Lockable industrial terminal assembly for control cabinet wiring. It establishes reliable electrical connection between field instruments and I/O modules, separates power lines and signal lines to reduce crosstalk. The locking mechanism prevents loose terminals caused by vibration. Built-in surge suppression protects backplane I/O boards from transient voltage damage.

Certification: CE, UL

Insulating plastic base, metal conductive contact strips, screw locking components, surge protection chip, marking label. Common faults: terminal loosening, contact oxidation, short circuit between adjacent channels, insulation aging.
