AutomationDirect (Cumming, GA) has released the latest addition to its PLC offerings, the Do-more T1H Series PLC. Using the proven Terminator field I/O hardware as a platform, the Do-moreT1H PLC supports stackable base units, discrete and analog I/O modules. The T1H CPUs high processor speeds not only decrease program execution time, but also allow the CPUs to support Ethernet connectivity and custom communication protocols as built-in functions. A Do- more T1H CPU supports up to 256 I/O points in three stackable rows. The I/O Configuration window performs full auto-discovery of all I/O modules in the local drop, simplifying system configuration. For larger applications, Ethernet-based remote I/O can be connected for hundreds of additional points.
