  I-8x37-80, I-8x17
    I-8x37-80: Faster CPU (80 MHz) Ethernet ISaGRAF PAC
  I-8x17: 40 MHz ISaGRAF PAC
The I-8437-80/8837-80, I-8417/8817 is an ISaGRAF PAC and includes ISaGRAF SoftLogic, ISaGRAF is a Windows programming tools and also provides powerful debugging tools including On-line Motoring and Control and also Off-line Simulation. There are more than 300 function blocks built-in the PAC for various Industrial Applications including PID, motion, remote IO, serial communication, SMS, retain variable, scaling, etc.

In hardware, I-8xx7 has 3 or 4 serial ports, support Modbus RTU slave protocol and it can easily communicate with PC/HMI/OPC Server and Touch panel. The I-8xx7 also supports up to 2 COM ports of Modbus RTU / ASCII master protocol to integrate with other Modbus devices. The I-8x37-80 has one 10M Ethernet port.

The I-8xx7 supports various High/Low profile I/O modules. The user can choose Local I/O modules:I-8K/I-87K I/O modules and RS-485 Remote I/O modules:I-7000 or expansion units (I-87Kn or RU-87Pn) plugged with I-87K serial I/O modules.

SRAM Expansion
Battery Backup SRAM With a S256/S512 (plug in the socket of the back-plane), data can also be stored in the S256/S512. PC can load these data via COM1 (or COM2 of I-8417/8817, or Ethernet Port of I-8437-80/8837-80). PC can also download pre-defined data to the S256/S512.
Optional: S256: 256 KB, S512: 512 KB
*Note: COM5 ~ COM20 are resided at the expansion boards if they are plugged on slot 0 ~ 7 of I-8xx7-80.
