FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Why is channel current limited?
It controls available circuit current for the documented hazardous-location interface.
What current is documented at 24 V?
No more than 15 mA per channel with the redundant SDI-1624 load.
What resistance defines a closed loop?
Honeywell documents a maximum closed-loop resistance of 250 ohm.
Which hardware must be matched with FC-TSDI-1624C?
Verify Maximum 250 ohm closed-loop resistance, Minimum 15 kohm open-loop resistance and the approved Safety Manager hardware list before installation.
Which diagnostics are important for FC-TSDI-1624C?
Check channel-current limiting, group-fuse protection, open and closed loop state verification and clear every unexplained channel or system alarm.
Can another construction variant replace FC-TSDI-1624C?
Only after environmental construction, certifications, hardware revision and project approval have been confirmed.
What commissioning checks are required for FC-TSDI-1624C?
Perform these product-specific checks: verify polarity and loop resistance, check fuses and terminal torque, prove input and fault states; document the final results.
