The Crouse-Hinds series MTL IOP offers protection for both digital I/O and analog I/O. This is the most economical surge protection solution for I/O offered by our business. Its high packing density, high protection level and low price combine to make the IOP a value solution.

Overview

The Crouse-Hinds MTL IOP series delivers the most economical, high-density surge protection for both digital and analogue I/O loops. Combining a hybrid protection circuit rated at 20 kA with removable terminals and ultra-narrow widths, IOP modules minimize cabinet space while guaranteeing reliable defense against transients.
