ED1790 | HEDT300254R1 ABB EMBEDDED CONTROLLER

Application:

Valve Position Feedback: Reading limit switches on valves (e.g., fully open/fully closed) to confirm their position.

Safety Interlocks: Monitoring safety gates, emergency stop buttons, and safety-related switches to initiate protective actions.

Level Detection: Receiving signals from high/low level switches in tanks and vessels.

Pressure/Flow Switches: Monitoring alarm states from pressure or flow switches.

Equipment Alarms: Receiving alarm signals from various equipment (e.g., motor trip, high temperature switch).

Packaging Operations: Detecting box positions, lid presence, or conveyor jams.

Features:

• The 16 channels are typically divided into two isolated groups of 8 channels each.

• Each input channel has a dedicated LED on the front of the module.  
  

• In many S800 I/O configurations, the module supports hot-swapping, meaning it can be replaced without powering down the entire system, significantly reducing downtime during maintenance.

• Designed to accept standard industrial input voltages, typically 24 VDC, making it compatible with a wide range of field sensors and devices.

• 16 Digital Input Channels: Provides 16 independent channels to connect various field devices like limit switches, proximity sensors, push buttons, and contact closures.
