PRODUCT DESCRIPTION
Key Technical Features
-
Ultimate Space & Cost Efficiency
A single 14mm-wide module handles 32 digital inputs, doing the work of four traditional 8-channel modules. This saves 75% of your DIN-rail space and drastically lowers the cost-per-channel.
-
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.
-
Industrial Opto-Isolation
Equipped with high-speed optocoupler isolation between the field input signals and the internal backplane bus, protecting your control core from electrical noise, surges, and EMI.
