Since the I C address space consists of 3 bits that means that up to 8 unique devices can share the same I C communications bus On the I2C Relay8 the I C address is configured with three jumpers 1 for each bit of the address Figure 6 shows you where to find these jumpers To set the first bit of the address to 1 short the 1 and ADR pins of JP3 together To set the first bit to 0 short the 0 and ADR pins of JP3 together Repeat with JP4 and JP5 to set the second and third bits of the address Using the I2C Relay8 Once your I2C Relay8 is connected to your controller and the unit s address is configured how exactly you actually use the product will rely heavily on the controller interface If you are not using one of our controller units your controller must write 2 bytes of information onto the I2C bus each time you wish to change the state of 1 or more channels a byte for the address of the board you want to talk to and a byte that represents which relays should be engaged and which relays should be disengaged Manufacturer P N KA I2C 8 RELAY Page 7 15 Revision D September 2011 8 Channel Relay Output Board Via 2C Protocol P N KA I2C 8 RELAY Address Byte Bit7 Bit6 Bit5 Bit4 Bit3 Bit2 Bit1 BitO 0 1 1 1 X X X 0 A2 A1 AO R W JP5 JP4 JP3 Status Byte Bit7 Bit6 Bit5 Bit4 Bit3 Bit2 Bit1 BitO

8. nnection You can also have I2C Relay8 modules working side by side with 12C Opto8 input modules on the same controller Manufacturer P N KA I2C 8 RELAY Page 4 15 Revision D September 2011 8 Channel Relay Output Board Via 2C Protocol P N KA I2C 8 RELAY How to Use This Device Setting Up the Controller Perhaps your preference is for stand alone operation or remote accessibility or a setup which doesn t rely on an Ethernet connection Whichever controller you choose there are distinct advantages to each model While operation of your controller can be as simple as plugging your controller into your power source and then connecting the I2C Relay8 to your controller we strongly encourage you to refer to the setup directions in the documentation for your controller Powering Up the 12C Relay8 Once your controller is properly powered up and configured it s time to set up your I2C Relay8 First you have to decide how you are going to power the module through the external power or through the I C port It is recommended that if you are going to connect more than two modules to the controller you should bring power in through the terminal block TB17 Once you have decided how to power your I2C Relay8 there is a jumper JP7 that needs to be configured as illustrated in Figure 4 You need to make sure that it is in the correct position so that the appropriate power source is used otherwise the unit will not function
