Turck 2 Channel Galvanic Barrier with Hart Communication 24V DC, IECEx/ATEX Certified IM33-22EX-HI/24VDC

Turck IM33-22EX-HI/24VDC is a two-channel galvanic barrier designed for safe signal processing and isolation in hazardous industrial environments. Engineered to IECEx and ATEX standards, this isolating transducer builds a robust 2.5 kV barrier between input and output circuits, preventing surge transmissions and ensuring safe, uninterrupted operation.

Its polycarbonate/ABS housing combines durability with compactness, measuring 110 mm in height and width and just 18 mm in depth, making it ideal for installations where space is a premium. The device supports Hart communication with a bi-directional interface allowing reliable simultaneous transmission and reception of analogue signals converted to electrical measurements.

This galvanic barrier is intended for DIN rail mounting and utilizes screw terminals for secure wiring. Eligible for use in Zone 2 hazardous locations, it supports the full operating temperature range from -25°C to +70°C while providing IP20 ingress protection, suitable for indoor industrial automation, power distribution, and medical equipment applications.

The device complies with TÜV 00 ATEX 1595 and TÜV 06 ATEX 552977 X certifications, also meeting SIL 2 standards as per EXIDA FMEDA analysis. The compact yet robust design weighs 146 grams, minimizing stress on mounting rails and panels.

Key features include complete galvanic isolation, compatibility with 2-wire active and passive and 3-wire transmitters, and support for HART handheld units. The unit also features removable screw-termination terminal blocks with a 2 mm test box for easy maintenance and testing. Its flame-resistant construction prevents flame spread by stopping burning within ten seconds or less during fire incidents.

Compact, durable polycarbonate/ABS housing dimensions 110 x 110 x 18 mm. IECEx and ATEX certified for hazardous area installations including SIL 2 rated safety integrity. Safe operating voltage 24 V DC and max safety voltage 250 V with 331 ohms safety current resistance.

Bi-directional HART communication interface supporting analogue signal transmission. Supports Zone 2, with operating temperature range from -25°C to +70°C and IP20 protection. Screw terminal wiring and DIN rail mounting facilitate installation and maintenance.

Lightweight design at 146 g reduces mounting load and enables versatile application. Flame resistant materials ensure compliance with fire safety standards and limit fire propagation.

Perfectly suited for industrial automation systems, hazardous power distribution plants, and other demanding electronic applications, the Turck IM33-22EX-HI/24VDC galvanic barrier enhances operational safety and communication reliability.
