Yokogawa UP550-00 1/4 DIN Program Controller
- Product Introduction: It is a 1/4 DIN-sized program controller belonging to Yokogawa’s Green Series, designed for precise program control of industrial process parameters like temperature, pressure, and flow. It integrates program pattern storage, multi-mode control, and real-time display, and has been discontinued with replacement model UP55A-000-11-00. It offers reliable control for heat treatment, chemical synthesis, and other batch processes requiring step – wise parameter changes.
- Technical Specifications:
- Input Type: Universal input, supporting thermocouple (K, J, T, E, R, S, B, etc.), RTD (Pt100, JPt100), 4-20mA DC, 1-5V DC, and mV signals.
- Measurement Accuracy: ±0.1% of full scale.
- Sampling Period: 100ms, 200ms, 500ms selectable.
- Program Capacity: 30 program patterns, 300 segments, 400 events, 8 PV events, 16 time events.
- Control Modes: Single – loop, cascade, loop with PV auto – selector, position proportional, heating/cooling control.
