GAMX-D Control Board
Technical Parameter:
(1) AutomaticControl
1. Input signal: 4-20mA
2. Output signal: 4-20mA
3. Running direction: In standard form, the actuator (facing to output shaft) opens clockwise, the 4mA valve closes, and the 20mA valve opens.
4. Interrupt retention: Standard: the actuator remains in place when the signal is lost.
(2) Remote Control
1. Standard: The remote control is passive contact control. In the case of dry contact control, the actuator can receive pulse remote commands (without self-holding) to complete the opening and closing of the valve.
2. Non-standard: The remote control is passive contact control. In the case of dry contact control, the actuator can receive pulse remote commands (self-holding) to complete the opening and closing of the valve.
(3) Local Control
1. Standard: The control is passive contact control. In the case of dry contact control, the actuator can receive pulse local commands (without self-holding) to complete the valve opening and closing.
2. Non-standard: Through the dial switch, the actuator can receive the pulse local command (self-holding) to complete the opening and closing of the valve.
