System compatibility350LBNN belongs to SIEMENS MOORE 350 series single-loop controller. It works independently for closed-loop process control, and supports data communication with upper monitoring or DCS systems.

FunctionThis panel-mounted PID controller receives analog measurement signals from field transmitters, compares process variable with setpoint and calculates PID output to drive regulating valves. It realizes closed-loop control of temperature, pressure, flow and liquid level. It supports local parameter setting, digital display of process value and setpoint, high/low alarm function and manual/auto mode switching.

InstallationCut off AC power before installation. Insert the controller into cabinet panel cutout and fasten mounting brackets. Wire AC power, analog input, control output and alarm relay terminals following wiring drawing. Configure PID parameters, alarm thresholds and input scaling after power on, then perform loop calibration.

InterfaceRear screw terminal block, analog input terminals, 4-20mA control output terminals, alarm relay terminals, front digital display and operation keys.

Feature350 series single loop PID controller, panel flush mount, manual/auto switching, local setpoint adjustment, high and low process alarm, robust metal housing, suitable for continuous industrial process operation. Obsolete legacy spare part, used for old process control loop maintenance and replacement.

DiagnosticNo display: check AC power supply, fuse and rear power terminals. Control deviation: verify field sensor input signal, re-tune PID parameters. Alarm trigger: check process variable, wiring fault and alarm threshold setting.

Product BriefSIEMENS MOORE 350LBNN is 350 series panel mount single-loop PID process controller, widely used in petrochemical, power, pulp & paper and water treatment industries for single process loop regulation.
