Product Overview
The ABB DI818 (3BSE069052R1) is a 32-channel digital input module designed for 24 V DC signals in the S800 I/O system. Moreover, it features two isolated groups of 16 channels each, providing enhanced safety and voltage supervision. This configuration ensures reliable signal acquisition even in demanding industrial environments.
In addition, built-in voltage supervision actively detects input drops and generates error signals for immediate operator awareness. Therefore, DI818 ensures high system reliability and consistent process monitoring.
Key Functional Highlights
- 32 Input Channels: Handles 24 V DC signals with current sinking capability.
- Two Isolated Groups: Each group of 16 channels is individually monitored for voltage and errors.
- Voltage Supervision: Continuously checks input voltage to improve system reliability.
- Signal Filtering: Selectable digital filter times (2, 4, 8, 16 ms) maintain signal integrity.
- Front-Panel Diagnostics: LEDs display fault, run, warning, and channel states.
- Marine & Industrial Certifications: Certified by ABS, BV, DNV, LR for demanding conditions.
Furthermore, these features make the module ideal for both new installations and retrofits, reducing maintenance efforts.
