B-DO Intrinsically safe barrier for digital outputs

B-DO 4-channel intrinsically safe barrier for digital outputs
Protection degree IP65
Atex approval present
Signal output Digital
Inputs Digital

B-DO is a digital output separator that serves as a safety barrier between intrinsically safe circuits (devices in potentially explosive areas) and external circuits. Facilitates the connection of conventional devices to intrinsically safe correctors and recorders.

Main features:

• Separator for up to 4 digital outputs for ELCOR, ELCORplus, ELCORplus indexer, DATCOM and DATCOMplus correctors.

• Output type: open collector.

• Mounting: on 35 mm DIN rail.

• Supply voltage: 12V DC.

• Operating temperature: -40 to +70°C.

The device isolates up to four digital signals, connecting input terminals DI1 to DI4 to output terminals DO1 to DO4 across a safety barrier. It also includes the U+ and GND terminals for the safe internal power supply required for the digital output circuits in the speller/recorder, galvanically isolated from the other speller circuits. The electrical parameters of the signals remain unchanged after passing through the separator.
