Features
Relay board can communicate and send data to any device via open protocol Modbus RS-485 examples are PLC’s EDGE devices Industrial, PCs, HMI, Routers/firewalls and much more.
Board uses a unique design of solderless relays were in case of failure of one relay you don’t have to replace the whole board but you can use plugin relay for each channel. All outputs is isolated relay outputs Board has 6 board support that makes it easy to mount virtually in any position. With an additional layer of protection for the board, reliability, board has a clear protective coating to keep moisture and dust away from the board in a harsh environment.
Output terminal block connection is made through Extra heavy-duty 40A terminal block that there is no need for extra equipment to double your heavy wires so you can connect all to the same terminal block. Tag is a Boolean, Modbus function code is 15: Force multiple coils
Dip switches making easy to change Modbus addressing up to 32 address via 1st five dip switches last 3 dip switches used for baud rate
Switch 1………LSB of Modbus Address
Switch 2………Bit 1 of Modbus Address
Switch 3………Bit 2 of Modbus Address
Switch 4………Bit 3 of Modbus Address
Switch 5………MSB of Modbus Address
Switch 6………Not Used - Must be in ON Position!
Switch 7………BAUD Rate Select 0
Switch 8………BAUD Rate Select 1
Switch 7 OFF, Switch 8 OFF………. 9600 BAUD
Switch 7 OFF, Switch 8 ON………19200 BAUD
Switch 7 ON, Switch 8 OFF……… 38400 BAUD
Switch 7 ON, Switch 8 ON…….. 115200 BAUD
The Modbus Address and BAUD Rate settings are read whenever the board powers up. The values are stored in internal memory. Changing the Modbus Address and/or BAUD Rate is accomplished by modifying the switch settings then cycling power to the Switch Board. The Switch BoardMUST be restarted in order for the new settings to take effect.
The 10 Pin Switch Board Interface Connector is designed to interface directly to the A&H Bernik RelayBoard MODEL:.AJSWB24VMOD A “Keyed” 1 to 1, 10 Pin Ribbon Cable is connected between this interface connector on the Switch Board and the interface connector on the RelayBoard. The interface allows the A&H Switch Board to monitor, override, bypass and otherwise place the RelayBoard into automatic mode. When connected, the A&H Switch Board and Relay Board interact with each other as described above.
If more that one board connected 6 pin header been added so you can connect daisy-chain with a ribbon cable in a matter of seconds (sold separately)
All you need is to wire 1st Board with 5 positions removable terminal block. Board has clear marking for power and RS-485 wiring.
