Overview
The Allen-Bradley 1746-HSCE2 is a multi-channel high-speed counter input module designed for the SLC 500 family of controllers. The 1746-HSCE2 is compatible with all SLC 500 CPU modules, and is an intelligent module that is capable of counting in both directions. This module delivers real-time pulse counting and position feedback for demanding motion-control, packaging, and material-handling applications.
Key Features
- Supports up to four single-ended or two quadrature encoder inputs, making it ideal for motion control, packaging, and material handling systems
- Can count up to 1 MHz per channel, making it suitable for applications like position monitoring and totalizing
- Counter capability extends to 24 bits (±8,388,607) with operating class 1 or 4
- Eight (8) outputs composed of Four (4) virtual and Four (4) real 5-30 VDC sourcing outputs
- Input voltage range of 4.2V dc to 12V dc and 10V dc to 30V dc
- Input frequency response reaches to 1 M Hz and 0.7 to 1.6 milliseconds back-plane response time
