ISA-389G universal auxiliary device
The ISA-389G universal auxiliary device can complete functions such as three-phase operation, voltage paralleling, voltage switching, etc., and can also insert a reset plug-in to complete the signal or contact reset function. The device can choose the following eight general function plug-ins according to functional requirements.
Cooperate with various protections to complete functions such as tripping and closing operations, voltage switching, voltage paralleling, and re-starting. The plug-in functions are mutually independent and do not affect each other. The device is larger and can be configured with 5 plug-ins. The installation sequence of the plug-ins is not required, and the use is flexible and convenient.
Features:
· The device is a standard 4U (full-layer) chassis, the structure is modular, and the backplane outlet adopts plug-in connection. The device has the characteristics of high reliability, flexible and convenient use.
· Three-phase operation plug-in with pressure blocking circuit, three sets of position signal output, and control return disconnection and accident audio output, with anti-jumping circuit and can be cancelled at the external terminal short circuit.
· Voltage parallel circuit has 10 voltage parallel function.
· The voltage switching circuit has 8 voltage switching functions. If more than 8 voltages need to be switched, it can be realized by using multiple voltage switching plug-ins.
· The device adopts imported fully-sealed, high-impedance, low-power relay, which greatly reduces the power consumption and heat generation of the device.
· Capable of adapting to various tripping and closing holding currents.
