IMPORTANT NOTES:
1. Output signals should be used only to drive external relays. Do not power external
devices directly through output signals. Electrical noise will damage the output
signal relay.
2. If an inductive load (such as a relay) is connected to an output signal, be sure to
install a diode as shown to prevent damage to the output photocoupler:

Notes:
1. To close an input signal, short the circuit between the input pin (1
– 8) and a
GND(ground) pin (pins #11 - 13).
2. Input signals are powered by the robot
‟s internal power supply: 24 volts, maximum 2.5
mA
3. Check the status of an input signal using the SET I/O command (see
- Set I/O
). When the input pin (pin 1
– 8) is connected to a GND pin
(pin #11 - #13), the value of the input is 0.
