to universal input terminals,select sensor type,control range and alarm parameters via front panel keys.Communication parameters can be set locally or via PC configuration software.

Interface

‑Universal analog input terminals

‑Control output terminals,alarm relay terminals

‑Digital input terminals

‑Ethernet / RS485 communication port

‑LED indicators for PV,SV,alarm and status

Circuit feature

High precision A/D conversion,hardware watchdog,built-in input break detection,anti-electromagnetic interference,stable continuous long-time operation for industrial site.

Feature

UT2800 belongs to Yokogawa UTAdvanced high-end controller series.Common faults:front panel button wear,input circuit drift,communication port damage,display aging.Confirm input signal type and communication option before replacement.

Diagnostic

Sensor open/short,overrange,control output abnormal or module hardware fault triggers alarm and display warning code.

Built‑in function

Precise PID process control,sequence logic,alarm monitoring and data communication for single industrial loop,used for industrial spare replacement.
