Description
Yokogawa YS1700-100A06A31
Technical Specifications: Analog input: 1 channel universal input (thermocouple, RTD, 4-20mA, voltage) Analog output: 1 channel 4-20mA control output Digital input: 2 points Digital output: 2 points Power supply: 100-240VAC Display: LCD graphic display Communication: RS485
Functional Features: Multiple PID control algorithms including PID with feedforward, PID with dead band. Custom sequence logic programming. Auto manual bumpless transfer. Self-tuning PID function. Process alarm and deviation alarm. Data storage of process variables.
Application Scenarios: Chemical batch process, boiler temperature control, furnace control, water treatment plant, small refining unit, building HVAC control.
Performance Parameters: Measurement accuracy ±0.1% of span. Control cycle 0.1s minimum.
Material Composition: ABS plastic housing. FR4 circuit board. TFT LCD display module. Silicone rubber keypad.
Structural Features: Panel mount 1/4 DIN size housing. Front panel with keypad and display screen. Rear screw terminal block for field wiring.
Working Principle: The controller receives process measurement signal from sensor. Internal CPU compares measured value with setpoint value. PID algorithm calculates output value to adjust control valve or actuator. Users modify setpoint and parameters via front keypad. Alarm events trigger digital output action.
Installation Requirements: Panel cutout installation. Install away from direct sunlight and vibration source. Power wiring and signal wiring run separately. Shield cable for analog input signal.
Usage Notes: Calibrate input channel before commissioning. Set alarm threshold according to process requirement. Avoid sudden large setpoint change.
