Product Info

The ABB DI821 3BSE008550R1 is an 8-channel digital input module designed for the S800 I/O system, specifically engineered to interface high-voltage field signals directly into the control system. It is used to acquire binary status signals to the controller for logic processing. Each of its eight channels features individually galvanic isolation, which prevents interference between channels and enhances system reliability in electrically noisy environments. The module is designed for flexible system integration and is compatible with multiple Module Termination Units, including TU811, TU813, TU831, TU839, and TU851.

l Channels: 8, current sinking

l Voltage Range: 230 V a.c. / 220 V d.c.

l Input Limits: 164–264 V a.c. / 175–275 V d.c.

l Filter Time: Selectable 2, 4, 8, 16 ms (5 ms / 28 ms analog delay)

l Compatibility: TU811, TU813, TU831, TU839, TU851

Product Applications

Process Automation:	Monitoring motor status feedback, valve position confirmation, and safety interlock verification from high-voltage field devices.
Power Generation & Distribution:	Interfacing with high-voltage switchgear status, circuit breaker auxiliary contacts, and substation control panels.
Manufacturing & Machine Control:	Acquiring on/off states from high-voltage relays, contactors, and emergency stop circuits in heavy machinery.
Discrete Control Systems:	Acting as the high-voltage input front-end for PLCs and DCS in alarm annunciation and data acquisition systems.
