Channel-to-Channel Isolation & Dual-Redundant Signal Paths
The ATA4D-00 S2 terminal block maintains signal integrity across 16 field transmitter channels by integrating dual-redundant wiring paths directly onto its internal PCB backplane interface. Designed for seamless integration with FIO analog input modules, it provides channel-to-channel isolation and galvanic separation to shield sensitive processing circuits from field ground loops and electrical transients. The pressure clamp design ensures stable physical connection under industrial vibration while supporting 4-20 mA HART loop signal routing without attenuation.
Frequently Asked Questions
Q: Does the ATA4D-00 S2 require active power from the FIO baseplate to function?
A: No, the terminal block acts as a passive field connection interface, routing power and signals directly between the field instrumentation and the primary analog input module.
Q: What wire gauge is supported by the pressure clamp terminals on the ATA4D-00 S2?
A: The pressure clamp terminals accommodate solid or stranded copper field conductors ranging from 0.2 to 2.5 mm2 (AWG 24 to 12) without needing terminal crimping tools.
Field Installation Guidelines
- Confirm the main FIO module rack is isolated or follow local hot-swap authorization procedures prior to attaching the terminal block.
- Align the rear connector pins of the ATA4D-00 S2 precisely with the mating slot on the FIO baseplate to prevent pin bending.
- Tighten the top and bottom captive securing screws to anchor the terminal block firmly against vibration.
- Strip field conductor insulation to 8-10 mm, insert the bare wire into the pressure clamp, and release the tension lever to lock the wire in place.
- Secure all field cable shielding to the dedicated cabinet system ground bar to prevent noise coupling across 4-20 mA analog input loops.
