GE IC200MDD845G Discrete Mixed I/O Module

FAQ

Q1: What is the GE Fanuc IC200MDD845G used for?
The IC200MDD845G is used in VersaMax PLC systems to collect 24 VDC digital input signals and control external devices through relay outputs. Typical applications include machine control, motor control, valve control, and industrial automation equipment.

Q2: How many input and output channels does the IC200MDD845G provide?
The module provides 24 total I/O points, including 16 digital inputs and 8 relay outputs.

Q3: What type of input signals does the IC200MDD845G support?
The input section supports 24 VDC positive logic inputs with an operating range of approximately 18–30 VDC. It can be connected to switches, sensors, proximity devices, and other DC field devices.

Q4: What type of outputs are available on the IC200MDD845G?
The module provides 8 Form A normally open relay contact outputs. Each relay output is individually isolated and can switch AC or DC loads within the specified ratings.

Q5: What is the maximum load current of the relay outputs?
Each relay output can handle up to 2.0 A for 5–265 VAC resistive loads and 2.0 A for 5–30 VDC resistive loads. For 31–125 VDC applications, the maximum current is reduced to 0.2 A.

Q6: Does the IC200MDD845G require an external power supply?
Yes. The module receives logic power from the VersaMax backplane, but an external field power supply is required for connected input devices and relay-controlled loads.

Q7: What is the difference between the IC200MDD845G and standard discrete modules?
The IC200MDD845G combines both input and output functions in one module, reducing rack space requirements compared with using separate input and output modules. It also provides isolated relay outputs for controlling higher-power devices.

Q8: What should be checked before replacing an IC200MDD845G module?
Before replacement, verify the VersaMax carrier compatibility, input voltage level, relay output load ratings, field wiring connections, external power supply, module addressing, and PLC configuration to ensure proper operation after installation.
