Communication with the user system is possible by adding a circuit board with protocol selection and using a serial method fieldbus connection. All communications (commands and messages) between the actuator and the system are transmitted over the same dedicated cable. Currently, the following communication protocols are supported by products.
1. PROFIBUS bus type electric actuator
1)Without repeater 1200m, with repeater up to 10km
2)Up to 32 actuators per bus without repeater, 247 actuators per bus with repeater
3)Communication distance 1200m, scan time 700ms when 30 actuators are on line
4) Loop current 20 mA, 15 volts
5)ESD emergency shutdown function
2. MODBUS bus type electric actuator
1)Without repeater 1200m, with repeater up to 10km
2)Without repeater up to 32 actuators per bus, with repeater up to 247 actuators per bus
3)Communication distance 1200m, scan time 700ms when 30 actuators are on line
4) Loop current 20 mA, 15 volts
5)ESD emergency shutdown function
6)Transmission mode: RTU baud rate: 1.2K-115K
3.HART bus type electric actuator
1)Support HART protocol version 6.0 and 7.0
2)Communication frequency: 1200bits/sec
3)Support point-to-point communication or multi-point communication
