Allen-Bradley SLC500: 1747/1746 Series

3 products

The Allen-Bradley SLC 500 system, encompassing the 1747 and 1746 series, is a modular, small chassis-based family of programmable controllers, discrete, analog, and specialty I/O, and peripheral devices. It delivers power and flexibility with a wide range of communication configurations, features, and memory options. 

1747 Series

The 1747 series includes processors and communication modules that serve as the control and communication backbone of the SLC 500 system. Key components are:

  • Processors: SLC 5/01 to SLC 5/05 processors offer varying memory capacities and processing speeds to meet different application requirements. They support ladder logic programming and provide built-in communication ports for network integration.

  • Communication Modules: Modules such as the 1747-KE interface enable connectivity to various networks, including DH-485 and RS-232C, facilitating data exchange between the SLC 500 system and other devices.

1746 Series

The 1746 series comprises a wide range of I/O modules that interface with field devices to monitor and control industrial processes. Notable modules include:

  • Digital I/O Modules: Modules like the 1746-IA8 (AC input) and 1746-OW16 (relay output) handle discrete signals, enabling the system to process on/off inputs and outputs.

  • Analog I/O Modules: Modules such as the 1746-NI4 (analog input) and 1746-NO4I (analog output) process variable signals, allowing for precise monitoring and control of parameters like temperature, pressure, and flow.

  • Specialty Modules: Modules including the 1746-HSCE (high-speed counter) and 1746-BAS (BASIC module) provide specialized functions to meet specific application needs.

System Integration and Compatibility

The SLC 500 system is designed for seamless integration within industrial environments:

  • Modular Architecture: Its modular design allows for flexible system configuration and easy expansion, accommodating up to 30 I/O modules across multiple chassis.

  • Communication Support: The system supports various communication protocols, including DH-485, DH+, and Ethernet/IP (with appropriate modules), facilitating integration with other systems and devices.

  • Programming Software: Utilizes RSLogix 500 software for ladder logic programming, providing a user-friendly interface for system development and maintenance.
