+86 1535940827516-Channel 0/4-20 mA Safe Analog Input FTA - Honeywell Safety Manager
Honeywell FC-TSAI-1620M is the sixteen-channel safe analog input FTA used between 0/4-20 mA field transmitters and the FC-SAI-1620M module. It provides current-to-voltage conversion, transmitter power distribution and external-power monitoring.
The sixteen inputs are arranged as two groups of eight with common 0 V. Input range is 0 to 25 mA through 250 ohm +/-1% resistors, producing 0 to 4 VDC for the SAI module with 0.10% conversion accuracy.
FC-TSAI-1620M accepts redundant 30 VDC external feeders and uses 315 mA group fuses. Verify SICC cable, transmitter type, shielding, grounded 0 V, FC-TPSU-2430 supply and Safety Manager monitoring logic.
