Backplane Bus Power Distribution and I/O Density Scaling
The IC694PWR331 module delivers high-capacity DC current directly across the backplane bus, enabling dense I/O expansion without requiring additional sub-rack power injectors. Delivering up to 30 A on the +5 VDC rail alongside an auxiliary +24 VDC tap, this module stabilizes backplane bus voltage levels during simultaneous module switching cycles. Internal bus power conversion circuitry maintains regulation across varying operating loads, preventing system reset triggers caused by voltage dip transients. Furthermore, firmware flash compatibility across RX3i CPU platforms ensures uninterrupted system backplane bus communication velocity across high-density I/O configurations.
Frequently Asked Questions
Q: How is the input voltage selection configured on the IC694PWR331 power supply?
A: Users select between 120 VAC and 240 VAC input sources via an internal wire jumper on the terminal block assembly prior to applying line power.
Q: What precautions are necessary when operating the IC694PWR331 near its maximum 30 A output load?
A: Operation at full current load generates substantial heat; field technicians must maintain unimpeded vertical thermal convection pathways across the enclosure enclosure slots.
Q: Does the IC694PWR331 feature onboard electrical fault recovery mechanisms?
A: The internal logic integrates overvoltage and overcurrent protection loops that trip the output rail to prevent damage, requiring a cycle of input AC line power to reset following a fault.
Field Installation Guidelines
Mount the IC694PWR331 directly into the dedicated power supply slot of an RX3i backplane, ensuring mechanical retention clips fully engage. Ensure the panel environment maintains uninhibited vertical airflow above and below the rack chassis for thermal heat dissipation.
Before applying AC power, verify the 120/240 VAC jumper setting matches the local power mains configuration. Connect field wiring using properly rated crimp lugs on the screw terminals, keeping AC line wiring isolated from sensitive DC signal runs.
Establish a low-impedance ground path by connecting the frame ground terminal directly to the central cabinet earth bus bar using heavy-gauge wire. Verify all chassis ground bonds exhibit minimal resistance to prevent high-frequency noise insertion into the backplane DC supply rails.
