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.
