The 1746sc-CTR8 is an 8-channel single-ended input module that has been designed and manufactured by the Spectrum Corporation. It also comes with quadrature encoding. It has a counter speed of up to 50 KiloHertz and it comes with an input impedance of 25 Kilo Ohms. This module works perfectly with different devices that are manufactured by Rockwell Automation. The backplane’s maximum current rating is 225 milliamps for a 5 Volts DC power supply. The 1746sc-CTR8 dissipates 1.75 Watts of power. This module is widely used as a general-purpose meter for flowmeter applications which require 8 input channels and a high level of accuracy. It has a channel update time of 4 milliseconds. The channel-to-backplane isolation rating for this module is 1000 Volts DC.

The 1746sc-CTR8 offers high-resolution user-configurable settings, temperature compensation, and programmable safe states. It comes with high channel density for lower resource consumption. It uses support from Rockwell Automation. The device is certified with various standard ratings like the UL, cUL, ISA, and the ANSI ratings for electromagnetic compatibility. This module comes with programmable counter functions like start, stop, reset, and preset. It also has an additional alarm and zero flags. The filters that it has can be selected from a range between 15 and 30 and 50 KiloHertz. The 1746sc-CTR8 offers high levels of accuracy and reliability. It is a cost-effective solution because it has a high channel density to reduce the consumption of resources. It is a robust device with a state of the art performance level. The 1746sc-CTR8 uses Allen-Bradley technology and it performs efficiently like Allen-Bradley devices.
