NEW TURCK SWITCHING AMPLIFIER SAFETY RELAY IM1-12EX-R 7541226
The TURCK IM1-12EX-R (Ident. No. 7541226) is a high-performance single-channel isolating switching amplifier for bridging intrinsically safe (Ex-zone) input signals with non-hazardous industrial environments. It is a vital safety barrier and has an inherently safe input circuit which works in conjunction with NAMUR sensors (to EN 60947-5-6) or potential free mechanical contacts in hazardous regions, including Zone 2 installations.
This module is designed with functional safety in mind and delivers full SIL 2 rated loop reliability, universal broad range power supply capabilities and active line monitoring for wire-breakage or short-circuit problems. Its two normally open (NO) relay outputs enable reliable galvanic isolation and signal duplication for critical marine, offshore and petrochemical process automation systems.

Key Features
- Dual Relay Outputs (NO) – Dual isolated relay outputs (Normally Open) provide a simple means of duplicating a signal or creating separate fault routes.
- Intrinsically Safe Ex Barrier Interfaces with NAMUR proximity switches and mechanical switches in explosive settings (Zone 2 approved).
- Enhanced line fault monitoring: Built-in detection of wire breaks and short circuits on the field side, with an on-board toggle switch to disable monitoring when utilising dry mechanical contacts.
- Universal Wide-Range Power Input: Operates perfectly on AC and DC current (20-250V) without the requirement for separate voltage specialised units in inventory.
Applications
- Marine & Offshore Systems: Monitoring hazardous-area equipment, ballast water control systems, tank levels and fuel line valve positions on commercial boats.
- Oil & Gas Processing: Sensor isolation for refineries, offshore drilling platforms and gas compressor stations – intrinsically safe
- Chemical Production: Safety interlocks and location indication routeing for explosive raw chemical mixing zones.
- Water & Wastewater Processing Flow control and limit switch feedback loops from deep wells or wet wells with flammable methane gas.
