Product Short Description
UP55A is a 1/4 DIN program temperature and process controller under Yokogawa UTAdvanced series. It executes segment-based program setpoint control, widely used for temperature curve control in thermal processing equipment.
Technical Specifications:
- Power Supply: 100~240 VAC (+10%/-15%), 50/60 Hz
Description
- Power Consumption: 18 VA
- Display: 14-segment color LCD
- Program Capacity: Max 30 program patterns, total 300 segments
- Segment Time Range: 0.00 ~ 999.59 (hour.minute / minute.second)
- Input: Universal process input (thermocouple, RTD, DC voltage/current)
- Operating Ambient Temperature: -10°C ~ +50°C
Function Features:
Built-in PID, fuzzy control and ladder sequence function; supports PV event and time event trigger; program waiting and synchronous operation; supports Modbus RTU/TCP communication; multiple alarm functions.
Application Scenarios:
Industrial furnaces, environmental test chambers, semiconductor thermal processing, food thermal treatment, laboratory temperature control equipment.
Material Composition:
ABS plastic front panel, metal internal frame, LCD display unit, signal processing circuit board, plastic terminal base.
Structure Features:
1/4 DIN panel mounting structure; front operation keys; rear wiring terminal block; compact depth (65 mm).
Working Principle:
Collects process variable signal from sensors, compares measured value with program setpoint curve, calculates control output through control algorithm to adjust heater, valve or actuator to follow preset temperature curve.
Installation Requirements:
Panel cutout installation; ensure ventilation around the instrument; avoid installation near heat sources and vibration sources; separate power wiring and signal wiring.
Usage Notes:
Do not use 24 V power supply variant for AC 100-240V model; prevent terminal block over-tightening; regularly calibrate measurement input accuracy.
