Deterministic Network Integration and I/O Density Scaling

The AGPS-21C power supply converts incoming AC line power to stabilized 24 VDC power rails that energize system backplanes and field bus nodes across Profinet and EtherNet/IP deterministic networks. Internal voltage monitoring circuitry regulates output rail stability during high-load switching events, supporting maximum I/O density scaling across expanded automation racks. Built-in filter stages maintain low noise figures on internal buses to preserve backplane bus communication velocity and ensure seamless firmware flash compatibility across active controller modules.

Frequently Asked Questions

Q: Does the AGPS-21C support hot-swapping while the host system backplane is fully powered?

A: No, primary AC input power and output load connections must be isolated prior to inserting or removing the power supply module to prevent electrical arcing and logic reset faults.

Q: How is the primary input voltage configured on the AGPS-21C?

A: The module accepts selectable 115 VAC or 230 VAC line inputs, configured via onboard terminal taps or jumper selection prior to energization.

Q: What primary output potential does the AGPS-21C deliver to connected system cards?

A: The unit provides a regulated 24 VDC output loop designed to power rack backplane buses and connected local I/O modules.

Field Installation Guidelines

  • Isolate all primary AC mains supplies and load circuits before mounting or servicing the power supply module.
  • Verify proper earth ground bonding between the module mounting chassis and the enclosure DIN rail or rack frame to ensure noise suppression.
  • Ensure correct input voltage tap selection (115 VAC or 230 VAC) matches site power before applying main distribution potential.
  • Maintain minimum vertical clearance of 50 mm above and below the power supply housing to facilitate natural convection heat dissipation.
