Processor compatibility

Compatible with MicroLogix 1500 processors: 1764-LSP, 1764-LRP.

Note: The base unit itself does not contain a processor and needs to be installed separately.

Environmental requirements:

Operating temperature: 0°C to 55°C.

Storage temperature: -40°C to 85°C.

Working humidity: 5% to 95% (non-condensing).

Environment: Suitable for clean and dry industrial environments, the circuit does not exceed overvoltage category II.

Installation:

Supports panel mounting or DIN rail mounting, open housing (IP20 protection grade).

Certification:

Comply with CE, C-Tick, UL, c-UL, and Class I Division 2 hazardous location certifications.

Function

Embedded I/O: 16 24V DC inputs (8 high-speed 20 kHz inputs), supporting high-speed counting, encoder or fast sensor signal processing.

12 outputs: 6 relay outputs (2 isolated) supporting various voltage loads, 4 standard FET outputs and 2 fast FET outputs (20 kHz) supporting pulse sequence output (PTO), suitable for simple motion control.

Communication function:

Channel Port 0 supports DH485, DF1, Modbus RTU and ASCII protocols, and is suitable for communication with HMI, SCADA or other PLCS.

Ethernet communication can be supported through the 1764-LRP processor or expansion modules (such as 1761-NET-ENI).

Sensor power supply: Built-in 24V DC sensor power supply (400 mA, 400 µF capacitor), providing stable power supply for external sensors and reducing the demand for external power supply.

Modular design

It is slide-in assembled with the 1764-LSP or 1764-LRP processor module to form a complete PLC.

Supports Compact I/O expansion modules (such as 1769-IF8, 1769-OW8), expanding to 512 I/O points to enhance flexibility.

High-speed counting and motion control

Eight 20 kHz high-speed inputs support fast counting applications (such as encoders).

Two 20 kHz fast FET outputs support PTO, suitable for stepper motors or simple servo control.

Programming support:

The RSLogix 500 programming software is used, which supports ladder diagram logic and online editing.

It can be used in conjunction with 1764-DAT (Data Access Tool) for parameter configuration and status monitoring.

Reliability and Safety

Open shell (IP20) design, suitable for clean and dry industrial environments.

It provides overvoltage protection and should be installed by professionals to avoid proximity to high-voltage lines.

Compatibility

Seamlessly integrate with other components of the MicroLogix 1500 system (such as the processor and DAT) to simplify the system design.

Application scenarios

Machine control: It is used for small independent machines (such as packaging machines, conveyor belts, pumping stations), and controls stepper motors or actuators through high-speed input monitoring encoders or sensors and fast FET output.

Process control: Suitable for simple process automation (such as water treatment, HVAC), it controls pumps, valves or heaters through relay output.

Distributed control: Integrated with HMI or other PLCS via Channel Port 0 (DH485 or Modbus RTU), it is suitable for distributed control systems.

Manufacturing automation: Applied in industries such as food and beverage, and automotive parts manufacturing, it supports multi-point control by extending I/O.

Energy management: Used in energy monitoring and control systems, the relay output supports load switching, and the sensor power supply supports external monitoring devices.

Replacement and Maintenance: As spare parts for discontinued products, it is applicable to the maintenance of the existing MicroLogix 1500 system, but it is recommended to migrate to MicroLogix 1400 (such as 1766-L32BXB) for long-term support.
