Information About 1761-L16BWA

The 1761-L16BWA is part of the MicroLogix 1000 family from Allen-Bradley, offering integrated power, memory, I/O, and communications in a single compact module. It operates on 85–264 VAC input, includes ten 24VDC digital inputs, one high-speed input, and six relay outputs supporting both AC and DC loads. The controller contains 1 KB of nonvolatile EEPROM memory, allowing it to retain user programs without a backup battery. Its RS-232 communication port supports DF1 Full Duplex, DF1 Half Duplex, Modbus RTU (slave), and—on later series revisions—DH-485 via an AIC interface. Designed for industrial reliability, it meets global certifications, supports up to 50,000 power cycles, and operates in temperatures up to 55 °C. The controller can be installed on DIN rail or panel mounts and is built to endure vibration and shock conditions typical of factory environments.

Key Features:

  • Integrated I/O: Ten DC inputs, one high-speed input, and six relay outputs for flexible control of AC and DC devices.
  • Wide Voltage Power Supply: Accepts 85–264 VAC at 47–63 Hz, suitable for global installations.
  • Nonvolatile Memory: 1 KB EEPROM preserves program data without a battery, supporting long-term reliability.
  • Versatile Communication: RS-232 port supports DF1, Modbus slave, and DH485 (via AIC module on later series).
  • Relay Output Capability: Relay channels support 5–125 VDC and 5–264 VAC loads.
  • Compact Design: Combines controller, I/O, and power supply in one enclosure for space-saving applications.
  • Industrial Durability: Rated for 0–55 °C, with vibration and shock specifications for reliable field use.
  • Flexible Mounting: Can be DIN-rail mounted or panel-mounted to fit various control cabinet layouts.

The 1761-L16BWA provides robust performance and essential control capabilities for smaller automation systems and OEM equipment.

Frequently Asked Questions about 1761-L16BWA
Question: What is the main function of the 1761-L16BWA controller?
Date Update:05/06/2025
Answer:

The 1761-L16BWA is a MicroLogix 1000 programmable logic controller (PLC) used for small automation tasks. It provides 16 I/O points (10 digital inputs and 6 relay outputs), suitable for discrete control applications. It is designed for use in standalone systems or as part of a larger network via RS-232 communication. The PLC can control motor starters, sensors, indicators, and other industrial components. Its compact design makes it ideal for space-constrained applications.

Question: What communication protocols and ports are available?
Date Update:05/06/2025
Answer:

The controller has an RS-232 communication port supporting the DF1 protocol. It enables connection to HMIs, SCADA systems, or programming stations. The port also supports automatic baud rate detection and full-duplex communication. Appropriate cables such as 1761-CBL-PM02 or 1761-CBL-HM02 are used for programming. This ensures easy integration into existing industrial networks.

Question: What is the temperature range for operation and storage?
Date Update:05/06/2025
Answer:

The operating temperature range is 0 to 55 °C when mounted horizontally, and 0 to 40 °C for vertical mounting. The storage temperature range is -40 to 85 °C. This makes the controller suitable for a wide range of industrial environments. The non-condensing humidity should be maintained between 5% and 95%. It also withstands vibration up to 2.5G during operation.

Question: Can the 1761-L16BWA be connected to an HMI or SCADA system?
Date Update:05/06/2025
Answer:

Yes, the RS-232 port enables integration with Human-Machine Interfaces (HMI) or Supervisory Control and Data Acquisition (SCADA) systems. Using the DF1 protocol, the controller can exchange real-time data with visualization panels. PanelView terminals or third-party HMIs can be connected directly. This makes it suitable for operator monitoring and control. Proper cable selection ensures communication stability.

Question: Is the 1761-L16BWA still being manufactured?
Date Update:05/06/2025
Answer:

No, the 1761-L16BWA is no longer in production. It was part of the legacy MicroLogix 1000 series and has been discontinued by Rockwell Automation. Spare units may still be available through surplus or third-party suppliers. Rockwell recommends migrating to the Micro800 or CompactLogix platforms. Migration tools are available to assist in conversion.
