WG 21

The WG 21 provides protective separation and high isolation between the input, output, and power supply. The high supply voltage, the good hazardous-area ratings, and the broad-range power supply allow for universal use. Cables up to 1400 m in length can be used without any problems. Thanks to a new transformer-based transmission technique, the WG 21 achieves an extraordinarily high transmission accuracy for hazardous-area applications. The encapsulation provides maximum operating safety, long-term stability, and disruptive strength even under extreme ambient conditions.
