System compatibility15738-80 belongs to Siemens Moore 352E series single loop controller. It can work independently for loop regulation, or communicate with APACS+ DCS system for data exchange, receive 4-20mA signals from field transmitters and output control signals to valve actuators.

FunctionThis 352E digital loop controller executes single-loop PID closed-loop control for pressure, temperature, flow and liquid level. It supports auto/manual mode switching, local setpoint adjustment, alarm function and cascade control. The front panel with display and keys allows on-site operation and parameter configuration. It collects measurement signals from field instruments and outputs 4-20mA command signal to regulate control valve opening.

InstallationCut off power supply before installation. Fit the controller into cabinet panel cutout and secure mounting brackets. Wire AC power, analog I/O and relay alarm terminals. Configure PID parameters, alarm thresholds and communication settings via front panel keys, perform loop test after commissioning.

InterfaceFront panel LED display and membrane keypad, rear screw terminal block for power, analog and digital signals, alarm relay contacts.

FeatureMoore 352E digital single loop controller, built-in PID algorithm, auto/manual switching, high/low alarm function, panel flush mounting, rugged metal housing. Obsolete legacy spare part, used for industrial single process control loop maintenance and replacement.

DiagnosticNo display: check AC power input and power terminal wiring. Control loop deviation: verify sensor input signal, re-tune PID parameters. Alarm cannot reset: check alarm threshold configuration and field process status.

Product BriefSiemens 15738-80 is Moore 352E panel mounted digital loop controller, widely used in petrochemical, power and pulp & paper industries for independent single-loop PID process control.
