GE IC200MDL640E Discrete DC Input Module

FAQ

Q1: What is the GE Fanuc IC200MDL640E used for?
The IC200MDL640E is used to receive 24 VDC digital signals from field devices such as push buttons, proximity sensors, limit switches, and relay contacts, and transfer their status to a VersaMax PLC or Network Interface Unit (NIU).

Q2: How many input channels does the IC200MDL640E provide?
The module provides 16 discrete input channels, arranged in two groups of eight inputs. Each channel has an individual LED indicator for quick status monitoring.

Q3: What input voltage does the IC200MDL640E support?
The module is designed for 24 VDC nominal operation and accepts an input voltage range of 0–30 VDC. Inputs are recognized as ON between 15–30 VDC and OFF between 0–5 VDC.

Q4: Does the IC200MDL640E require an external power supply?
No. The IC200MDL640E is powered directly from the VersaMax backplane and does not require a separate external power supply for module operation.

Q5: What configurable filtering options are available?
The module supports selectable input filter times of 0 ms, 1 ms (default), and 7 ms, resulting in total response times of approximately 0.5 ms, 1.5 ms, and 7.5 ms. These settings help reduce false triggering caused by electrical noise or switch bounce.

Q6: What is the difference between the IC200MDL640E and earlier revisions?
Revision E introduced a UL94 V-0 flame-retardant plastic enclosure, improving fire resistance while preserving the same electrical specifications and compatibility as earlier IC200MDL640 modules.

Q7: Does the IC200MDL640E provide electrical isolation?
Yes. The module provides 250 VAC continuous isolation and 1500 VAC for one minute between the field wiring and PLC logic, as well as between input groups, helping improve system reliability in industrial environments.

Q8: What should be checked before replacing an IC200MDL640E module?
Before replacement, verify the VersaMax carrier compatibility, 24 VDC field wiring, positive/negative logic configuration, input filter settings, PLC hardware configuration, and terminal connections to ensure reliable operation after installation.
