Connector Pin Assignments and Signal Levels
Channels 1–4 D-Subconnector Pins
NOTES:
• Each channel of the PICO controller has an associated 25-pin D-subconnector. The Y-connection cable (P/Ns
7028222 and 7012975) is normally used to connect the PICO controller/PICO
Toµch
controller to the PLC.
• The IN1 to IN10 and IN_STOP input signals are used to control the channel output signals (pulse-pause blocks).
These input signals can be generated by switches (hand or foot switch, limit switch, relay, light barrier, etc.) or by
electronic control devices (PLC or similar).
• A semi-conductor relay must be used to receive a clear, bounce-free signal.
• The terms input and output in the following table refer to the connections on the Y-connection cable (P/Ns
7028222 and 7012975).
Power Supply Socket Pins
CAN Interface D-Subconnector Pins
Through a CAN interface, the PICO controller can communicate with a primary device via the CAN bus. Without
communication, the unit operates autonomously.
