X-15s Eight Digital Input Expansion Module
5 Year Warranty

X-15s Eight Digital Input expansion module can be monitored over the internet with the X-600M controller.


The X-15s has eight optically-isolated digital inputs and is an expansion module for the X-600M controller. The X-15s' isolated inputs are suitable for industrial environments and allow the grounding system of the monitored equipment and the low voltage circuits of the X-15s to be electrically separate.

Internally the X-15s has a co-processor which provides enhanced features including: pulse counting, pulse duration, accumulated pulse time and frequency measurements. All 8-inputs have separate measurements.

One or more X-15s expansion modules can be connected to an X-600M controller with a ribbon cable. The ribbon cable provides both power and communications to the expansion modules.

Other expansion modules with different I/O combinations are also available.
