IC200MDD842

Mixed Module, Output 24VDC Pos. Logic 0.5A Grouped w/ESCP 16 Points

/ Input 24VDC Pos/Neg Logic Grouped 16 Points

Discrete input/output module IC200MDD842 provides one group of 16 discrete outputs
w/ESCP and two groups of 8 discrete inputs. The outputs are positive or sourcing type
outputs. Each point has electronic over-current protection and short circuit protection, and
generates a fault if either condition exists. They switch the loads to the positive side of the DC
supply and thus supply current to the loads. Inputs in each group can be either positive logic
inputs that receive current from input devices and return the current on the common, or
negative-logic inputs that receive current from the common and return current to the input
device. Input devices are connected between the input terminals and common terminals.
Note: Negative-logic functionality requires module version IC200MDD842B or higher.
An external DC power supply must be provided to switch power to the loads. Intelligent
processing for this module is performed by the CPU or NIU. The module provides 16 bits
of discrete input data and receives 16 bits of discrete output data.
LED Indicators
Individual green LEDs indicate the on/off state of the output points and input points.
Operation of the output LEDs is dependent on field power, but independent of load
conditions. Individual amber LEDs indicate overload conditions on each output point. The
green FLD PWR LED is on when field power is applied to the module. The green OK
LED is on when backplane power is present to the module.
Configuration Parameters
The module's basic input on/off response time is 0.5ms. For some applications, it may be
preferable to add additional filtering to compensate for conditions such as noise spikes or
switch bounce. Input filter times of 0ms, 1.0ms, or 7.0ms are selectable via software
configuration, for total response times of 0.5ms, 1.5ms, and 7.5ms respectively. The default is
1.0ms filter time (total response time is 1.5ms).
Diagnostics
The module reports the presence of any overloaded points to the system on a per-module
basis. Amber LEDs indicate the overload conditions on a per-point basis. Once the
overload condition is removed, normal operation is resumed.
