Description
Product Overview
ABB 086345-004 is a multi-loop process control circuit board designed for ABB early-generation DCS platforms. Moreover, it adopts backplane plug-in installation inside the controller chassis. This board supports multiple independent control loops at the same time, and it receives analog and digital field signals to complete closed-loop adjustment. It carries built-in signal conditioning and isolation circuits, so it can filter industrial interference and maintain steady control performance. It belongs to discontinued original spare hardware, and it mainly supports maintenance of existing running process control cabinets.
Core Features
- Model: 086345-004, ABB multi-loop process control board
- Backplane plug-in structure for easy mounting inside matched DCS racks
- Supports independent multi-loop closed-loop control for process variables
- Integrated signal isolation and filtering circuits to resist electromagnetic noise
- Compatible with common signal types including RTD, thermocouple and 4-20mA
