General Description

The DM6952HR dataModule® combines, on one board, 16 power relay outputs. These relays may be used to reliably switch voltages from 5V DC to mains voltages of 220VAC. The onboard relays have two identical pairs of contacts. These contacts are connected in parallel. Both Normally Open (NO) and Normally Closed (NC) contacts are available on the I/O connectors. Use this board in applications such as AC or DC power circuit breaking, motor and actuator control or voltage level shifting.

PC/104 Base Address Settings

Each PC/104 board in the stack requires a unique address setting for proper communication. The DM6952-HR uses physical jumpers to set the address. The jumper block is located just above the PC/104 connector on the top side of the board. Address 300h is the default address (shown in blue).
