Enabling passage through tension pulse is shown in the image below. It is necessary
to observe the polarity of the V c voltages and to use an external resistor for high
d
voltages (110V and 220V).
The control board also has inputs for optical sensors (CN11) that monitor rotation
without mechanical wear, and two opto-isolated inputs to clear the

Outputs
Turnstile Tx1500
board has outputs for return signals, electromagnets, pictogram,
collecting box, and sound alarm.
Return signals
Return signals indicate the moment and direction of passage and are originated at the relay
–
normally open contact (NO) or normally closed contact (NC). Connect the outputs according
to the image below:
Electromagnets
Electromagnets are activated for blocking the turnstile. Opposite to the traditional
solenoids, electromagnets do not cause abrasion between the coil and the locking
device, avoiding malfunctions. Moreover, the activation is done through a transistor,
and not a relay, avoiding the electromagnet to be blown due to the
“
contact wielding
”
(there is no mechanical wear).
Sound alarm
The sound alarm output is activated by a NPN transistor (maximum 500 mA) every
time that
