Select I/O – DIS820

Select I/O is an Ethernet networked, single channel granular I/O system for the ABB Ability™ System 800xA automation platform. Select I/O helps decouple project tasks, minimizes the impact of late changes, and supports standardization of I/O cabinetry ensuring automation projects are delivered on time and under budget. A Signal Conditioning Module (SCM) performs the necessary signal conditioning and powering of the connected field device for one I/O channel.

The DIS820 is a Digital Input 120 V Signal Conditioning Module supporting 2/3/4-wire devices with Sequence of Events (SOE).

Özellikler ve Faydalar

  • Digital input for 2-wire, 3-wire and externally powered 4-wire field devices
  • Channel to channel galvanic isolation
  • Field power sourced from the power injection
  • Configurable software signal filter 0…100 ms
  • Diagnostics:
    • Fuse status supervision
    • Communication supervision
    • Internal power supervision
  • Sequence of Events (SoE)
  • DIS820 supports both Normally Open (NO) and Normally Closed (NC)
  • Single loop granularity – each SCM handles a single channel
  • Supports hot swap
  • Mechanical locking slider which turns off field device power and/or output before removal
  • Field disconnect function which can galvanically separate the field loop wiring from the SCM during commissioning and maintenance
  • Mechanical keying to prevent insertion of wrong module type after commissioning
  • 24V DC powered through Modulebus
  • Configurable through parameters
  • LED indicators on the SCM indicate the operational state of the module
