The Allen-Bradley 1747-L541 is an SLC 5/04 processor that is part of the SLC 500 family, which also includes the 1747-L541, L542, and L543 controllers. It is a high-performance processor with faster communication speeds and shorter program execution times. The SLC 5/04 is equipped with 16K, 32K or 64K word memory and can control up to 4096 input and output points. For communication, the 1747-L541 has a built-in DH+ channel that supports extended messaging capabilities and high-speed communication. It also has an RS-232 channel for supporting DF1 radio modem, DH-485, ASCII and Modbus RTU communications. For programming, it includes advanced mathematical instructions and various additional instructions. It also supports remote I/O, DeviceNet pass-through, and indirect addressing.

1747-L541 The typical program scan time for each keyword is 0.9 ms and the typical I/O scan time is 0.225 ms. It requires a backplane current load of 5 amps at 1 V DC and 24 mA at 200 V DC. It has a 1 ms selectable time interrupt (STI) and 0.5 ms discrete input interrupt (DII). For program and data table storage, it uses a memory device based on 1747-M13 flash memory, with 64 KB of memory. The SLC 5/04 includes a 3-digit key switch on the front panel for selecting run, remote, or programming modes. The 1747-L541 SLC 504 features run, fly, hit, force, DH+, and RS-232 LED status indicators for troubleshooting and diagnosis. The SLC 500 series processors feature a simple, cost-effective design with a proven installation history in applications such as HVAC control, SCADA, and material handling.

The Allen-Bradley 1747-L541 is an SLC 5/04 controller with an integrated 16 KB user memory designed to handle up to 4096 inputs and outputs. The controller is a modular SLC 500 programmable logic controller (PLC).

The 1747-L541 is well suited for use in mid-sized applications, as the controller is able to enable distributed IO applications by using a communication adapter on the CPU rack and a communication scanner on the IO rack. The RS232 communication port can be configured for DF1 and DH485 point-to-point topologies, while DH+ communication supports long-distance and multipoint topologies.

Alternatively, the RS232 communication port can also be used with the 1761-NET-AIC to allow a serial port to connect to a multipoint network. The default Settings for communication ports are No handshake, 19.2 Kbaud, CRC error check, Duplicate packets, RS232 port detection and no parity, and 57.6 Kbaud, Data Superhighway Enhanced (DH+) node address = 1.

The 1747-L541 controller requires an SLC 500 rack to mount and connect to the electronic backplane. System power is also required to power the processor's internal circuitry through an electronic backplane.

The controller meets the UL certification of the US and Canadian safety standards, meets the CE standard and carries the C-Tick mark.
