The ABB DI821 is an 8-channel digital input module designed for the S800 I/O system, capable of handling both 230 V a.c. and d.c. inputs. This module provides robust performance and features essential for effective monitoring and control in industrial applications.
Features:
Model: DI821
Part Number: 3BSE008550R1
Input Channels: 8 channels for 230 V a.c./d.c. inputs.
AC Input Voltage Range: 164 to 264 V, with an input current of 11 mA at 230 V a.c.
DC Input Voltage Range: 175 to 275 V, with an input current of 1.6 mA at 220 V d.c.
Isolation: Each input channel is individually isolated.
Voltage Supervision: Channel 1 monitors channels 2-4; channel 8 monitors channels 5-7 for voltage supervision.
Error Indication: If the voltage on supervision channels disappears, error inputs are activated, and a Warning LED turns on.
ModuleBus Interface: Error signals can be communicated via the ModuleBus.
Status Indicators: Input state indication through LEDs.
Signal Filtering: Analog filtering with a response time of 6 ms for improved signal integrity.
Frequently Asked Questions (FAQs)
What is the primary function of the DI821 module?
The DI821 serves as a digital input module for monitoring various signals in industrial applications, compatible with the S800 I/O system.
What types of inputs does the DI821 support?
It supports both 230 V a.c. and d.c. inputs across 8 channels.
How is voltage supervision implemented in the DI821?
Channel 1 supervises channels 2-4, and channel 8 supervises channels 5-7. If the input voltage disappears, an error signal is generated.
What is the significance of individual isolation for each channel?
Individual isolation prevents faults in one channel from affecting the others, enhancing the reliability of the system.
