ABB DI620 3BHT300002R1 Digital Input Modules

The ABB DI620 (Product ID: 3BHT300002R1), also cataloged as the DI620 Digital Input Module, operates as a dedicated hardware component for binary status monitoring and discrete signal acquisition within System 800xA control platforms.

Hardware Specifications

Backplane Bus Communication Velocity & I/O Density Scaling

The module delivers high-density discrete signal acquisition across 32 binary channels operating at 24 VDC nominal potential. Deterministic backplane bus communication velocity and firmware flash compatibility allow real-time status updates to the main processor without latency, while onboard optical isolation isolates external field wiring noise from sensitive control backplane electronics.

Frequently Asked Questions

Q: What is the channel density and signal voltage rating for the ABB DI620 module?

A: The ABB DI620 features 32 discrete digital input channels designed to process standard 24 VDC binary field signals.

Q: What are the physical dimensions and net weight of the DI620 module?

A: The module measures 40 mm in width, 273 mm in height, and 252 mm in depth, with a total net weight of 1.17 kg.

Field Installation Guidelines

Verify that system power is completely isolated before inserting or removing the module from the subrack to avoid electrical contacts arcing. Field wiring for the 24 VDC digital input channels must utilize shielded cables routed in separate wireways away from high-voltage AC lines to prevent capacitive interference. Cable shields must be terminated at a single-point earth ground, and terminal block mounting screws must be secured according to standard installation torque specifications.
