Sure Grip DFA2 Driver Boards directly control proportional valves, such as the Sauer Danfoss PVG 120 & PVG 32 valves.
SURE GRIP DFA2 DANFOSS ADAPTER DRIVER
The Sure Grip DFA2 Driver is a next generation Danfoss driver board that expands upon the original DFA design with the addition of a Caterpillar ECM compatible version
(DFA2-C1, DFA2-C2). The Sure Grip DFA2-01/02 provides direct from handle to valve proportional control™ for the operation of industry-standard ratio metric proportional valves.
You can use Sure Grip Controls' non-contact proportional modules or the Sure Grip JSL/JSM Series joysticks to directly control proportional valves such as the Sauer Danfoss™ PVG 120 and PVG 32 series proportional valves. While the Sure Grip DFA2-C1/C2 is designed to interface to Caterpillar ECM's that require PWM control input signals.
The Sure Grip Danfoss Adapter Driver is installed as an in-line module on a Sure Grip Control's handle or joystick wiring harness. The operator will have bi-directional proportional control of Danfoss™ proportional valves using a proportional slider module, two proportional flex pushbuttons or a JSL/JSM Series joystick. (The DFA2-01/C1 version is configured for use
with our PC-V2 modules, whereas the DFA2-02/C2 version is for use with the JSL/JSM Series joysticks.)
While the Sure Grip DFA2-01/02 Driver provides the drive signal required by the valve, and includes a high current valve enable signal whenever the drive signal is off neutral. The DFA2-01/02 also includes factory programmed ramping of 300ms to help reduce pressure spikes in the hydraulic system.
The heart of the Sure Grip DFA2 is a microcontroller which constantly monitors the machine's operating voltage, generates the proportional valve drive signals and reads the input devices. Built-in software safety features will cause a safe shut-down of the valve should there be a failure in the proportional input devices, or in the wiring between the handle and
the module, or if there is a computer malfunction. The hardware is designed to withstand potentially damaging electrical surges (common on mobile hydraulic machinery) and to survive wiring faults and installation errors.
