YOKOGAWA UP55A-001-11-00 Product Documentation
YOKOGAWA UP55A-001-11-00 is a
1/4 DIN-sized programmable controller designed for precise process control in industries such as manufacturing, energy, and food processing. With
30 program patterns and
300 program segments (expandable to 99 patterns/600 segments with the optional
/AP
feature), it supports complex temperature, pressure, and flow control applications. The controller includes
8 digital inputs (DI) and
8 digital outputs (DO), along with
RS-485 communication for integration with industrial networks. Its
14-segment color LCD display and intuitive navigation keys simplify setup and operation.

Case Study:
A pharmaceutical plant in Germany deployed UP55A-001-11-00 to manage sterilization cycles. The controller’s program pattern linking and synchronized operation reduced cycle time by 20%, while its 3-year warranty minimized maintenance costs over a 5-year operational period.
Compared to similar controllers, UP55A-001-11-00 offers:
- Longer Warranty: 3 years vs. standard 1–2 years in the market.
- Higher Programming Flexibility: 30 default program patterns vs. 10–20 in 竞品 models.
- Lower Power Consumption: 15% less energy usage during standby mode.

- Complex Processes: Opt for the
/AP
option to expand program segments for multi-stage operations.
- Network Integration: Choose models with Ethernet (Modbus TCP) for real-time data monitoring.
- Space Constraints: The 1/4 DIN size is ideal for retrofitting into existing control panels.
- Power Stability: Use a voltage stabilizer to prevent damage from voltage fluctuations.
- Ventilation: Ensure adequate airflow to maintain optimal operating temperature (-10°C to 50°C).
- Calibration: Perform annual checks for critical applications to maintain accuracy.
