- Functional Features:
- Gold-plated copper alloy contact pins (5 μm plating) minimize contact resistance and prevent oxidation/corrosion, ensuring stable electrical connections and high-speed data transfer even after 10,000+ module plug/unplug cycles in industrial environments.
- 96-pin dual row configuration provides dedicated pins for power distribution (24 V DC/5 V DC/GND) and legacy Modicon proprietary backplane bus communication, eliminating cross-interference between power and signal lines for reliable PLC operation.
- 2500 V AC isolation between the power bus and communication bus protects sensitive PLC communication circuitry from high-voltage transients and electrical interference in industrial power distribution systems, preserving signal integrity.
- Reinforced flame-retardant thermoplastic housing (UL 94 V-0) provides mechanical protection and electrical insulation, with resistance to impact, dust, and moisture in harsh industrial control cabinets and chassis enclosures.
- Vibration-resistant screw-fastened mounting ensures the connector module remains securely attached to the PLC chassis backplane in high-vibration industrial environments (e.g., manufacturing machinery, mining equipment), preventing pin loosening and signal/power loss.
- Corrosion-resistant tin-plated metal mounting bracket and IP65-rated mated contact protection ensure reliable performance in humid and corrosive industrial environments (e.g., chemical plants, marine applications, washdown facilities).
- 5 A current rating per power pin delivers sufficient power to legacy Modicon PLC modules (CPU, I/O, communication), supporting fully populated PLC chassis with multiple modules for medium-scale automation systems.
- Low contact resistance (<5 mΩ) ensures efficient power distribution and minimal voltage drop across the backplane, delivering stable power to sensitive PLC electronics (CPU, analog I/O modules) in industrial control systems.
- Direct drop-in replacement for legacy Modicon backplane connector modules enables fast and easy repair of faulty PLC chassis, with no modification to the chassis or wiring required, minimizing system downtime during maintenance.
- Compatibility with all legacy Modicon 8-slot/12-slot PLC chassis and modules ensures seamless integration into existing legacy automation infrastructure, extending the service life of legacy PLC systems without full hardware replacement.
