The TURCK FM-IM-3UR38X is a 3-channel isolating interface module engineered for transferring NAMUR sensor signals from Ex zones to safe control systems. Each channel provides a relay output corresponding to its sensor input and includes built-in diagnostics for wire break and short-circuit detection. The module ensures intrinsic safety (Ex ia) and is mounted on DIN rail for space-efficient installation in control cabinets. It is widely used in process industries requiring high-reliability signal isolation from hazardous areas. Key Features: • 3-channel interface for NAMUR sensors • Relay outputs for each input channel • Intrinsically safe signal transmission (Ex ia) • Diagnostic functions for fault monitoring • Designed for hazardous area applications (ATEX compliant) • DIN rail mounting • Operating voltage: typically 24 VDC • Ensures safe and isolated sensor signal transfer
