Frequently Asked Questions (FAQ)
What does AK 1 to 6 mean?
AK stands for requirement class in safety standards. AK1 is lowest safety level. AK6 is highest safety level for this module.
Can I mix 6 mA and 24 V inputs on the same module?
Yes, you can. Each channel works independently. However, all channels share the same return path.
How do I know if the self-test finds a fault?
The module sets a system fault flag. HIMA CPU reads this flag. Then the system goes to safe state.
What is walking-zero test?
Walking-zero sends a zero signal to each input one by one. This test checks for cross-talk between channels. Consequently, it verifies isolation integrity.
My module fails self-test occasionally. What should I do?
First, check your power supply voltages. Then verify all field wiring. If problem persists, replace the module.
Experience-based tip:
Always use separate shielded cables for each group of 8 inputs. This reduces cross-talk in noisy environments. For very high noise areas, use optical isolation externally.
Which shipping method do you recommend?
We ship via FedEx, UPS, or DHL. All methods include tracking. Delivery takes 3 to 7 business days worldwide.
What warranty do you provide?
We offer 12-month warranty against defects. This covers manufacturing faults only. It does not cover damage from wrong wiring or overvoltage.
Can I use this module with non-HIMA systems?
No, you cannot. This module requires a HIMA backplane and HIMA CPU for safety functions.
