SAMPLE INPUT CIRCUIT

Sample input circuit
DB-9 I/O Connections
The figure below illustrates one method of applying the Laser Enable signal using a customer-supplied
limit switch or relay contact powered by the OEM vi30/40's DC Out output (+5 V, 250 mA).
DB-9 I/O PINS
The following figure shows another variation for applying a Laser Enable signal. In this case, the
customer is also supplying the voltage necessary to drive the vi30/40's enable circuit.
DB-9 I/O PINS
The Laser Enable input is a direct 5V logic input. Do not send a voltage signal to the Laser Enable
input (Pin 9) until DC power is applied; otherwise, the control board will be damaged.
Observe all 5V logic specifications and precautions when integrating OEM vi30/40 inputs and
outputs into your control system.
