CWMICRO:HSC Product Data Sheet D301676X012 August 2013 ControlWave® Micro High-Speed/Low-Speed Counter Input Module The High-Speed/Low-Speed Counter Input (HSC) module provides the ControlWave Micro with four inputs used for measuring high-speed or low-speed pulse inputs. Each of the four HSC module inputs may be individually configured as either a 10 KHz (highspeed) or 300 Hz (low-speed) input. Field inputs are internally sourced dry contact inputs, typically from turbine meter and other mechanical contacts. Contact wetting is selectable as 2.2 mA (suitable for most applications) or 200 µA (for low power consumption applications). The selection of high-speed or low-speed inputs sets the appropriate input filter to allow high-frequency inputs or to minimize contact bounce from low-frequency mechanical contact inputs. Inputs may be converted to frequency or totalized counts using the ControlWave Designer High Speed Counter Function Block. Light-emitting diodes (LEDs) indicate the current status for each channel of the module. All I/O modules have surge protection that meets C37.90-1978 and IEC 801-5 specifications. Local or Remote Terminations The HSC module is available factory configured for either local terminations that consist of two 10-point terminal block assemblies or remote terminations that consist of two 14-pin mass termination headers. Terminations are pluggable and accept a maximum wire size of 14 AWG (American Wire Gauge). Remote terminations provide a convenient alternative to the standard direct connect termination. Remote terminations allow a concentration of electrical connections from one or more controllers to be located in a single area, such as the rear of a 19-inch cabinet. For more information on remote terminations, refer to Product Data Sheet CWMICRO.
