Features:
- Sixteen current-limited 24 V DC terminations
- Two fused groups of eight channels
- Interface to redundant SDI-1624 modules
FS-TSDI-1624C provides current-limited field termination for sixteen Safety Manager inputs.
Current limit and circuit resistance must be evaluated with the field device and hazardous-area design.
FTA, SICC cable and redundant modules form one diagnostic chain.
The Honeywell FS-TSDI-1624C 16-Channel 24 V DC Current-Limited Safe Digital Input FTA is available for quotation and technical support from Apter Power.
