ABB Digital Input Module | 3BSE022360R1 DI802

Product Description

Configured for 120 V digital signal acquisition in an ABB I/O system, the ABB 3BSE022360R1 (DI802 Digital Input Module) provides eight individually galvanically isolated input channels for discrete field signals.

Hardware Specifications

Galvanically Isolated Digital Input Architecture

The DI802 provides eight discrete input channels with individual galvanic isolation. Each channel receives a digital field signal and transfers the input state to the I/O processing system without a direct conductive connection between the isolated channel circuits.

The module uses a DI channel architecture with eight inputs. The specified input level is 120 V. Therefore, field wiring should match the module's specified voltage class and the electrical requirements of the connected circuit.

The individual isolation also separates channel-side electrical potentials. Consequently, installation should maintain the intended isolation between field circuits and avoid wiring practices that create unintended common connections.

Frequently Asked Questions

Q: How many digital input channels does the DI802 provide?
A: The DI802 provides 8 digital input channels.

Q: Are the DI802 input channels galvanically isolated from each other?
A: Yes. ABB specifies the channels as individually galvanically isolated.

Q: What input voltage does the DI802 use?
A: The provided product data specifies a 120 V digital input configuration.

Field Installation Guidelines

• Verify the module identification and terminal assignment before connecting field wiring.
• Confirm that the external digital signals match the specified 120 V input configuration.
• Keep field wiring separated from circuits with incompatible voltage levels.
• Maintain the intended channel-to-channel isolation during installation. Do not introduce external common connections that bypass the isolation arrangement.
• Route signal wiring away from high-current conductors where practical to reduce electromagnetic interference.
• Apply appropriate protective earthing and cabinet wiring practices according to the installation requirements of the complete ABB I/O system.
• Inspect terminal connections for correct polarity, conductor seating, and mechanical tightness before energizing the circuit.
• Do not apply operating or power-consumption values that are not confirmed by the applicable ABB hardware documentation.
