Dual Solenoid Multifunction Valve Driver
With Joystick, Potentiometer and Control System Interface

The Dual Solenoid Multifunction Valve Driver provides accurate control of hydraulic proportional and directional valves used in mobile equipment and industrial processes, with input from a joystick, potentiometer or control system interface. This multifunctional design will support inputs from a joystick potentiometer with or without center tap, a standard potentiometer or commonly available control signals such as 0 to 5 Volts, 0 to +/-5 Volts, 0 to 10 Volts, 0 to +/-10 Volts, 0 to 20 mA, and 0 to +/-20 mA. The power supply connection is conditioned to withstand the harsh environment found in vehicular power systems. Maximum current output is adjustable from 0 to 2 Amps (300 mA and 100 mA output versions are available). A high low range input provides reduced output for limited operation. The driver is potted and packaged driver in a metal base.

Features:
  • High efficiency PWM with superimposed dither
  • Glitch-free high-speed power up permits the entire electronics package to be powered from safety interlock trigger switches or joystick mounted micro switches, when safety is of primary concern
  • High low range input provides reduced output for limited operation (i.e. training or operation in tight spaces)
  • Pump enable output is active only when the joystick is active
  • Fully sealed option for use in harsh environments (IP65 protection rating)
  • Electronic overload protection
  • Static and surge protection built in
  • EMI/RFI resistant
  • Adjustable deadband jumps
  • Adjustable minimum current (0 to 2 Amps) and maximum current (0 to 2 Amps)
  • Other current outputs are available
  • Adjustable asymmetrical ramps (0.01 to 5 Seconds) with symmetrical ramps user selectable
  • Center null to accommodate joystick or potentiometer centering errors
  • Master/slave option permits only one axis to operate at a time

Hydraulic Valve Controls
Technical Specifications: Dual Solenoid Multifunction Valve Driver
Order Codes:

P/N: DSDA-SMB-TB-01 (standard input, 0 to 2 Amp max. output, tabs)
P/N: DSDA-SMB-SC-01 (standard input, 0 to 2 Amp max. output, screw terminals)
P/N: DSDA-SMB-TB-01-300MA (standard input, 0 to 300 mA max. output, tabs)
P/N: DSDA-SMB-TB-01-100MA (standard input, 0 to 100 mA max. output, tabs)
P/N: DSDA-SMB-1K-TB 1K (pot input, 0 to 2 Amps max. output, tabs)
Operating voltage (power supply requirement):

9 to 32 VDC power supply range
Reverse polarity protection
Total current draw will be the sum of the currents drawn by all connected equipment plus 25 mA.

Control input signal options - voltage:

0 to 5 Volts (2.5V=0, +/-2.5V),
0 to 10 Volts (5V=0, +/-5V),
0 to +/-5 Volts (0V=0, +/-5V),
or 0 to +/-10 Volts (0V=0, +/-10V)
(user selectable by DIP switch SW1)
Other signal inputs are available. Contact manufacturer.

Control input signal options - current:

0 to 20 mA (10mA=0, +/-10mA),
or 0 to +/-20 mA (0mA=0, +/-20mA)
(user selectable by DIP switch SW2)
Other signal inputs are available. Contact manufacturer.

Potentiometer input:

The potentiometer connection provides a 5.0 VDC bias voltage as well as a 2.5 VDC center-tap driving voltage. A remote joystick potentiometer with or without center tap may be used. A 10K potentiometer is recommended. The unit accepts pots from 5K to 50K Ohms. A 1K pot input version is available.

Low range input (Imax/2):

This input, when active, will provide a 50% reduction in output current slope. It is used to increase the resolution of operation for limited operation such as when training new operators or during operation in tight quarters. It is activated by applying power (+ 9-32 VDC) to the Imax/2 tab and if not used, it may be left unconnected.

Input resistance:

Voltage mode: 500 K Ohms
Current mode: 250 Ohms

Range of maximum output current:

 2000 mA, 300 mA or 100 mA (see part numbers)
Maximum output current is limited to 2.5A (min. current setting + max. current setting <2.5A).

Solenoid resistance selection (nominal):

Rcoil < (Vpower supply - 1.5 V)/I-max

Minimum current setting (Solenoid A and B):

0 to 2.0A (adjustable) in 2A output version
0 to 300 mA (adjustable) in 300 mA output version

Maximum current setting (Solenoid A and B):

0 to 2.0A (adjustable) in 2A output version
0 to 300 mA (adjustable) in 300 mA output version
The maximum current is offset by the minimum current setting.

Current ramp time - up and down (Solenoid A and B):

0.01 - 5 seconds
(symmetrical/non-symmetrical user selectable by DIP switch 2)

Dither amplitude
Dither waveform
Current dither frequency:

0 to 10% of maximum current (adjustable)
Triangular
70 to 350 Hz ±10% of full scale (adjustable)

Protection class:

Potted
IP65 rating

Electrical connection:
- Potted Driver

Connection style - 22 flat tabs or screw terminals (complete with mating vertical plug-in terminals)
Tab connection version mates with 0.25 inch female tab connector, supplied by customer (Keystone P/N: 4470) and accepts 16-20 AWG wire
(Other connection styles are available to meet OEM requirements.)
