Need help selecting a PLC family? Use our selection tool to configure and order.
Stackable PLCs do not use base chassis; instead, the backplane (data bus) is constructed through connections made when the modules are stacked together. Terminal bases allow easy I/O hardware changes after the system is configured and stacked. Do-more T1H terminal bases are available in screw or spring clamp versions for both half-size and full-size I/O models.
