PLCAGE: 1746-HSCE Allen-Bradley PLC 1746 Positioning I/O Modules 1 count input (5V DC, 12V DC or 24V DC) 4 outputs(5V DC, 12V DC, or 24V DC) New
Features
The high-speed counter module is used in control applications where the ability to detect high-speed machine or process motion is critical. It has a 16-bit counter to accept bidirectional input pulse frequencies of up to 50 kHz from encoders and other high-speed switching devices. It has 4 open-collector (sink) outputs so that the control loop is closed on the module without going through I/O or program scan delays. The module has three modes of operation: range, rate, and sequencer. Typical applications include packaging, material handling, flow monitoring, cut-to-length, motor speed control, and machining.
