9000Ex-1 and 9000Ex-2
The 9000Ex-1 and 9000Ex-2 are designed to safely power and isolate 4–20 mA transmitters installed in hazardous areas. They provide a floating DC power supply to energize conventional or smart transmitters and safely repeat the transmitter signal to equipment located in the safe area.
The 9000Ex-1 is a single-channel model, while the 9000Ex-2 provides two channels. Both come in a compact 17.6 mm DIN-rail mounting design, making them suitable for automation panels where space is limited.
These modules offer high accuracy, low temperature drift, fast response, and strong galvanic isolation. They also support HART communication, allowing communication between devices in hazardous and safe areas when used with compatible 2-wire transmitters.
Typical applications include powering 2-wire transmitters in hazardous areas, isolating analog process signals, distributing signals in automation panels, and matching the impedance between transmitters and receiving instruments.
In short, the 9000Ex-1/2 acts as a safe interface between hazardous-area field transmitters and safe-area control systems, providing power, signal isolation, protection, and reliable signal transmission in one compact device.
