4-20 mA HART Loop Protocol & Channel-to-Channel Isolation
The FC-SDI-1624 utilizes galvanically isolated channel circuitry to decouple 24 VDC discrete field input loops from internal backplane processing logic. This physical and electrical isolation blocks high-voltage surges, field-side ground loops, and common-mode noise from propagating across the chassis backplane. Preventing ground potential shifts preserves internal signal integrity when installed adjacent to analog processing cards executing 4-20 mA HART instrumentation loops.
Frequently Asked Questions
Q: What power levels are required to operate the FC-SDI-1624 digital input channels?
A: The module operates on a nominal 24 VDC supply voltage with a current draw of 110 mA.
Q: How does the module protect system logic from field-side electrical interference?
A: Integrated channel-to-channel and bus isolation barriers prevent field voltage spikes and ground loops from affecting backplane communication or adjacent I/O modules.
Field Installation Guidelines
- Power down the I/O rack or follow safety maintenance procedures before inserting the FC-SDI-1624 into its designated chassis slot.
- Align the module circuit board with the upper and lower guide rails, sliding it in until the backplane connectors fully seat and locking tabs engage.
- Verify that all 24 VDC field input wiring shields are terminated to the main enclosure protective earthing bar.
