D1081D Interface Module for Hazardous Area Detector Signals

The D1081D interface module from G.M. International is a DIN-rail flammable liquid presence detector interface with two isolated independent channels. It connects 3-wire opto-electronic sensors or 3-wire proximity sensors located in a hazardous area to safe area control loads. Therefore, it is useful for chemical plants, oil and gas facilities, storage systems, loading skids, and process automation panels.

D1081D supports NPN or PNP transistor input configuration by DIP switch. It also supports NO or NC input logic and NO or NC optocoupled open-collector transistor output. In addition, each channel provides galvanic separation between input, output, and supply. This helps engineers build safer signal interfaces between field sensors and control systems.

D1081D Interface Module Features

This product accepts inputs from Zone 0 and Zone 20 applications, according to G.M. International product data. It provides two opto-isolated voltage-free transistor output signals. Also, the compact 22.5 mm DIN-rail housing saves space in control cabinets. The module uses plug-in screw terminal blocks, so technicians can wire and replace the unit efficiently during maintenance.
