FAQ

1. What is the purpose of the programmable input delay feature?
The programmable delay allows users to adjust the off-to-on and on-to-off timings to match specific system requirements, reducing false triggering and enhancing stability.

2. Is this module compatible with other Honeywell terminal blocks?
Yes, it connects seamlessly with the Honeywell TC-TBCH 36-position terminal block.

3. Can this module handle harsh industrial environments?
Yes, its robust isolation and compliance with IEC standards ensure reliability in demanding settings.

4. What is the advantage of isolated inputs?
Isolated inputs prevent interference and ensure independent operation across all channels, improving signal integrity and reliability.

5. How does the module manage inrush currents?
It handles inrush currents up to 250 mA peak, decaying to less than 37% within 22 ms, ensuring stability without activation delays.
