IC200MDD841: Mixed Module, 24 V DC Positive Logic Input 20 Points / Output
12 Point / (4) High-speed Counter, PWM, or Pulse Train Configurable Points
Discrete I/O module IC200MDD841 has twenty 24 V DC positive-logic type inputs
and twelve positive-logic 24 V DC 0.5 A 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.

Q/I
I
When the module is installed in a VersaMax PLC, its 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 high speed counter 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 PWM Outputs section of this chapter for further details.
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.
