Why Engineers Specify This Model
- Integrated Ethernet/IP — Native EtherNet/IP port enables direct connection to SCADA, HMI, and enterprise MES systems without an additional communication module.
- Relay Outputs for Mixed Loads — Relay contacts handle AC and DC loads up to 240V AC / 30V DC, eliminating external interposing relays in many panel designs.
- Dual Serial Ports — Channel 0 (RS-232) for programming/HMI; Channel 1 (RS-232/485) for Modbus RTU, DF1, or DH-485 device networks.
- LCD Display & Keypad — Onboard operator interface for status monitoring and minor parameter adjustments without a laptop on the plant floor.
- Compact Footprint — 24 I/O points in a single base unit reduces panel real estate and wiring complexity versus modular rack systems.
- Proven Ecosystem — Fully compatible with the 1762-series expansion library (analog, RTD, thermocouple, high-speed counter modules).
- Free Programming Software — RSLogix Micro Starter Lite is available at no cost, lowering total project cost for OEMs and integrators.

Application-Specific FAQ
Q: Can the 1762-L24BXB communicate with a Siemens HMI via Modbus RTU?
A: Yes. Channel 1 supports Modbus RTU (slave mode) via RS-485, making it compatible with most third-party HMI panels that support Modbus.
Q: How many expansion modules can I add to this base unit?
A: Up to 4 × 1762-series expansion modules, providing a maximum of 144 additional I/O points depending on module selection.
Q: Is this unit suitable for outdoor enclosures?
A: The 1762-L24BXB is rated IP20 and must be installed inside a sealed enclosure (minimum IP54) for outdoor or wash-down environments.
Q: What is the difference between 1762-L24BXB and 1762-L24BXBA?
A: The “A” suffix denotes a later hardware revision with minor firmware enhancements. Both are functionally equivalent for most applications. Contact us to confirm revision availability.
Q: Can I use Studio 5000 to program this controller?
A: No. The MicroLogix 1100 is programmed with RSLogix 500 (or the free Micro Starter Lite edition). Studio 5000 is for ControlLogix/CompactLogix families only.
Q: Do you provide programming or integration support?
A: We supply hardware. For programming services, we can refer you to certified Rockwell Automation system integrators in your region.
