S800 I/O / DIGITAL INPUT

ABB DI820 Digital Input Module

An eight-channel S800 I/O module for individually isolated 120 V AC and 110 V DC field inputs.

ABB DI820 is an S800 I/O digital input module for monitoring 120 V AC and 110 V DC field signals. The documented configuration provides eight individually galvanically isolated input channels with separate returns. ABB identifies article number 3BSE008512R1 and a rated isolation of 250 V. Compatible module termination units listed in the official System 800xA catalog include TU811, TU813 and TU831. The module is suited to installed process-control systems where high-voltage discrete status signals must be transferred through the S800 I/O architecture. Procurement review should verify the exact model, article number, field voltage, termination unit and system configuration.

Input Signal Path

01 / FIELD SIGNAL
120 V AC or 110 V DC discrete status reaches the selected channel.

02 / ISOLATED INPUT
Each of the eight channels is individually galvanically isolated.

03 / S800 I/O
Validated input status is integrated into the configured S800 I/O system.

Separate channel returns and individually isolated inputs support controlled integration of higher-voltage discrete field signals.

Typical Applications

AC status monitoring
Receiving 120 V AC equipment and process-status contacts.

DC status acquisition
Monitoring compatible 110 V DC field circuits.

Relay and contactor feedback
Bringing discrete operating states into an S800 I/O station.

Installed-system maintenance
Replacing a verified DI820 with matching article number and termination unit.

Compatibility and Revision Notice

Match model DI820 and article number 3BSE008512R1, the 120 V AC or 110 V DC field signal, channel wiring, separate returns, rated isolation, module termination unit and S800 I/O configuration. Do not apply specifications from DI821, DI825 or other similar modules.
