Product Description

The TC-TBNH is a precision-engineered 20-pin terminal block assembly designed for Honeywell Experion PKS and PlantScape control systems. It serves as the primary interface between field wiring and I/O modules, providing a secure, vibration-resistant termination point for both digital and analog signals.

Built for industrial reliability, the TC-TBNH maintains signal integrity under high-vibration and electrically noisy conditions. Its compact, high-density design simplifies cabinet wiring, while the robust clamping mechanism prevents loose connections and wire fatigue. Ideal for both new installations and replacement of existing terminal blocks, it ensures a dependable electrical path for critical process data.

Frequently Asked Questions

Q: Can two wires be terminated in a single pin?
A: Yes. The TC-TBNH supports two-wire terminations provided the wires are 16–22 AWG, ensuring a secure connection for daisy-chained signals.

Q: Are special tools required for installation?
A: No. Standard compression-style screws allow installation using basic industrial screwdrivers without specialized crimping tools.
