Figure 3-13 Customer powered Laser Enable circuit
Figure below shows an isolated PLC output module switching the Laser Enable signal from a +5 V
source.
Figure 3-14 PLC switched Laser Enable circuit
RJ45 output circuitry
The Interface B (RJ45) connector has three user outputs that communicate laser status to the user’s
control system. As described in Table 3-6, the three outputs, Laser OK, Temperature OK, and Voltage
OK are ESD protected, but are not optoisolated. The Laser OK output is high (+5V) when lasing is
possible, otherwise the output goes low (0V) when a fault is detected. Temperature OK is high when
laser temperature is within limits; otherwise, the output goes low if laser temperature rises above thermal
limits. Voltage OK is high when the DC supply voltage is within limits; otherwise, the output goes low if
an under/over voltage condition is sensed.
OEM v30 outputs are voltage sources. Each output can source only 20 mA typical, 40 mA maximum, to
a ground referenced load (the ground reference, GND, is Pin 8). The control board will be damaged if
this current limit is exceeded.
The Interface B (RJ45) connector also includes a +15 VDC output voltage source, DC Out, that provides
a maximum current of 250 mA.
Table below provides RJ45 output circuit specifications while the following figure illustrates the output
circuit’s equivalent internal schematic.
Caution: Possible Equipment Damage
The Interface B (RJ45) Laser Enable input is a direct 5V logic input. Do not send a voltage signal to
the Laser Enable input (Pin 7) until DC power is applied; otherwise, the control board will be
damaged. Observe all 5V logic specifications and precautions when integrating OEM v30 inputs and
outputs into your control system.
PWM Negative (Pin 6) must be connected to GND (Pin 8) or it must serve as the return path for the
PWM Positive signal
