The TB-SP9-KT upgrades the standard screw terminal blocks on SeaI/O modules with one complete set of spring clamp terminal blocks. The lever-style clamping mechanism requires no tools making field installation easy. The clamping mechanism also provides superior wire holding properties and automatically adjusts the spring tension on wire diameters from 16-28 AWG. The terminal block’s very tight friction design prevents accidental separation due to vibration.

The kit includes eight 5-position and one 6-position spring clamp terminal blocks for SeaI/O 410, 420, 430, 440, 450, 470, 530 and 540 modules. The removable terminal blocks have 3.5mm spacing between terminals and are keyed to prevent being inserted upside down.

Spring clamp and screw terminal blocks with 4-position, 5-position, or 6-position terminals are also available in packs of ten.
