Series B5950 Block Micro Proportional Driver

The Block Micro Proportional Driver is a compact electronic circuit built into an epoxy potted enclosure designed to control linear proportional solenoid operators. Features include selectable control signal inputs from 0 - 5 V or 0 - 20 mA with adjustable minimum/maximum current output. The output steps to the minimum current setting when 0.1 volts or 0.4 mA is applied to the control signal input. Also included in the compact package is a 0.1 - 20 second adjustable ramp-up and ramp-down output and sine wave dithering (PWM) with adjustable amplitude and frequency. The B5950 has an output current that is proportional to the command signal input.
 
Assembly and mounting of the unit is accomplished by use of a 6mm diameter mounting hole in the body of the unit. Connection is made by use of a miniature header strip which accommodates stranded or solid wire to 3mm diameter. Adjustments are made by turning screwdriver adjustment screws on the top surface of the unit. Additional features include on-board diagnostics such as a red indicator light for power and a yellow indicator light for output to the solenoid. The B5950 can be used to control any solenoid operator designed to meet the technical specifications as shown on this brochure.

Function
Minimum Current & Maximum Current
These two adjustments will vary the minimum and maximum output current limits. The minimum current can be set between 0 - 500 mA or 0 - 3 A, depending on output current option. The maximum current can be set in the range between the minimum current setting and the minimum current setting plus 1 A or 2 A, depending on output current option. The minimum current must be set first as described below.
 
Minimum Current Adjustment
Set both minimum and maximum current adjusters maximum counterclockwise. Apply the minimum input command signal (approximately 0.5 volts or 1.0 mA). Adjust the minimum current adjuster for a minimum current or to a desired system response. Back up adjuster until system stops responding. Proceed to maximum current adjuster.
 
Maximum Current Adjustment
Increase the input command signal to maximum. Adjust maximum current adjuster for a maximum current limit or to a desired system response.
 
Note: To minimize any effect of supply voltage, load resistance or temperature variation, make setup adjustments when these parameters are at the midpoint of the expected operating range for a particular installation. For example, if the expected operating temperature range is 20° C to 60° C, make final setup adjustments when system is approximately 40° C. If the supply voltage has a tolerance of 22 to 32 volts, make adjustments when the supply voltage is approximately 27 VDC.
 
Ramp Up/Ramp Down
Adjust to desired ramp up/ramp down time (0.10 - 20 sec.). Ramp time is linear and is proportional to the step change in the control signal. For example: 0.1 - 5 VDC change in control signal gives maximum ramp of 20 sec. 0.1 - 2.5 VDC change in control signal gives maximum ramp of 10 sec.
 
PWM Frequency
The output is pulse-width modulated to control output current within the minimum and maximum current settings. The frequency of the modulation is fixed at 1.2 KHz.
 
Dither
The coil current is sine wave modulated with adjustable frequency (30 - 150 Hz) and amplitude (0 - .5A peak to peak).
 
Reference Voltage
A regulated 5.0 VDC voltage is available for on site command voltage. Use of a 10K - 100K potentiometer connected from 5.0 VDC Reference to Supply Voltage (-) is recommended.
 
Output
The output is current regulated and will remain constant (within the limits specified under Technical Data on previous table) at the level set by the input command signal. Variations in supply voltage and load resistance have little effect.
