S-PT-1X2-24DC - Surge protection device

2880668

Surge protection in the IP67 screw-on module for measuring sensors, direct mounting with M20 x 1.5 outer thread, cable gland for the signal cable, two-stage protective circuit. HART-compatible.

Notes on operation When the bridge is disconnected, the shield connection is indirectly connected to the housing or reference potential.
