System compatibility353D2F1LNNNNNNA belongs to SIEMENS MOORE 353D series standalone process controller. It can operate independently for closed-loop regulation, and connect with upper DCS or HMI via serial communication interface.

FunctionThis multi-loop digital PID controller executes closed-loop control for temperature, pressure, flow and liquid level. It supports auto-tuning PID, cascade control, ratio control and feedforward control. Operators can set parameters, view real-time process values and check alarms through front keypad and LED/LCD panel, also support simple sequence interlock logic.

InstallationDisconnect power before installation. Embed the controller into cabinet panel and lock mounting clips. Wire analog input, control output, alarm relay and power terminals following wiring diagram. Complete PID parameter tuning and communication address configuration after power on.

InterfaceRear analog input terminals, analog output terminals, relay alarm terminals, RS485 communication port, front panel display and operation keypad.

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

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

Product BriefSIEMENS MOORE 353D2F1LNNNNNNA is 353D series multi-loop digital PID process controller, widely used in petrochemical, boiler and water treatment industries for temperature, pressure and flow closed-loop control.
