Pepperl+Fuchs KFD2‑EB2.R4A.B | 2‑Channel Encoder/High-Speed Pulse Evaluator | Intrinsically Safe
Overview
The KFD2‑EB2.R4A.B is an intrinsically safe, 2-channel high-speed pulse evaluator from Pepperl+Fuchs. Designed to convert field-side encoder or pulse signals into safe outputs for control systems, it accommodates sensors like incremental encoders or high-frequency pulse generators in hazardous (Ex) zones. This compact DIN-rail module delivers reliable, isolated signal processing in even the most demanding environments.
Key Features
-
Two independent pulse/encoder input channels
-
Intrinsically safe Ex ia input certification
-
Supports A/B pulse encoders and TTL-level signals
-
Loop-powered with isolated output pulses
-
Configurable quadrature or single-channel modes
-
DIN-rail mountable housing
-
LED diagnostics for signal and fault statuses
-
Overvoltage, surge and reverse polarity protection
