900719_FOCE : FOCE Relay Board This page last changed on May 29, 2008 by ckecy. # 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. # Links Spec Sheet Manual RTD Home Page # Specifications #### Host Interface Jumper selectable base address, I/O mapped #### Relay Outputs Number of lines 16 relays Breakdown voltage 1000 V Rms Max switching power (resistive load) 60 W (motor load) 30 W Max switching voltage 230 V DC Max switching current 2 A Nominal switching capacity 2 A, 30 V DC Contact resistance 100 mOhms max #### Connectors Outputs 50 pin header or screw terminals Bus connector PC/104 XT or AT-bus #### Power requirements Supply voltage +5V +/- 8% Supply current TBD #### Operating temperature range Standard -40 to +85 C # 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).
