Technical Specifications: Control Object: AC contactor coil driving Control Coil Voltage: Standard industrial AC coil voltage grade Feedback Signal: Contactor auxiliary contact state feedback input Operating Power Supply: Matched control loop power supply Operating Temperature: ‑20°C to +60°C Storage Temperature: ‑40°C to +85°C Relative Humidity: 5%‑95%, non‑condensing Mechanical Dimension: Standard cabinet‑mount modular unit Certifications: CE, industrial low‑voltage electrical compliance standards
Functional Features: Stable driving output for matched CK series contactor coil. Collect auxiliary‑contact feedback signal to judge contactor pull‑in and drop‑out state. Basic surge suppression protection for coil control loop. Abnormality feedback output when contactor action state is inconsistent with control command. Designed for cabinet fixed installation, used for contactor control loop transformation and spare‑part replacement.
Application Scenarios: Industrial motor starting cabinet contactor control loop. Old‑generation low‑voltage power control cabinet maintenance spare‑part replacement. Manufacturing‑plant power‑distribution cabinet auxiliary control unit.
Structural Characteristics: Compact cabinet‑mount housing structure. External terminal blocks for coil driving output, auxiliary‑contact feedback and power‑supply wiring. Internal surge absorption components for coil loop protection. Metal fixing hole for screw‑mount installation inside control cabinet.
Working Principle: After receiving external control command, module outputs driving voltage to contactor coil to realize contactor pull‑in. Auxiliary‑contact feedback signal is transmitted back to module through wiring. Module compares actual feedback state with control command. If action state is inconsistent, abnormal feedback signal will be output. Surge absorption component suppresses reverse surge voltage generated at coil power‑off moment.
Installation Requirements: Fix module firmly on cabinet mounting rail or mounting plate via fixing holes. Strictly follow wiring diagram to complete coil driving output, auxiliary‑contact feedback and power‑supply wiring. Confirm control‑loop voltage matches coil rated voltage before power‑on operation. Cabinet shell shall complete safety grounding according to electrical specification. Keep operating environment without condensation and within temperature‑humidity limits.
