Pepperl+Fuchs KFD2-SH-Ex1.T.OP | SIL 3 Isolated Switch Amplifier,

Pepperl+Fuchs KFD2-SH-Ex1.T.OP | Single-Channel Switch Amplifier – SIL 3, Relay & Voltage Output

Overview

The KFD2-SH-Ex1.T.OP (70100833) is a single-channel isolated switch amplifier from Pepperl+Fuchs, designed for intrinsic safety applications. It transfers signals from NAMUR sensors or mechanical contacts in hazardous areas to control systems in the safe area. The module supports SIL 3 functional safety and features line fault detection, a relay output, an active voltage output, and a fault indication output.

This unit is suitable for high-reliability process control and emergency shutdown (ESD) applications.
