The Allen-Bradley 1747-L541 is an SLC 5/04 processor, 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 has 16K, 32K or 64K words of memory and can control up to 4096 input and output points. In terms of communications, the 1747-L541 has a built-in DH+ channel that supports extended messaging capabilities and high-speed communications. It also has an RS-232 channel to support 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.

The typical program scan time for each keyword of 1747-L541 is 0.9 ms, and the typical I/O scan time is 0.225 ms. It requires A backplane current load of 5 A 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 13-M64 flash storage device with 1747 KB of memory. The SLC 5/04 includes a 3-digit key switch on the front panel for selecting Run, remote, or program modes. The 1747-L541 SLC 504 features RUN, FLT, BATT, FORCE, DH+, and RS-232 LED status indicators for troubleshooting and diagnosis. The SLC 500 series processors feature a simple, cost-effective design with proven installation experience in HVAC control, SCADA, and material handling applications.

The Allen-Bradley 1747-L541 is an SLC 5/04 controller with an integrated 16 KB of 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 ideal for use in mid-sized applications, as the controller is able to implement distributed IO applications 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 packet, detection enabled and parity parity (RS232 port) and 57.6 Kbaud, Data Highway Plus (DH+) node address = 1.

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

The controller has passed the UL certification, meets the U.S. and Canadian safety standards, meets the CE standard and carries a C-Tick mark.
