The 1747-L531 has 30 module spaces in the local chassis and a maximum of 3 local chassis. The hardware components of the CPU include a memory module, keyswitch, and an Operating System download protection jumper which should not be moved unless updating the processor Operating System firmware. On the front panel, the 1747-L531 features a DH-485 Channel 1 port and a DH-485/DF1/ASCII Channel 0 port. There are also LED indicators to relate operational status information.
The 1747-L531 has standard battery-supported RAM and flash back-up memory. The 1747-L531 has an 8K words user memory: 4K words for data and program and 4K words for data only. The backplane current for the 1747-L531 at 5V is 500mA and at 24V is 175 mA. The CPU requires 1ms for program scan time and 0.225ms for I/O scan time. Additionally, the 1747-L531 has a maximum of 480 local analog I/O. With the 1747-L531, it is easy to incorporate a 1747-SN remote I/O scanner module. This will aid in configuring I/O on a universal remote I/O link. Another option is to add the 1747-SDN DeviceNet module to ease the configuration of I/O on a DeviceNet network. Between communication channels, the 1747-L531 has 500V DC isolation and 1500V AC isolation between the backplane and the I/O. In addition, the CPU has a dielectric withstand rating of 1500V AC and has the EN50082-2 and EN50081-2 industrial emission certification.
