Allen-Bradley 1747-L541 SLC 5/04 Processor 16 KB

Product Overview

The Allen-Bradley 1747-L541 is a powerful SLC 5/04 processor. It belongs to the SLC 500 series. This module offers 16 KB of battery-backed RAM. It handles up to 4096 input and output points. The processor includes a built-in Data Highway Plus (DH+) channel. It also has an RS-232 port for flexible communication. This model supports extended messaging and high-speed data transfer. The program scan time is 0.9 ms per keyword. The I/O scan time is just 0.225 milliseconds. It is ideal for medium to large control applications.

This controller uses a 3-chassis rack system. It supports up to 30 module slots. The backplane current load is 1 Amp at 5 Volts DC. It also draws 200 mA at 24 Volts DC. The processor has a 1-millisecond Selectable Timed Interrupt. It also features a 0.5-millisecond Discrete Input Interrupt. These features make it highly responsive for critical processes.

Application Scenarios

The 1747-L541 is perfect for HVAC control systems. It works well in SCADA applications. It is also common in material handling lines. The processor supports distributed I/O setups. You can use it with a communication adapter on the CPU rack. It also works with a scanner on remote I/O racks. The DH+ network supports multi-drop topology. The RS-232 port can connect to DF1 or DH-485 networks. You can also use it for Modbus RTU communication. This flexibility makes it suitable for many industrial environments.
