1747-L541/B | Controller module

The 1747-L541 is a controller module for the SLC 500 Modular Hardware by . It comes with Memory or 16 KB, and built-in communication interfaces such as 9-Pin RS-232 and Data Highway Plus (DH+). It is capable of 4096 Inputs points and 4096 Outputs points with an Analog I/O count of 480, 16K words of user memory, and an I/O scan time of 0.225 milliseconds.The 1747-L541 has a typical Program Scan Time per Keyword of 0.9 milliseconds and a typical I/O scan time of 0.225 milliseconds. It requires a backplane current load of 1 Amp at 5 Volts DC and of 200 mA at 24 Volts DC. It has a 1-millisecond Selectable Timed Interrupt (STI) and 0.5 milliseconds Discrete Input Interrupt (DII). For program and data table storage, it uses a 1747-M13 flash-based memory device with a 64 KB memory. The SLC 5/04 includes a 3-position key switch on the front panel for selecting the Run, Remote, or Program modes. The 1747-L541 SLC 504 has RUN, FLT, BATT, FORCE, DH+, and RS-232 LED status indicators for troubleshooting and diagnostics. The SLC 500 series of processors has a simple, cost-effective design with a history of good installations in applications such as HVAC control, SCADA, and material handling.
