MeloAuto-Trusted PLC & DCS Parts Supplier
Overview
The DI825 (Article Number: 3BSE036373R1) is an 8-channel digital input module designed for the S800 I/O system. It supports 125 V d.c. inputs, offering individually isolated channels. This module is equipped with current-limiting components, EMC protection, input state indication LEDs, and optical isolation barriers. Channels 1 and 8 can be used for voltage supervision, ensuring reliable field input power by monitoring voltages on channels 2-4 and 5-7.
Key Features & Benefits
- 8 Channels for 125 V d.c. inputs
- Individually isolated channels to ensure safety and reliability
- Voltage supervision for field input power via Channels 1 and 8
- Input status indicators for each channel
- Sequence of Event (SOE) functionality for precise event recording
- Signal filtering options for reducing noise (0-100 ms)
