1746-HSCE Allen Bradley SLC High Speed Module
The Allen-Bradley 1746-HSCE is a High-Speed counter module. This module is part of the SLC500 Programmable Logic Controller (PLC) platform. It features bidirectional counting and comes with inputs A, B and Z compatible with nominal signal voltages of 5VDC differential input and 0-5VDC single ended input with maximum input frequency of 50 kHz. It also has a limit switch input and Four (4) open collector outputs. It may be configured to operate in Range, Rat and Sequencer mode.
The 1746-HSCE features input A, B and Z with nominal input voltage of 5VDC for differential wiring and 0-5VDC for Single-ended wiring. It accepts a minimum pulse width of 10 µs duration with pulse separation of 4.5 µs. The accepted input frequencies of these input sets depend on the configured mode of the module. When operating as Sequencer mode, the compatible maximum input frequency is 50 kHz and 32,767kHz when operating in Range Rate mode. Additionally, the 1746-HSCE has a limit switch input with ON-state voltage range of 3.8-5.4VDC, 9.4-16.5VDC and 16.5-30VDC @ 5VDC, 12VDC and 24VDC nominal voltages, respectively.
The 1746-HSCE also has Four (4) open collector outputs which operate at voltage levels of 4.5 to 10V dc and (Switch 2 on) and 10 to 30V dc (Switch 2 off) with ON-state current ratings of 16 mA at 4.5V dc 40 mA at 10V dc and 40 mA at 10V dc 125 mA at 30V dc.
