Technical Specifications

Installation Guidelines

• Ensure the controller is installed in a clean, dry environment with adequate ventilation to prevent overheating.
• Mount the unit on a standard DIN-rail or directly to a backplane using the provided mounting holes.
• Always disconnect power before performing any wiring or module installation to prevent electrical shock or damage.
• Ensure proper grounding of the chassis to minimize electromagnetic interference (EMI) and improve signal integrity.
• Use shielded cables for input and output signals, keeping them separate from high-voltage power lines.

FAQ

Q: Does this unit require an external power supply for the inputs?
A: The 1764-24BWA inputs are rated for 24V DC; you must provide a suitable 24V DC power source for the input devices.

Q: Can this unit be expanded with additional I/O?
A: Yes, the MicroLogix 1500 base units are designed to support expansion I/O modules to increase the total point count of the system.
