Emerson KJ4001×1-CA1 124V
Technical Specifications: Field rated voltage: 124 V Control power supply: 24 VDC Backplane communication: DeltaV M series high speed backplane bus Isolation voltage: 1500 VAC between field and control side Operating temperature: 0 ℃ to 60 ℃ Storage temperature: -40 ℃ to 85 ℃ Relative humidity: 5% to 95% non-condensing Mounting: 35 mm DIN rail mounting
Functional Features: Supports hot swap of DeltaV M series I/O electronic modules. Built-in overcurrent protection for field signal loops. LED indicators display power, communication and fault status. Backplane bus realizes high-speed data exchange with controller. Electronic module identification for automatic system configuration. EMC filter circuit suppresses industrial electromagnetic noise. Modular structure allows quick replacement during maintenance.
Application Scenarios: Refinery process control cabinet, chemical continuous production DCS system, power plant boiler auxiliary control, mining process automation, large refrigeration unit control system, food and beverage process control.
Performance Parameters: Bus communication cycle: 1 ms Vibration resistance: 10 Hz to 150 Hz, 0.5 g Shock resistance: 10 g peak acceleration, 11 ms duration MTBF value: 208000 hours
Material Composition: Carrier housing uses UL94-V0 flame-retardant engineering plastic. Main PCB adopts FR-4 glass fiber epoxy substrate. Backplane connector pins use gold-plated copper alloy. Terminal contact components are nickel-plated brass. DIN rail clip is stainless steel.
Structural Features: DIN rail plug-in carrier base. Top locking mechanism fixes I/O electronic module. Front panel is equipped with status LED indicators. Rear multi-pin connector connects rack backplane power and communication bus. Internal partition separates high voltage field circuit and low voltage control circuit. Vent slots are reserved for passive heat dissipation.
Working Principle: The carrier obtains 24 VDC control power from rack backplane. It provides stable power supply and bus communication channel for the inserted I/O module. Field 124V signals connect to carrier terminals and transmit to I/O module after protection and filtering. The carrier uploads field signal status to DeltaV controller through backplane bus. When I/O module fails, users can pull out and replace module without disconnecting field wiring.
Installation Requirements: Install carrier on standard 35 mm DIN rail inside control cabinet. Keep enough vertical space above and below carrier for heat dissipation. Route high voltage field wiring separately from low voltage signal cables. Tighten terminal screws according to torque specification. Cut off rack power before installing or removing carrier base.
Precautions for Use: Confirm field voltage matches 124V rating before wiring. Wear anti-static wristband during maintenance work. Check terminal tightness regularly. Keep ventilation slots free of dust accumulation. Do not install in environment with conductive dust.
