About 1747-L524:

The AB 1747-L524 is an SLC 500 processor. Also referred to as an SLC 5/02 controller, this processor has a maximum memory of 4000 modules for instructions and a maximum of 4096 modules each for discrete input and output. You can use more than 60 types of modules, such as analog, digital, and scanner modules, for this processor. However, this processor is not compatible with the 1746-BLM and 1746-MPM modules. Installing scanner modules to this processor will allow you to add DeviceNet, ControlNet, and Universal Remote I/O to the system, as well as add 19 additional instructions. This processor also has a maximum of 480 local Analog I/O and a maximum local chassis/slot of 3/30. Note that no additional data storage can be installed with this processor. However, you can use optional EEPROM modules. These memory modules allow you to save the contents of the processor RAM and load the data saved in the EEPROM memory to the processor RAM. The DH-485 communication port available with this processor is set to receive and initiate instructions but it requires the 1747-PIC if you will connect the port for programming.

Status indicators are available for this processor. The 1747-L524 processor can have 71 programming instructions and it can be configured using the RSLogix 500, PLC-500 A.I. Series, HHT, and APS programming software. It also has a user-replaceable battery that is estimated to last for an average of 2 years. This processor, measuring 145 x 35 x 142 millimeters, can be mounted using a chassis and it has an open-style enclosure. It has a maximum current of 0.9 A at 5 Volts DC and minimum Watts and total Watts of both 1.75 each. The program scan time of the processor is 4.8 milliseconds/K and the I/O scan time is 1.6 milliseconds. Bit execution is 2.4 µs. This processor also has a backplane current load of 350 mA at 5 Volts DC and 105 mA at 24 Volts DC. Depending on the power supply loading, its program scan hold-up time after the loss of power is from 20 milliseconds to 3 seconds. The operating temperature of this processor ranges from 0 to 60 degrees Celsius and the storage temperature is from -40 to 85 degrees Celsius. Its vibration is a 0.015-inch displacement peak-to-peak at 5 to 57 Hertz and 2.5 G acceleration at 57 to 2000 Hertz. It also has an operating shock of 30 G and comes with a non-condensing relative humidity of 5 to 95%.
