CONTROL Fig 4 2 This diagram illustrates the output relay connection Resets On circuitry only enables one reset that clears the outputs This is the first reser occurring at power up The state of the relay outputs does not change even though a system software or hardware reset WDT may occur Only a software write to the output register will update state of the relay outputs DM6858 DM5858 user s manual 18 RTD Embedded Technologies Inc User s Manual Fuses The DM5952 DM6952 Power relay board is protected against over loading or error conditions in the relay coils with two fuses These fuses protect a group of 8 relays The fuses are located to the top of your board away from the bus connector The fuse type is 2A quick blow DM6858 DM5858 user s manual 19 RTD Embedded Technologies Inc User s Manual Chapter 5 BOARD OPERATION AND PROGRAMMING This chapter shows you how to program and use your DM5952 DM6952 It provides a complete description of the I O map plus a detailed discussion of programming operations to aid you in programming Defining the I O Map The I O map of the DM5952 DM6952 is shown in Table 5 1 below As shown the module occupies two addresses The Base Address designated as BA can be set using the jumpers as described in Chapter 2 Board settings The following sections describe the register contents of each address used in the I O map Table 5 1 DM5952 DM6952 I O Map Register
