GU641B is a new generation Automatic Mains (Utility) Failure module for single Genset, which adopts
bran-new outline configuration, focus on the requirements of customers, and perfectly improves the
performance of controller. It fully meets the auto control requirements of different kinds of Genset for
user or special assembly factory.
The module also monitors and protects the engine, indicating operational status, fault conditions and
metering on the front panel LCD and LED.

| Measurement
|
| 2 analog inputs for kinds of optional built-in sensors, parameters also can be configured by user.
|
| More outputs of configurable auxiliary control relays.
|
| More configurable isolated digital inputs.
|
| Buttons on control panel are used for selecting control modes, starting and stopping the operating
procedure, displaying data and modifying the parameters. LED indicators are used for indicating
the operation mode of controller and the running status of Genset, and LCD displays each
measuring parameter and status.
|
| Flexible equipped with RS485, RS232 and USB, realizing remote monitor; or communicated with
PC, fully realizing functions of remote signaling, telemetering and remote control, can read and set
the running parameters of controller.
|
| All connections of the controller are by secure plug and socket, for ease and convenience to connect,
move, maintain and replace the device.
