Technical Specifications

Installation Guidelines

• Mounting: The controller can be mounted on a DIN rail or directly to a panel. Ensure adequate clearance around the unit to allow for proper ventilation and heat dissipation.
• Wiring: Use an isolating transformer for AC power supply. Connect 0V DC to the neutral terminal and use the provided 24V DC user power terminal for field devices.
• Environmental: Keep the protective debris strip on the top of the controller during installation to prevent foreign material from entering the unit.
• Safety: Always disconnect all power sources before inserting or removing the controller or any expansion modules.
• Programming: Requires RSLogix 500 software (version 8.1 or higher recommended) for configuration and logic development.
