Yokogawa AEPV7D-215 Primary Power Supply Bus Unit

Configured for primary power distribution and redundant supply management in CENTUM VP and N-IO/FIO cabinet platforms, the Yokogawa AEPV7D-215, also cataloged as the AEPV7D Primary Power Supply Bus Unit, provides direct physical/electrical execution. The vertical-type module receives power from two independent 220-240 VAC supply sources to guarantee uninterrupted DC power rails across system backplanes. Connecting input terminals via short cable configurations yields up to 14 distributed output channels for large-scale automation cabinets.

4-20 mA HART Loop Protocol & Channel-to-Channel Isolation

The AEPV7D-215 supplies dual-redundant power to field I/O racks hosting 4-20 mA HART loop protocol modules and high-density analog processing cards. Clean internal power distribution prevents voltage ripple from disturbing low-level sensor signals, maintaining system-wide channel-to-channel isolation. Thermocouple measurement modules powered via the bus retain reference accuracy across cold junction compensation (CJC) circuits without voltage sag or ground loop interference.

Frequently Asked Questions

Q: How does the dual power input configuration function on the AEPV7D-215?

A: The unit connects to two independent 220-240 VAC sources, maintaining continuous bus power output if one primary power line fails.

Q: How can technicians expand output lines on the AEPV7D-215 bus unit?

A: By bridging input terminals with short cable links, the hardware expands from 7 outputs per line up to a total of 14 power outputs.

Field Installation Guidelines

Mount the AEPV7D-215 vertically into designated N-IO/FIO cabinet slots using standard mounting fasteners. Ensure the IP66-rated housing seals properly against the cabinet frame to retain protection against dust and moisture ingress.

Wire dual independent 220-240 VAC supply lines to primary input terminals in accordance with local cabinet power codes. Connect cabinet grounding conductors directly to the dedicated earth lug on the chassis to enforce single-point earthing and mitigate transient surge risks. Maintain proper thermal clearances inside the rack to support natural convection cooling across the operating temperature range.
