MOSFET Digital Output
The MOSFET digital outputs are designed to control electro-hydraulic valves but can also be used
to load other accessories such as lamps or motors.
Digital inputs
Estop
The digital inputs can be used as a switch to control different functions on the central
unit or on the HCU. The maximum input voltage shall not exceed the supply voltage.
The Estop function works as a safety function.
The output is active each time the HCU is active and communication has been established with
the Central unit. This output is normally connected to a dump valve. It is required for the system
installer to use this or similar function for the operator safety.
The Estop digital output shares the same properties as the other digital outputs.
Exspansion boards
Description of expansion functions Number of exspansion function
Analof inputs 1-10
Analog outputs 1-5
Digital I/O 1-20
PWM 1-5
The main board may be used stand alone or together with one expansion board.
There are several different expansion boards.
All expansions boards have the same mechanical outline.
They may have different funcionalities depending on customers application.
The differnt functions are exemplied in the table below:
