Pepperl+Fuchs 132959 Switch Amplifier KFD2-SR2-EX1.W.LB

Pepperl+Fuchs 132959 KFD2-SR2-EX1.W.LB is a 1-channel isolated barrier for digital signal transfer between hazardous and safe areas. This isolated barrier accepts NAMUR sensor and dry contact input signals for industrial process control. The isolated barrier provides dual relay outputs and supports signal splitting for control system connection. The isolated barrier features compact DIN rail mounting and 20mm slim housing for cabinet installation.

Line fault detection is the core function of Pepperl+Fuchs 132959 KFD2-SR2-EX1.W.LB. Line fault detection monitors field wiring for wire breakage and short circuit conditions automatically. Reliable Line fault detection triggers LED indication and fault relay alarm once circuit defects appear. Configurable Line fault detection can be enabled or disabled according to site application requirements.

This unit delivers reliable intrinsic safety protection for explosive zone installations. intrinsic safety limits energy output to avoid ignition in hazardous atmospheres. Certified intrinsic safety complies with ATEX standards and supports Zone 0, 1, 2 field device connection. Valid intrinsic safety meets SIL 2 functional safety requirements for process automation systems.

Pepperl+Fuchs 132959 KFD2-SR2-EX1.W.LB runs on 19~30V DC power supply via power rail or screw terminals. It supports reversible operation mode, and fault status follows NAMUR NE44 standard. LED status indicators show working and fault status clearly. Widely used in oil & gas, chemical and pharmaceutical hazardous area control projects for digital switch signal processing.
