Frequently Asked Questions

Q: Can I mix 24V DC and 120V AC outputs on this module?
- A: No, this module supports 24V DC outputs only. Use 6ES7422-1BL00-0AA0 for AC applications.
Q: What is the maximum cable length for outputs?
- A: Shielded cable up to 1000 meters, unshielded up to 600 meters.
Q: Does this module support hot-swapping?
- A: No, power down the S7-400 rack before removal or installation.
Q: How do I enable diagnostic alarms?
- A: Configure the module in STEP 7 and enable “Diagnostic interrupt” in the properties.
Q: Can I use this module with ET 200M remote I/O?
- A: Yes, it works with IM 153-1 or IM 153-2 interface modules.
