Test excitation regulation performance and overcurrent protection function.

Interface

AutoMax backplane edge connector,25-pin field gate connector,9-pin field power module port,isolated armature volts terminal,status and fault LED indicators.

Feature

RELIANCE 0-57412,AutoMax DC motor field excitation regulator module.

Independent closed-loop control of motor field current for constant power speed regulation.

Isolated armature voltage sampling circuit to protect control side from high voltage surge.

Four optional current calibration levels to adapt different DC motor excitation parameters.

Multiple dedicated D-Sub connectors for connection with field power unit.

Discontinued obsolete module,supply only for old automation system spare replacement.

Suitable for metallurgy,paper-making heavy-duty DC drive production line renovation.

Diagnostic

Field current unstable:calibration parameter drift or excitation wiring interference;

No field excitation output:field gate connector loose or power module fault;

Armature voltage sampling abnormal:isolated sampling circuit damage;

Module fault LED on:backplane communication failure or module hardware damage;

Overcurrent alarm:motor field winding short circuit.
