AutomationDirect BX-DM1-10ED1-D

The BX-DM1-10ED1-D is a BRX Do-more stackable micro brick programmable logic controller from AutomationDirect. It runs ladder logic programmed with Do-more Designer software and provides six discrete inputs rated 12-24 VAC/VDC plus four sinking discrete outputs at 12-24 VDC, along with one RS-232/RS-485 serial port. It has a microSD card slot, battery-backed retentive memory and accepts up to eight expansion modules.
