Structural Characteristics:​

Narrow CX power module format for stacked installation

Front LCD, navigation keys and PWR LED

Rear PC/104 interface for CPU and system module connection

5-pin open power connector for 24 V DC input wiring

Working Principle:​

The module converts external 24 V DC into regulated internal bus power and distributes it over PC/104 to the CPU and expansion modules. The microcontroller-driven LCD and navigation switches present system status; NOVRAM stores values through power interruptions; the PWR LED reflects normal or short-circuit supply conditions.

Installation Requirements:​

Mount directly beneath or according to the CX10x0 CPU stack configuration

Use 24 V DC with a 4 A fuse or Class 2 compliant power supply for UL requirements

Tighten the 5-pin power connector to the specified wire size and torque

Ensure PC/104 mating without forced insertion

Usage Precautions:​

Check PWR LED behavior; red indication denotes short-circuit condition

Do not apply K-bus or E-bus terminals directly to CX1100-0001 because it has no bus coupler

Avoid moisture, condensation and conductive dust in the cabinet

Backup NOVRAM-relevant data before replacing the module
