Toshiba V-Series S2E/S2T Small Powerful Modular Style Programmable Controller
Toshiba Updated: 2007-07-18Toshiba's S2E/S2T controllers are small, modular type programmable controllers suitable for simple relay replacement all the way to complex control applications. The S2E/S2T are 3rd generation T2 Series CPUs used with V-Series racks, I/O, and power supplies. The S2E/S2T provides a functional, economical, and compact solution to a wide range of applications in automotive, machine control, and process control systems.
Key Features
- T-Series Compatible. Any program written for a T-Series CPU can be downloaded directly into the S2E/S2T without modification.
- Comment Storage in CPU. Device/register tags and comments can be stored in CPU module. Tags and comments can be viewed in the on-line mode without access to the original program.
- Large Program Memory.
