The TURCK IM1-231EX-R is a dual-channel isolating switching amplifier designed for safely transferring signals from NAMUR sensors located in Ex zones to safe areas. Each channel processes one NAMUR input and provides a corresponding relay output. The device features built-in diagnostics for wire break and short-circuit detection, supporting high operational safety. With its DIN rail mount design and ATEX compliance, the IM1-231EX-R is ideal for signal interface applications in the chemical, pharmaceutical, and oil & gas industries. Key Features: • 2-channel isolating switching amplifier • Input type: NAMUR sensors (intrinsically safe) • Output: 2 relay contacts • Diagnostic functions: wire break / short circuit • ATEX-compliant for hazardous areas (Ex ia) • Power supply: 20…30 VDC • DIN rail mounting • Ideal for safe signal transfer in process automation
