Input Signal Name Input Device Type and Specifications
PWM Input
High-speed opto-isolator LED, forward voltage drops (Vf) 1.5 VDC
Off state Vmax +0.8 VDC
On state Vmin +3.5 VDC @ 3 mA on state (continuous) Vmax +6.7 VDC @ 10 mA Frequency, max. 100
kHz (p100) 200kHz (p150) Max PWM = 37.5%
Max Pulse Length = 600 microseconds
Remote Reset/Start Request Bi-directional opto-isolator LED, forward voltage drops (Vf) 1.15 VDC
Remote Interlock Off state Vmax < 1.0 VDC
Shutter Open Request
On state Vmin ±5.0 VDC @ 7 mA on state (continuous) Vmax ±24.0 VDC @ 40 mA
Important Note: The Remote Reset/Start Request input must not be sent until ’s +5 VDC power
supply has stabilized (approximately 200 ms after DC power-up).
Output Signals
P100/150’s five user outputs correspond to the status functions described below. These outputs are
opto-isolated solid-state relays that allow for high-side or low-side switching. The shared connection,
Output Common, is separate from the laser’s chassis ground to allow high-side or low-side switching and
to isolate control signals for optimum EMI performance.
