PIO- This is the “workhorse” of the speedgate. The Primary I/O Board is located inside
every pedestal, except the last pedestal in the suite. There is one PIO per lane. This board
receives incoming power, all access control input signals, and inputs from the Remote
Lane Controller. This board outputs serial communications to the SIO, alarm conditions
via relays, and produces sound. The PIO contains the master program for how the lane
will function, as well as saves all of the settings for each lane.
Chopper Board & Resistor –
This board is in line with the direct motor power. It is
used to direct any generated power from the movement of the arms into the resistor to
prevent damaging any components on the PIO.
Motor & Gearbox – Each lane has a primary and secondary motor. The primary motor
is directly connected to the secondary motor, to the chopper assembly, and to the mini-
master.
B: Secondary Side Electronics
Transmitter Sensors- There are 17 transmitter sensors that provide a signal for the
receiver beams in the OBSG-HG-CV. The transmitter sensors will always be found on the
secondary side of the lane.
