The TURCK IM31-12EX-I is a 2-channel isolating signal converter designed for use with 2-wire transmitters operating in hazardous areas (Ex zones). It accepts analog current signals (typically 4–20 mA) from field instruments and transmits them to the safe zone with full galvanic isolation. This device ensures reliable signal conditioning and electrical safety in process control systems. Housed in a slim DIN rail mount enclosure, the IM31-12EX-I is ideal for use in petrochemical plants, water treatment facilities, and other process industries where intrinsic safety is required. Key Features: • 2-channel signal isolator for 4–20 mA current loops • Suitable for use with 2-wire transmitters in Ex areas • Intrinsically safe (Ex ia) input circuits • Galvanic isolation between input, output, and supply • DIN rail mounting design • High signal accuracy and long-term stability • Ideal for process automation in hazardous zones
