IMPORTANT ! please read the whole manual before
connecting the motors and external power supply.
First, connect the module to the bus board of your
modular. Power up the modular and then connect the
power supply for the motors. Connect some trigger
signals to the trigger inputs. Now the LEDs for every
output should be indicating that there is already
a motor driving signal present. Connect the solenoid
to its socket briefly to check whether it is working.
If not, disconnect the power supply for the motors
immediately! After a while of using the solenoids,
please check that they are not overheating. If they
are - turn down the output pulse width knob or check
if they are not specified for lower voltages.
The module has four channels: A, B, C and D. They
have identical driving circuitry. The power supply is
shared by all channels.
SOLENOID can drive four solenoid motors. Motor driving
circuitry and CV input circuitry are optically isolated
without any ground connection. This avoids any possible
noise or power transfer between the motors and the mo-
dular circuitry. Therefore it requires an external 12V-24V
DC power supply for driving the motors. The power
supply voltage should match the recommended power
supply voltage of the solenoids. We recommend to use 12V
solenoids.
1
The power input jack has a standard 2.1mm power
plug with center-positive polarity. I.e. “+” is in the middle,
surrounded by “-“. The voltage should be 7.5 - 12 V DC.
Please make sure that no part of the motor power supply
is touching the metallic front panels of another module.
This would connect the grounds and noise transfer could
be occur. The power supply for the motors provide give at
least 1A, but the final current consumption depends on
the type of motors used! We highly recommend to use
modified PC power supplies that are protected. Please see
www.bastl-instruments.com for more details.

The solenoid output connectors are standard power
plug with 2.1mm center pin. The polarity of most solenoids
doesn’t really matter. Once there is current flow they
trigger. Please connect each solenoid one by one to the
connector that is already being triggered and check if it
is moving. If not, disconnect it immediately and look for
mechanical or electrical connection problems.
3
The trigger input sockets react to standard 0-5V trigger
signals. On the rising edge of the pulse, the output pulse for
the solenoid is generated.
4
The output pulse width knob adjusts how long the
output pulse for the solenoid is. Depending on how long
you drive the solenoid, it can hit the object with more or
less power. The knob can be therefore used for adjusting
the dynamics. Most solenoids are limited by the amount
of time they can be turned ON so that they don’t overheat.
Usually it is less than 50% of ON time. The module takes
care of having the motors turned off for at least 50% of
the operating time. If the motors start to overheat, please
turn down the output pulse width knob.
