The IC200MDD851 is a discrete I/O module from GE Fanuc Automation. It belongs to the Versamax product line. This module provides 16 discrete output points arranged in two groups of eight. Therefore, it suits compact control panels with mixed signal needs. Engineers use it for flexible logic interfacing.
The IC200MDD851 offers versatile input and output configurations. Each group contains either positive or negative logic inputs. Positive inputs draw current from the input devices and return it to the common. Negative logic inputs do the reverse, receiving current from the common and returning it to the input device. This design increases functional flexibility.
Input devices connect between the input and common terminals. When compatibility with TTL devices is required, users should apply the negative logic connection. Meanwhile, the outputs work as positive or sourcing types. These outputs switch loads to a positive DC supply and deliver current to the loads.
The module handles 4 bits of discrete input data. It also receives 8 bits of discrete output data. A Central Processing Unit or Network Interface Unit performs intelligent processing for the IC200MDD851. Additionally, the backplane of the PLC powers the module, while output loads use an external power source.
The IC200MDD851 includes LED indicators for input and output status. These LEDs show on and off conditions for the connected sources. However, the backplane power must be active to display these conditions. The output LED indicators depend on field power rather than load status. Besides, a green power LED turns on when the module receives field power. Therefore, technicians can quickly locate power disruptions in different areas.
The IC200MDD851 uses a compact module format for Versamax racks. It relies on backplane power for internal operation. Field power feeds the output loads separately. This separation supports stable performance in industrial cabinets.
First, mount the IC200MDD851 in a Versamax rack. Next, connect input devices between the input and common terminals. Then, choose positive or negative logic based on your device type. For TTL devices, select the negative logic connection.
After that, wire the output loads to an external power source. Ensure the backplane power is active for LED indication. Finally, verify the green power LED turns on when field power is present. Check input and output LEDs to confirm proper signal flow.
