Backplane Bus Communication Velocity and Network Determinism
The board provides regulated 28 VDC excitation rails across connected IONet network devices and distributed I/O packs to prevent network dropouts. Solid-state PTC devices limit branch overcurrent, ensuring localized electrical faults do not disrupt primary VME backplane bus communication velocity or degrade EtherNet/IP and IONet deterministic network execution across adjacent rack modules.
Frequently Asked Questions
Q: How does the power board protect downstream I/O packs during overcurrent events?
A: Each individual I/O pack branch output incorporates a positive temperature coefficient (PTC) device that automatically increases resistance during fault currents and resets once the thermal overload condition clears.
Q: Can multiple power distribution boards connect together for large-scale control racks?
A: Field cabling supports daisy-chain expansion across the 6-pin power input headers to feed additional JPDH boards from a single central 28 VDC source.
Q: What connector types are integrated onto the circuit board faceplate?
A: The board includes 29 female plug connectors, comprising two 6-pin power input headers and twenty-seven 2-pin Mate-N-Lok headers arranged in three rows for direct I/O pack cabling.
Field Installation Guidelines
Ensure all upstream 24/28 VDC primary power feeders are completely de-energized and tagged out before installing the power distribution assembly. Mount the card onto the cabinet DIN rail, pressing firmly until the retention clips engage the rail base to prevent displacement from operational turbine vibration. Grounding straps must connect directly to the enclosure structural frame to establish a low-impedance electrostatic ground path.
Align each 2-pin and 6-pin Mate-N-Lok wire harness connector with its designated board receptacle, pushing straight in until the plastic latching mechanisms snap into place. Route all DC power distribution cabling through designated cabinet wiring channels, keeping a minimum distance of 300 mm from high-voltage AC conductors and motor drive outputs to suppress electromagnetic field coupling. Verify polarity on all incoming power leads prior to energizing the primary power supply.
