The Ex i/Ex e relay module type 9177 is an automation solution for hazardous areas in Zone 1, 2, 21 and 22 and in safe areas and permits galvanically separated switching of intrinsically safe (Ex i) and non-intrinsically safe (non-Ex i) electrical circuits. Both Ex i and non-Ex i electrical circuits can be connected to its coil and contact connections. Thanks to the integrated fuse for the contact and coil circuit, additional integrated fuse is not necessary.
- Slim design – 12 mm width
- Choice of circuitry of coil and contact between Ex i or non-Ex i (Ex e)
- Integrated fuse for contact and coil circuit integrated
