VersaMax IC200MDD841 User Manual

VersaMax Mixed Discrete / High-Speed Counter Module
May 2011
Product Description
The VersaMax Mixed Discrete High-Speed Counter (HSC) module,
IC200MDD841, has twenty 24VDC positive-logic type inputs and twelve
positive-logic 24VDC 0.5Amp outputs.
In its default configuration, the module provides four Type A high-speed
counter inputs and outputs plus twelve standard inputs and eight
standard outputs.
Each counter provides direct processing of rapid pulse signals up to
80 KHz for industrial control applications such as velocity measurement,
material handling, and process control.

The module's inputs and outputs can be re-configured for a wide variety
of applications:
▪
The high-speed counter inputs can be set up as standard high-
speed inputs, as four type A counters, as two type A counters plus
one A-quad-B counter, or as one type A-quad-B counter with
homing capability.
▪
Four of the outputs can be configured as pulse-width modulated
(PWM), pulse train, ramping pulse train, or HSC outputs.
When configured for PWM operation, the frequency of each PWM
output is selectable in the range of 22Hz to 2 KHz. The duty cycle of
each PWM output can be set from 1 to 100% depending on the
frequency of the PWM output. See the Minimum % Duty Cycle vs. PWM
Output Frequency graph in the I/O Modules Manual.
When configured as pulse train or ramping pulse train outputs, the sum
of frequencies may be up to 5,000 pulses per second. Acceleration and
deceleration can be selected from 10 to 1,000,000 p/s
Power for module operation comes from the backplane. Output devices
must be powered by external voltage.
LED Indicators
Individual green field-side LEDs show the on/off status of each point.
The green FLD PWR LED indicates the presence of field power for the
DC outputs.
The OK LED indicates module status.
▪
On green indicates normal operation.
▪
Flashing green indicates boot mode or update
▪
On Amber indicates self diagnostic error
▪
Off indicates no 3.3V power present.

The number of points that can be on at the
same time depends on the surrounding air
temperature, voltage, and the type of carrier
on which the module is installed. To meet
thermal specifications, the module must be
installed on a horizontal DIN rail. There is
no thermal derating at 24VDC for
surrounding temperatures up to 42°C, or at
30VDC for temperatures up to 26°C. For
derating curves at higher temperatures, see
the I/O Modules User's Manual.
