Application Circuit
Modulation
E - Modulating with a control unit
- Input: 4~20mA / 0~10V
- Output: 4~20mA / 0~10V
Connecting Details:
- Connecting AC85-220V supply power line to L and neutral to N.
- Connecting 4-20mA/2-10V input signal source from control system to input-/+.
- Connecting Output -/+ to the system to send out the real-time valve position.
On - Off
A - With 2 active end-position signal outputs
- Control actuator to open or close with K
- The output terminal of end-position OPEN/CLOSE will send out the event as a 220VAC active signal form when the end-position was reached.
Connecting Details:
- Connecting AC85-220V supply power neutral to P1.
- Switch AC85-220V line to CLOSE(P2) to close the valve
- Switch AC85-220V line to OPEN(P3) to open the valve.
- P5 is end-position OPEN terminal which will output a AC220V source which can be used to drive an Indication light when actuator reached end-position of open.
- P6 is end-position OPEN terminal which will output a AC220V source which can be used to drive an Indication light when actuator reached end-position of close.
- Connect earth to P7.
B - With 2 passive end-position switche
- Control actuator to open or close with K
- The output terminal of end-position OPEN/CLOSE will send out the event as a passive signal form when the end-position was reached.
Connecting Details:
- Connecting AC85-220V supply power neutral to P1.
- Switch AC85-220V line to CLOSE(P2) to close the valve
- Switch AC85-220V line to OPEN(P3) to open the valve.
- P4 is the COM for passive contact signal of end-position OPEN/CLOSE which is normally connected to signal GND.
- P5 is end-position OPEN terminal which will be connected to COM when actuator reached end-position of open.
- P6 is end-position CLOSE terminal which will be connected to COM when actuator reached end-position of close.
- Connect earth to P7.
G - DC motor with 2 end-position switches
- Control actuator to open or close by the supply power direction between the terminal 1 and 2
- The output terminal of end-position OPEN/CLOSE will send out the event as a passive signal form when the end-position was reached.
Connecting Details:
- Connecting DC24V+ to P1 and DC24V- to P2 to close the valve.
- Connecting DC24V+ to P2 and DC24V- to P1 to close the valve.
- P3 is the COM for passive contact signal of end-position OPEN/CLOSE which is normally connected to signal GND.
- P4 is end-position OPEN terminal which will be connected to COM when actuator reached end-position of open.
- P5 is end-position CLOSE terminal which will be connected to COM when actuator reached end-position of close.
- Connect earth to P7.
