The 750-439 features eight digital input channels with short circuit and wire-break diagnosis in each channel. The digital input module receives binary signals from sensors operating in hazardous environments of ATEX Zones 0/20 or 1/21, connecting to intrinsically safe NAMUR sensors, optocouplers, mechanical contacts and other actuating elements.

The module supplies connected sensors with a short-circuit protected operating voltage of 8.2 V. For each channel, the module detects sensor failures, such as wire-breaks or short circuits. Diagnostic messages and the status of each input channel are indicated via integrated green LEDs. A color change to red signals an open circuit or a short circuit.

Diagnostic messages can also be displayed via higher-level control system and configuration software. When monitoring mechanical contacts instead of NAMUR sensors, the wire-break or short-circuit diagnostic LED can be deactivated via process image.

Within the WAGO-I/O-SYSTEM 750, the 8-channel digital module can be installed in Zone 2 alongside standard automation components, saving time and money. No additional devices (e.g., Zener barriers or isolating amps) are required and high-channel density is provided in a compact capacity, saving valuable space in the control cabinet. Any configuration of the I/O module is possible within an intrinsically safe segment when configuring the fieldbus node.

The 24 mm wide 8-channel module is ATEX and IECEX certified. Ideal for a variety of hazardous industries including oil and gas, mining, shipboard control and distilleries, the 750-439 meets the needs of intrinsically safe digital applications.
