IC200MDD851
Mixed Module, Output 12/24VDC Positive Logic Grouped
16 Points / Input 5/12VDC Pos/Neg Logic Grouped 16 Points
Discrete input/output module IC200MDD851 provides two groups of 8 discrete inputs and
one group of 16 discrete outputs. 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. For the
inputs to be compatible with TTL devices, the negative logic configuration should be used.
The outputs are positive or sourcing type outputs. They switch the loads to the positive
side of the DC supply and thus supply current to the loads.

Power for module operation comes from the backplane. Output loads must be powered by
an external source.
Intelligent processing for the module is performed by the CPU or NIU. The module
provides 4 bits of discrete input data and receives 8 bits of discrete output data.
LED Indicators
Individual green LEDs indicate the On/Off states of the output points and input points.
Backplane power must be present for LEDs to provide status of inputs. The output LEDs
are dependent on field power, but independent of load conditions.
The green FLD PWR LED is on when field power is applied to the module.
The green OK LEDs are on when backplane power is present to the module.
Configuration Parameters
The module’s basic input on/off response time is 0.25 ms. 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 0.25ms, 1.25ms, and 7.25ms respectively. The
default is 1.0ms filter time (total response time is 1.25ms).
