Description
Yokogawa UP55A Program Controller
Product Dimensions：
The Yokogawa UP55A is a high-performance 1/8 DIN Program Controller belonging to the GREENSERIES line of digital indicating controllers. It is engineered to manage time-based program control profiles (ramp/soak patterns) for temperature, pressure, and flow in advanced thermal processing and industrial manufacturing.
Product Detailed Description
The UP55A features a bright, 14-segment color LCD display and a compact depth, making it ideal for high-density panel mounting. Unlike standard single-setpoint PID controllers, the UP55A executes complex time-based profiles with multiple program patterns and segments. It comes standard with Ladder Sequence Logic capabilities, allowing it to perform localized PLC-like control functions without requiring an external controller.

Product Advantages
- Advanced Program Control: Supports up to 300 segments across 30 patterns, featuring flexible ramp/soak profiles, wait functions, and segment jump operations for complex thermal processing.
- Built-in Ladder Logic Control: Integrates basic sequence logic using Yokogawa’s LL50A parameter setting software, allowing logic control (e.g., interlocks, signal routing) without an external PLC.
- Vivid Color LCD Display: Features a 14-segment color display with scrolling text for parameter names, alarms, and operating guidance, drastically reducing operator error.
- Multi-Loop & Custom Control Algorithms: Capable of controlling up to 2 loops simultaneously or executing cascade control strategies within a compact 1/8 DIN footprint.
- LL50A Configuration Software Support: Parameters and program patterns can be loaded via a dedicated light-loader cable directly from a PC, even while the unit is unpowered.
Important Considerations & Warnings
- Terminal Wiring & Noise: Ensure low-voltage signal lines (TC/RTD inputs) are routed away from high-voltage AC power lines to prevent electromagnetic interference (EMI) from affecting measurement precision.
- Current Input Load Resistor: When using 4–20 mA DC current inputs, ensure the proper external 250\ \Omega precision resistor is wired across the input terminals if required by the model terminal configuration.
- Parameter Backup: Always save a configuration backup file using the LL50A Parameter Setting Software before performing firmware updates or major profile re-configurations.
- Panel Depth Clearance: Although compact, ensure adequate ventilation space around the rear chassis inside the panel cabinet to maintain temperature specifications.
Product Applications
The UP55A is widely deployed in industries requiring precise time-temperature profile management:
- Heat Treatment & Metallurgy: Annealing furnaces, vacuum heat treatment, hardening, and tempering ovens.
- Semiconductor & Electronics: Crystal growth equipment, diffusion furnaces, and environmental test chambers.
- Ceramics & Glass: Kiln temperature profiling, glass annealing, and ceramic sintering processes.
- Autoclaves & Sterilizers: Composite material curing autoclaves and pharmaceutical sterilization equipment.
