Description
With the RS485 relay modules AD-KAB 40 GT and AD-KAB 80 GT, 4 or 8 potential-free NO contacts can be controlled from a distance via RS485 bus. The used Modbus-RTU protocol on these devices on the RS485 bus is an open standard and therefore extremely flexible. The up to eight relays can be individually controlled via a separate Modbus register. The devices are equipped with two rotary coding switches, which can be used to set the bus address on the device. If the DIP switch is active (in manual operation) bus commands for the respective relay are ignored because the manual operation has priority. Due to the compact and efficient switching power supply, the devices can be operated in a wide supply voltage range.
Application
Remote control of loads such as valves or motors in building automation as well as in automation technology.
Attention: A mixed wiring of the relays of extra low voltage and grid voltage is only permitted to a limited extent. For example, care must be taken that relays with 24 V and 230 V signals are not adjacent.
