ELECTRONICS DANFOSS ADAPTER DRIVER BOARD

The DFA2 is the next generation driver board that expands upon the original DFA design with the addition of a Caterpillar ECM compatible version (DFA2-C1, DFA2-C2). The 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 JL/JM Series joysticks to directly control proportional valves such as the Sauer Danfoss™ PVG 120 and PVG 32 series proportional valves. The DFA2-C1/C2 is designed to interface to Caterpillar ECM's that require PWM control input signals.

The DFA2 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 JL/JM 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 JL/JM Series joysticks.) The DFA2-01/02 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 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.

DFA2 Board Features:
+ Convert signal from two PC-V2 modules, Proportional Slider Modules, or our JM/JL Series joysticks
+ Sauer-Danfoss PVG Valve compatibility (DFA2-01/04 configurations)
+ Caterpillar ECM compatibility (DFA2-C1/C2/C3 configurations)
+ Installed in-line with the handle wire harness, no extra wiring
+ Electrical protection built in
+ Self calibration for center voltage
+ High Current Switched enable output when off neutral
+ On-board 5 VDC power supply for control inputs (Joysticks, PC-V2 modules)
+ Operates on 12 or 24 VDC machines

DFA2 Configurations:
+ DFA2-01: Sauer-Danfoss PVG/PVE Series Proportional Valve Driver (PC-V2 module controlled)
+ DFA2-02: Sauer-Danfoss PVG/PVE Series Proportional Valve Driver (Joystick controlled)
+ DFA2-04: Sauer-Danfoss PVG/PVE Series Proportional Valve Driver with Float Mode (Joystick controlled, single axis)
+ DFA2-C1: Caterpillar ECM Compatible PWM Driver Board (PC-V2 module controlled)
+ DFA2-C2: Caterpillar ECM Compatible PWM Driver Board (Joystick controlled)
+ DFA2-C3: Caterpillar ECM Compatible PWM Driver Board with Adjustable Output Range (Joystick controlled)
