Frequently Asked Questions (FAQ)

Q: How many I/O modules can AMN34 hold?
A: The AMN34 chassis accepts up to eight analog I/O modules in a single rack.

Q: Can I replace modules without shutting down the rack?
A: Yes, each module is hot-swappable, allowing maintenance without system interruption.

Q: What power supply voltage is required?
A: A redundant 24 V DC supply (±10 %) is required for the backplane.

Q: Are channels isolated?
A: Yes, each channel is isolated up to 1500 V DC from the backplane to prevent ground loops.

Q: What analog ranges are supported?
A: Configurable for ±10 V or 0–20 mA on both input and output modules.

Q: What is the sampling rate per channel?
A: Each channel can be sampled as fast as every 20 ms.

Q: How is module status indicated?
A: Front-panel LEDs show module presence, error, and warning conditions.

Q: Can I mount the rack on a panel?
A: Yes, the rack includes brackets for DIN-rail or panel mounting.

Q: What environmental conditions can it withstand?
A: Operating from 0 °C to 55 °C and 10 %–90 % RH (non-condensing).

Q: How much does the empty rack weigh?
A: The chassis weighs 2.5 kg without I/O modules installed.
