ABB DI802 | S800 I/O Digital Input Module – 3BSE022360R1

Description Product Introduction The ABB 3BSE022360R1 DI802 is an 8-channel digital input module from ABB’s S800 I/O family—the current-generation I/O system for System 800xA and AC 800M platforms. This module reads discrete signals from field devices like limit switches, pushbuttons, proximity sensors, and relay contacts. It’s the smaller sibling to the 16-channel DI801 and the 32-channel DI810, fitting applications where I/O density is lower but space is still at a premium. What distinguishes the ABB DI802 from the DI801 is the channel density and termination flexibility. The DI802 packs 8 inputs into a compact module, ideal for applications with limited I/O counts or where you need to distribute I/O closer to field devices. The module uses the same termination units as the DI801, so you can mix and match in the same rack. In my experience, the DI802 is the go-to module for small skids, packaged equipment, and applications where you need to minimize rack space. The “R1” suffix indicates the final production revision with improved transient protection and faster response time. Key Technical Specifications Parameter Specification Model ABB 3BSE022360R1 DI802 Series S800 I/O Module Type Digital Input Channels 8 (individually isolated in groups of 4) Input Voltage 24 VDC (18–30 VDC range) Input Current 6 mA per channel (typical) On-State Threshold > 15 VDC Off-State Threshold < 5 VDC Response Time < 1 ms (typical) Isolation 1500 VAC between field and logic Status Indication Per-channel LED (green), module OK LED Fault Detection Open-circuit, short-circuit (configurable) Power Consumption 1.5 W (from backplane) Operating Temp -40°C to 70°C Mounting S800 I/O rack (TU8xx termination units) Termination Via TU810, TU830, TU840, TU850 termination units Firmware / Software Versions & Upgrade Notes The ABB DI802 contains no user-upgradable firmware. The module’s behavior is determined by its hardware revision and the controller’s configuration. Minimum controller firmware: AC 800M firmware version 5.0 or later. Version 4.x supports the module but with limited diagnostic features. Software compatibility: Control Builder M Professional version 5.0 or later, or System 800xA Engineering version 6.0 or later. Hardware note: The DI802 is hardware-based—no configuration parameters on the module itself. All channel configuration (filter time, fault detection) is set in the controller’s I/O configuration. No field upgrade: You cannot upgrade the DI802 to a different module via firmware. The hardware revision is fixed. ⚠️ Field note: The ABB DI802 has a configurable input filter time (set in the controller configuration). The default is 2 ms. For high-speed applications (like encoder counting), you can set it to 0 ms. But at 0 ms, contact bounce will cause multiple counts. Use the faster setting only with clean, solid-state signals. Compatibility & Replacement Matrix Original Model Replacement Model Compatibility Level Key Notes ABB DI801 (16-channel) ABB 3BSE022360R1 DI802 Needs adaptation DI801 has 16 channels, DI802 has 8. Wiring is different—you’ll need to re-terminate field wires. Not a direct swap. ABB DI802 (original) ABB 3BSE022360R1 DI802 Drop-in Direct replacement. Any DI802 revision is interchangeable. ABB DI803 (8-channel, 48 VDC) ABB 3BSE022360R1 DI802 Not compatible DI803 is for 48 VDC systems. DI802 is 24 VDC. Do not swap. ABB DI810 (32-channel) ABB 3BSE022360R1 DI802 Needs adaptation Different channel count, different termination units. Not a direct swap. ABB S500 DI501 (older) ABB 3BSE022360R1 DI802 Incompatible Different rack system. Requires new termination units. Frequently Asked Questions Q: What termination unit (TU) works with this module? The ABB DI802 mounts on any S800 I/O termination unit designed for 8-channel modules. Common options: TU810: Standard termination unit (screw terminals) TU830: With current limiting and HART filtering (though DI802 is digital, so TU810 is usually sufficient) TU840: With enhanced diagnostics TU850: With spring terminals The TU810 is the most common choice for digital input applications. Q: How do I wire the inputs? The ABB DI802 requires 24 VDC field power on the termination unit. Inputs are configured as sinking (NPN) or sourcing (PNP) depending on the termination unit wiring. Typically, you connect the 24 VDC supply to the common terminal, and the field device switches the input to common. Check the termination unit manual for the specific wiring diagram. Q: Can I use this module with 120 VAC inputs? No. The ABB DI802 is rated for 24 VDC only. For 120 VAC inputs, use the DI811 (120 VAC input module) or an interposing relay. Q: My inputs are reading incorrectly. What should I check? First, verify the input voltage at the termination unit. The ABB DI802 needs 18–30 VDC on the input common. If the voltage is correct, check the field device by shorting the input terminal to the common—the input LED should light. If it doesn’t, the termination unit or module may have failed. Also check the configuration in Control Builder—if the input is configured as “inverted,” a closed contact will read as OFF. Q: Does this module support hot swap? Yes. The S800 I/O system supports hot swapping. You can remove and insert the ABB DI802 while the system is running. The controller will detect the module and resume I/O scanning within a few seconds. Q: What’s the difference between DI802 and DI801? DI801 has 16 channels; DI802 has 8 channels. Both use the same termination units (TU810, etc.), but the DI802 occupies the same physical slot width. The DI802 is often used for applications where you need fewer inputs but want to keep the module count low for future expansion. Q: How do I configure the input filter time? In Control Builder or System 800xA Engineering, select the ABB DI802 in the hardware configuration. Under the channel properties, set the “Input Filter” parameter. Options are typically 0 ms, 2 ms, 5 ms, 10 ms. Choose based on the application—longer filters reject noise, shorter filters allow faster response. Q: What’s the fault detection capability? The ABB DI802 can detect open-circuit and short-circuit conditions on the input wiring if configured. In the controller configuration, enable “Open-circuit detection” and set the threshold. When enabled, the module reports a fault if the input current is below a certain level when the input is supposed to be ON. This is useful for monitoring safety circuits and critical sensors. 、 3HNE00421-1 1C31122G01 KPS-600/20-ESC DCS AN16GNOA AN56KNOA DCS IC754VGI06STD PLCDCS IC697PWR724 PLC Email: [email protected] Phone: 86 15340683922 Sales:Wu Jiedong Our products are guaranteed for 1 year, with new and original production stopped and imported spare parts.
