PRODUCT DESCRIPTION
Key Technical Features
-
Independent Power Supply Design
The CT-124D features a dedicated independent power supply for its field channels. This ensures stable and reliable power delivery to a massive array of sensors without overloading the backplane, significantly enhancing system safety and fault isolation.
-
Universal Sink/Source Compatibility (NPN/PNP)
Adapts perfectly to both active high (PNP/Source) and active low (NPN/Sink) field sensors simply by configuring the common (COM) terminal wiring, reducing the need for multiple module types.
-
Maximum Cabinet Space Savings
A single 14mm-wide module handles 32 digital inputs, effectively replacing four traditional 8-channel modules. This saves 75% of your DIN-rail space and drastically lowers the overall cost-per-channel.
