H2-CTRIO(2)
H2-CTRIO(2) Overview
The H2-CTRIO(2) Counter I/O (CTRIO) module is designed to accept high-speed pulse
input signals for counting or timing applications. This module also provides high-speed
pulse output signals for servo/stepper motor control, monitoring and alarming as well as other
discrete control functions.
The H2-CTRIO(2) module offers greater flexibility for applications which call for precise
counting or timing based on input events or for high-speed control output applications. They
can also be used for applications that call for a combination of both high-speed input and high-
speed output control functions.
The H2-CTRIO(2) module has its own internal microprocessor and operates asynchronously
with respect to the CPU. Therefore, the response time of the on-board outputs is based on
the module scan time, not the CPU’s scan time (unless the CPU is controlling the outputs
directly).
NOTE:
The H2-CTRIO module has been discontinued. Please use the H2-CTRIO2 modules as the
replacement. H2-CTRIO and H2-CTRIO modules have the same terminal block layout.
