The 1756sc-CTR8 is a counter Input Module that is manufactured by Spectrum Control. The 1756sc-CTR8 features under the 1756 ControlLogix series and comes with 8 single ended counter input types. The module operates at a counter speed of 0 to 65 Hertz and has an isolation voltage of 2550 Volts DC. The 1756sc-CTR8 also features an input frequency of 1 to 65 Hertz with an input impedance of 24 kOhms. The module features a backplane current of 230 mA at 5 Volts maximum Voltage and has a minimum pulse time of 5.4 us. The power dissipation for the 1756sc-CTR8 is 4.8 Watts at the maximum. Spectrum Control builds licensed core technology input/output modules for the Rockwell Automation products.
The 1756sc-CTR8 features eight individual configured channels for voltage, current, thermocouple RTD, and resistance. It supports eight single-ended counters or a combination of input pairs for quadrature counters. The module also features simultaneous count and rate data that is available for each input with the rates of up to 65 Kilohertz. The 1756sc-CTR8 has an external counter enable lines that are available for dynamic counter control and also features the user definable scaling, limits, input control, and filters. Note that the 1756sc-CTR8 is designed for use exclusively on the Allen Bradley ControlLogix 1756 input/output rack systems. The module comes with AC and DC pulse information that comes from the external sensors and stores. It also comes with system timestamp of data and has a 64-bit system clock that places a time stamp on data transfer.
