Description

SCSI/DB Connector End

Uses SCSI 50/36/25-pin (also called VHDCI/HPDB) connectors, a common high-density signal interface in industrial equipment, with locking screws and alignment pins for highly reliable, anti-loosening connections.

The connector end is printed with model identification such as SIM300DI/1 Cable-3M, DI Cable-10M, clearly indicating cable model, purpose, and length for easy on-site installation and maintenance.

This connector type is commonly used for digital input/output expansion interfaces on PLCs, motion control cards, and distributed IO modules.

Gray industrial-grade shielded cable with EMI resistance and wear resistance, suppressing electromagnetic interference from industrial sites to ensure stable digital signal transmission.

Internal multi-core color-coded wires with stripped ends fitted with red insulating sleeves, enabling quick identification of channels, common terminals, and other signals per device schematics.

Application

PLC Digital Input (DI) Signal Acquisition

The most common use of this harness is connecting PLC/industrial computer expansion modules to collect on/off signals from field devices, including:

Sensor signal input: acquisition from photoelectric switches, proximity switches, limit switches, temperature/pressure switches

Device status feedback: motor start/stop, valve open/close, cylinder position, emergency stop button status, etc.

Production line signal collection: centralized transmission of digital signals such as station arrival, product inspection, and fault alarms

Distributed IO Module Expansion

Used to connect the main controller to remote IO modules for long-distance multi-channel digital signal transmission, reducing on-site wire complexity. Suitable for large-scale automated production lines and warehouse logistics equipment.

Equipment Commissioning and System Integration

The bare-wire end design is also commonly used for temporary wire during equipment commissioning, or customized signal wire for non-standard automation equipment, adapting to different device pin definitions and signal allocation requirements.
