Backplane Communication Velocity and I/O Density Scaling
The module communicates via the local base plate, processing 8 independent RTD channels across four dual-channel 16-bit A/D converters. The internal firmware update cycle achieves complete 8-channel scanning every 450 msec. High I/O density is balanced by channel-to-logic galvanic isolation rated at 1500 V for up to 1 minute, preventing field surges from compromising backplane bus communication stability.
Frequently Asked Questions
Q: What power connection base plates are compatible with the AI03 module?
A: Module power requirements (24 VDC +/- 10%) are supplied via the POWER TB located on the cHBX01L or VBX01T base units.
Q: How is open circuit detection handled for connected RTD sensors?
A: The module incorporates automatic diagnostics capable of detecting an open circuit condition on any configured RTD channel in less than 5 seconds.
Q: What are the module keying assignments for base slot configuration?
A: Mechanical keying codes are designated as slot #1 = 13 and slot #2 = 20 to prevent incorrect module insertion.
Field Installation Guidelines
- Mount the module vertically or horizontally into the corresponding base unit slot, ensuring mechanical keying codes (slot #1 = 13, slot #2 = 20) line up properly.
- Maintain proper cable routing for field signal wiring, limiting total wire run length to a maximum of 600 meters (1968 feet).
- Connect 2-wire, 3-wire, or 4-wire RTD sensors according to terminal base schematics, ensuring proper shielding techniques to preserve the -90 dB common mode rejection profile.
- Verify that supply power at the POWER TB on cHBX01L or VBX01T remains regulated at 24 VDC +/- 10% prior to powering the subsystem.
