GE Fanuc IC754VSI12CTD VersaMax Micro Discrete Input Module (12 Channel)

In stock

Product Overview:
The GE Fanuc IC754VSI12CTD is a 12-channel discrete (digital) input module for the VersaMax Micro PLC. The “CTD” suffix indicates this module supports both sourcing (PNP) and sinking (NPN) input configurations, or a specific thermocouple/discrete hybrid variant depending on the exact hardware revision. This module doubles the input density compared to the 6-channel version, making it ideal for applications with a high number of discrete sensors such as packaging machines, conveyor systems, and assembly lines.
