Selection Guide
Use the following criteria to confirm the DI814 is the right module for your application:
- Signal Type: Do you need to read discrete ON/OFF signals (limit switches, pushbuttons, relay contacts, proximity sensors)? → DI814 ✓
- Voltage Level: Are your field devices 24 V DC? → DI814 ✓ | If 120 V AC → consider DI821
- Channel Count: Do you need 8 channels per module? → DI814 ✓ | If 16 channels → consider DI820 or DI830
- HART Support: Not required for digital inputs — DI814 is appropriate
- Controller Platform: ABB AC 800M with S800 I/O bus? → DI814 ✓
- Redundancy: For redundant I/O, pair with TB840A carrier and CI840 communication interface
- Environment: Standard industrial (0–55 °C, non-condensing) → DI814 ✓ | Extreme environments may require additional enclosure protection

Replacement & Compatibility FAQ
Q: Can I replace DI814 with DI810 directly?
A: Yes, in most cases. Both are 8-channel 24 V DC DI modules on the S800 bus. Verify the carrier module and I/O address configuration in Control Builder M before swapping.
Q: Is DI814 compatible with ABB 800xA?
A: Yes. The AC 800M controller running S800 I/O (including DI814) integrates fully with ABB 800xA as the supervisory DCS layer.
Q: Can DI814 be used with third-party PLCs?
A: No. DI814 communicates exclusively via the ABB Modulebus protocol. Integration with Siemens, Rockwell, or other PLCs requires a gateway or migration to a compatible I/O platform.
Q: What is the difference between DI814 and DI820?
A: DI820 offers 16 channels vs. DI814’s 8 channels. Both operate at 24 V DC on the S800 bus. Choose DI820 when higher I/O density is needed to reduce module count.
Q: Do you supply new, refurbished, or used units?
A: We supply new-in-box (NIB), factory-refurbished (FR), and tested-used (TU) units. Condition is clearly stated on each listing. Contact us to confirm current stock condition.
Q: Can you provide a certificate of conformity or test report?
A: Yes. Documentation packages including CoC, test reports, and ABB datasheets are available upon request for quality-critical procurement.
