I/O expansion modules

Unitronics has released a line of enhanced I/O expansion modules. Based on the same platform as the previous modules, these four compact devices offer up to 32 digital I/Os per unit, plus three additional analog inputs for maximum I/O capacity and minimised cabinet space.

Equipped with detachable plug-in I/O connectors, the XL-IO modules (IO-D16A3-TO16, IO-D16A3-RO16) can be expanded up to eight times with the use of Unitronics’ EX-A1 expansion adapter, and they can also be used together with regular Unitronics I/O modules.

The XL-EX modules (EX-D16A3-TO16, EX-D16A3-RO8) do not need an EX-A1 expansion adapter. The XL-EX modules incorporate EX-A1 adapter technology but add built-in I/O to serve as the first link to the PLC. Up to seven XL-IO or standard I/O modules may be connected to each XL-EX module.
