Product Introduction
The Yokogawa ATC5S-00 is a pressure-clamp terminal block designed for reliable wiring connections in industrial automation systems. Its spring-pressure design ensures stable electrical contact without the need for screw tightening, making it easier to install, maintain, and re-terminate. It is mainly used for connecting field signals to Yokogawa I/O modules in DCS and PLC systems.

FAQ
Q1. How does the clamp maintain stable contact?
A1. The spring applies constant pressure, compensating for vibration and thermal expansion.
Q2. Can stranded wires be used without ferrules?
A2. Yes, but ferrules are recommended for long-term reliability.
Q3. Does it affect HART signals?
A3. No, resistance is negligible and transparent to HART.
Q4. What is the withstand voltage?
A4. Typically 2.0 kVrms for 1 minute.
Q5. How many re-terminations are supported?
A5. The spring design tolerates multiple wiring cycles without losing pressure.
Q6. What is the recommended wire strip length?
A6. 8–10 mm.
Q7. Is the block suitable for intrinsically safe loops?
A7. Yes, provided the loop meets IS design rules.
Q8. Does it require torque tightening?
A8. No torque is needed; insertion force is sufficient.
Q9. How is polarity ensured?
A9. Clear labeling and keyed alignment prevent miswiring.
Q10. Can the block be used in high-vibration areas?
A10. Yes, the spring clamp design is vibration-resistant.
