Brand: ABB

Product Series: System 800xA / S800 I/O System

Model: DI810 (Part Number: 3BSE008508R1)

Product Type: Digital Input Module (24 V DC 16-Channel Module)

ABB PLC Module DI810 3BSE008508R1

Technical Parameters:

Channel Configuration: Provides 16 digital input channels arranged in two isolated groups of 8 channels each.

Input Voltage Rating: Standard 24 V DC system operation (operational range from 15 V DC to 30 V DC).

Input Current: Typically 6 mA per channel at 24 V DC, complying with IEC 61131-2 Type 1 digital input standards.

Input Filter Time: Software-configurable digital input filtering (1 ms to 100 ms) to eliminate mechanical contact bounce and electrical line noise.

Galvanic Isolation: Optocoupler-based optical isolation between the low-voltage internal ModuleBus logic and field-side signal loops (up to 50 V continuous isolation).

Group Isolation: Group-to-group and group-to-backplane electrical isolation barriers to prevent ground loop propagation across the cabinet.

Power Dissipation: Low module power consumption (typically < 1.1 W) to minimize heat buildup inside compact enclosures.

Diagnostic Array: Front-panel LED indicator status display providing real-time visual tracking of module health, communication bus status, and individual input channel logic states (1 through 16).

Conformal Coating: Options include G3-compliant conformal coating on circuit board assemblies to resist corrosive atmospheric contaminants and humidity.

Mechanical & Mounting: Compact plug-in S800 module architecture designed for toolless snap-in mounting on standard S800 Module Termination Units (MTUs such as TU810, TU812, TU814, or TU830).

Industrial Sectors:

Chemical and Petrochemical Refining, Oil and Gas Processing, Power Generation and Utilities, Water and Wastewater Infrastructure, Pulp and Paper Processing, and Heavy Metallurgical Manufacturing.

Application Scenarios:

1. Field Switch and Sensor Telemetry: Installed within central DCS cabinets to collect real-time discrete status signals from field equipment, including pushbuttons, limit switches, proximity sensors, and auxiliary contacts.

2. Motor Control Center (MCC) Monitoring: Deployed in localized MCC cabinets to monitor motor starter states, running/stopped feedback, overload alarm contacts, and local selector switch positions.

3. Valve Position Status Aggregation: Integrated into plant floor junction boxes to capture open/close end-position limit switch confirmations from automated process control valves and dampers.

4. Distributed Marshalling Cabinet Expansion: Positioned inside remote S800 I/O enclosures to consolidate high-density discrete input channels, simplifying field cabling runs and streamlining connections back to the primary AC800M controller.
