The TURCK IM12-FI01-1SF-1R-0/24VDC is a frequency signal isolator designed for intrinsically safe applications in hazardous areas. It receives frequency or pulse signals from Ex zone sensors and provides two outputs: one solid-state NPN transistor and one relay. The device ensures safe signal separation through galvanic isolation and operates on 24 VDC. With DIN rail mounting, IP20-rated housing, and ATEX/IECEx compliance, this module is perfect for transferring pulses in flow measurement, rotation monitoring, and other automation processes in hazardous zones. Key Features: • Frequency signal isolator for Ex areas • Input: Frequency or pulse signal • Output 1: NPN transistor (solid-state) • Output 2: Relay contact • Intrinsically safe (Ex ia) – ATEX/IECEx compliant • Supply voltage: 24 VDC • Galvanic isolation between input and output • DIN rail mountable, IP20 housing • Ideal for flow, speed, and pulse transmission applications
