1746-HSCE
The 1746-HSCE is a high-speed counter module. The module is part of the SLC500 Programmable Logic Controller (PLC) platform. It has bidirectional counting and comes with inputs A, B, and Z, compatible with nominal signal voltages for 5VDC differential inputs and 0-5VDC single-ended inputs, with a maximum input frequency of 50 kHz. It also has a limit switch input and four (4) open collector outputs. It can be configured to operate in range, mouse, and sequencing modes.
The 1746-HSCE is used for bidirectional counting requirements, motion detection, accumulation, and other applications where high-speed discrete inputs need to be processed. This module is typically used for factory automation applications, but is highly suitable for process automation requirements. The high-speed counter module can be configured to operate in different modes, such as range mode, rate mode, and sequencer mode.
The 1746-HSCE has inputs A, B, and Z with nominal input voltages of 5VDC for differential wiring and 0-5VDC for single-ended wiring. It accepts a minimum pulse width of 10 μs and a pulse interval of 4.5 μs. The acceptable input frequency of these input sets depends on the configuration mode of the module. The maximum compatible input frequency is 50 kHz when operating in timing controller mode and 32,767kHz when operating in range rate mode. In addition, the 1746-HSCE has a limit switch input with on-state voltage ranges of 3.8-5.4VDC, 9.4-16.5VDC and 16.5-30VD@5VDC, 12VDC and 24VDC nominal voltages, respectively.
The 1746-HSCE also has four (4) collector open-circuit outputs that 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, 40 mA at 10V DC, and 125 mA at 30V DC.
For troubleshooting and diagnostics, it has built-in diagnostic leds, such as CPU failure leds, fault codes, error codes. It also has an internal status word that resides in the input data file. It is intended for use in industrial environments and must be installed in a NEMA grade housing.
