System compatibility353A4F1NNNNNNA belongs to SIEMENS MOORE 353 series standalone process controller. It can work independently for loop control, and communicate with host DCS/HMI system via serial communication.

FunctionThis multi-loop PID controller performs closed-loop regulation for temperature, pressure, flow and level. It supports auto-tuning PID, cascade control, ratio and feedforward control modes. Local parameter setting and real-time process value display via front keypad and LCD screen.

InstallationCut off power before installation. Insert the unit into control cabinet panel and fasten mounting clips. Wire analog input, control output and power terminals according to wiring diagram. Set PID parameters and communication address after power on.

InterfaceAnalog input terminals, analog output terminals, relay alarm output, RS485 communication port, front LCD display and keypad.

FeatureAuto-tuning PID algorithm, multiple control modes, local display and operation, alarm function, strong anti-interference for continuous plant operation. Obsolete legacy spare part, used for process loop controller replacement and maintenance.

DiagnosticNo display: check AC power supply and power terminal wiring. Control deviation: recalibrate PID parameters, verify sensor input signal. Communication failure: check RS485 wiring, terminal resistor and station address.

Product BriefSIEMENS MOORE 353A4F1NNNNNNA is 353 series multi-loop PID process controller, widely used in petrochemical, boiler, water treatment for temperature, pressure and flow closed-loop control.
