The IC200MDD843 integrates both digital inputs and relay outputs into a single compact module. GE Fanuc designed this unit for the VersaMax product line, targeting applications where space and cost matter. This module offers ten (10) input points and six (6) output points, providing a balanced I/O solution for many control tasks.
The input section accepts positive logic or sourcing signals, making it compatible with standard 24 VDC sensors and switches. Meanwhile, the output section uses robust relay contacts rated at 8 Amperes. Therefore, the GE Fanuc IC200MDD843 can directly drive small motors, solenoids, contactors, and indicator lamps without external interposing relays. This mixed architecture reduces module count and simplifies system configuration.
The IC200MDD843 features 10 inputs configured as sourcing or positive logic type. These inputs respond quickly and work seamlessly with most industrial proximity sensors and pushbuttons. On the output side, the module provides 6 relay outputs with silver alloy contacts. Each relay uses a fixed coil with a moving armature design, ensuring reliable switching over many cycles.
Output current capacity reaches 8 A per point, sufficient for many field devices. The maximum response speed for both input sensing and output switching is 10 ms, which suits most discrete control applications. For inductive loads, the switching frequency should not exceed 20 cycles per minute to preserve contact life.
Power for the module's internal logic comes from the VersaMax backplane. The maximum backplane current draw is 190 mA when all points are active. However, the load side requires an external power source, because the backplane cannot supply the high current needed for outputs. The module does not include internal snubbers, fuses, or channel-to-channel isolation. Users should add external protection devices when switching inductive or high-surge loads.
The GE Fanuc IC200MDD843 operates reliably across a wide temperature range. It functions normally from 0°C to 60°C and can survive storage from -40°C to 85°C. Humidity tolerance spans 5% to 95% non-condensing, allowing deployment in humid production areas.
Additionally, the module withstands vibration of 1G at 40 to 150 Hz and shock of 15G for 11 milliseconds. These mechanical ratings ensure stable performance even near compressors, presses, or other vibrating machinery. The module's physical dimensions measure 1.956 x 2.63 x 4.3 inches (excluding carrier height and connectors). It uses 18 Type A terminals for standard field wiring, plus an additional Type B terminal accessible through a shorting bar for auxiliary connections.
Installing the IC200MDD843 requires a VersaMax carrier or backplane. First, power down the entire system to avoid any electrical hazards. Then, slide the module into the chosen slot until the locking mechanism engages securely. Next, connect your field devices to the Type A terminal blocks. For inputs, wire your sourcing sensors with the common return to the designated reference terminal. For outputs, connect the load between the output contact and the external power supply.
Because the module lacks internal fuse protection, consider adding external fuses on each output circuit. For inductive DC loads, install a freewheeling diode across the load to suppress voltage spikes. For AC inductive loads, use an RC snubber network. These steps will significantly extend relay contact life. After completing all wiring, power on the system and test each point using your PLC programming software. The front-panel LEDs will indicate the status of each input and output, simplifying verification and troubleshooting.

1. What input types does the IC200MDD843 support?
The GE Fanuc IC200MDD843 accepts positive logic or sourcing inputs. This means the input turns on when a voltage (typically 24 VDC) applies to the terminal relative to the common return.
2. Can I switch both AC and DC loads with this module?
Yes. The relay outputs can handle both AC and DC loads up to their maximum ratings. However, you must add external protection for inductive loads to prevent contact damage.
3. Does this module provide isolation between channels?
No. The IC200MDD843 does not offer channel-to-channel isolation. Each output contact operates independently, but they share common isolation characteristics. Use external isolators if your application requires galvanic separation.
4. What is the maximum current draw from the backplane?
The module draws a maximum of 190 mA from the backplane when all 16 points are active. The output loads require a separate external power supply.
5. What are the physical dimensions of this module?
The module measures 1.956 x 2.63 x 4.3 inches (width x height x depth), excluding the carrier and connector height. It fits standard VersaMax carriers and racks.
