Toshiba EX204-MARD8 Programmable Logic Controller Expansion Module

The Toshiba EX204-MARD8 is a 20-point digital I/O expansion module for the Toshiba EX20 Series PLC systems, delivering 12 digital inputs and 8 relay outputs to extend a controller’s I/O capacity. It mounts as a PLC Expansion Unit and connects directly to a compatible EX20 PLC CPU to support industrial machine automation across packaging lines, conveyor systems, assembly equipment, process control panels, and OEM machinery requiring additional discrete I/O. Specifically, the module provides 12 digital inputs and 8 relay outputs (20 points total), is an I/O expansion device for the EX20 I/O configuration, and supports ladder logic programming via the EX20 PLC CPU. Note: the listed unit has a broken holder/bottom mounting clip, and common replacements for this module include EX204-MATR8, EX20-MCRA3, and EX40-H1MARB5.
