Product Description:

The DI890 3BSC690073R1 Digital Input Module has 8 channels. The module includes Intrinsic Safety protection components on each channel for connection to process equipment in hazardous areas without the need for additional external devices. Each channel is galvanically isolated from the power supply, ground, and each other. Intrinsically safe Proximity sensors or volt-free contacts can be powered and monitored by any channel.

The Proximity sensor should conform to the NAMUR standard and line faults can be detected without any additional external components. For line faults to be detected when using volt-free contacts, external resistors should be connected in series and in parallel to enable the state of the field circuit to be sensed by the input channel. All eight channels are galvanic isolated from the ModuleBus and power supply individually.

Application:

Oil and gas: Offshore drilling platforms, oil production plants and oil pipelines.
Chemical and petrochemical industry: Reactor areas of refineries, fertilizer plants or pharmaceutical factories.
Mining industry: Monitoring systems for mines where flammable and explosive gases accumulate.
Food processing and logistics: Warehouses and conveying systems with the risk of dust explosions.
