core functionality
ABB DI803 3BSE022362R1 module
DI803 is an 8-channel digital input module used to receive 230VAC switch signals from field devices such as switches, relay contacts, buttons, limit switches, etc., and transmit them to ABB 800XA series DCS controllers for logic processing.
In ABB’s I/O module system, DI803 forms a complete voltage coverage with other digital input modules in the same series:
Model Channel Number Voltage Level
DI801 16 channel 24VDC
DI802 8-channel 120VAC
DI803 8-channel 230VAC ✅
DI810 16 channel 24VDC
DI811 16 channel 48VDC
Main technical features
Wide voltage input: Supports 230VAC level, suitable for common AC control circuits in industrial sites
Channel isolation: Each input channel is isolated from each other, and a single channel failure will not affect other channels
Multiple protection: equipped with overvoltage protection, overcurrent protection, and overheating protection
Industrial grade design: sturdy casing, anti electromagnetic interference (EMC protection), suitable for harsh industrial environments
DIN rail installation: standard installation method for easy cabinet integration
High reliability: rigorously tested and verified, suitable for long-term continuous operation
Typical application scenarios
DCS control systems for industries such as electricity, petrochemicals, water treatment, metallurgy, etc
Receive on-site 230VAC switch/relay signals (such as motor start stop feedback, valve status, alarm contacts, etc.)
Sequential Logic Control of Industrial Production Lines
Used in conjunction with ABB PM802F, PM866A and other controllers
