Yokogawa UT35A-010-10-00 Single-Loop Digital Indicating Controller
Product Introduction: A compact, high-performance single-loop digital controller designed for precise regulation of temperature, pressure, flow, and level in industrial processes. It replaces the legacy UT350/UT351 series and integrates advanced control algorithms with intuitive operation, making it ideal for standalone or distributed control applications.
Technical Specifications:
- Input Types: Thermocouples (K, J, T, B, S, R, N, E, L, U, W, PL-2, PR20-40, W97Re3-W75Re25), RTD (JPt100, Pt100), DC current (0–20 mA, 4–20 mA), DC voltage (1–5 V, 0–10 V)
Detailed content
- Control Algorithms: PID, ON/OFF, heating/cooling control, feed-forward control, and auto-tuning
- Control Output: 1×4–20 mA DC (load resistance ≤ 750 Ω)
- Communication: Ethernet (Modbus/TCP), RS-485 (Modbus/RTU, P2P, Coordinated)
- Accuracy: ±0.1% of full scale for input indication
- Control Cycle: Fixed at 200 ms
- Program Steps: 300 steps for sequence control
- Power Supply: 100–240 V AC (50/60 Hz) or 24 V DC
- Operating Temperature: -10°C to 60°C
- Front Panel Protection: NEMA 4X/IP56
- Dimensions: 48 × 96 × 65 mm (W × H × D), compact depth for panel mounting
Functional Features:
- 14-segment large color LCD display with navigation keys for easy operation and status monitoring
- Built-in ladder logic sequence control function compatible with LL50A programming software
- User-configurable function keys and multi-language support (English, Spanish, French, German)
- High noise immunity and stable performance in harsh industrial environments
- Auto-tuning for fast setup and optimal control performance across varying loads
- Support for PV switching and cascade control for complex process requirements
Application Scenarios: Heat treatment furnaces, food processing lines, pharmaceutical reactors, chemical process skids, water treatment plants, and OEM equipment requiring precise single-loop control of process variables.
