TESCO’s L3000® I/O configurations are customizable to meet your needs now and in the future.

Mixed I/O Modules
TESCO Mixed I/O modules have one of each type of I/O. These cards are efficient for smaller applications, since only one I/O card is required, rather than one of each type. These cards also allow the use of the compact L3000e packaging on a PLC with all types of I/O.

High Density Dedicated I/O Modules
TESCO Dedicated I/O modules allow the greatest flexibility for systems with higher I/O demands. They are the perfect solution for systems with a high demand I/O. Dedicated I/O modules may be combined with mixed I/O modules for the utmost flexibility on systems with medium to extremely large I/O demands.
