Functional FAQ

What is the difference between the DSQC 651 and DSQC 652?

While both utilize DeviceNet, the DSQC 651 typically offers 8 digital inputs and 8 digital outputs. The DSQC 652 (3HAC025917-001) doubles that capacity to 16 digital inputs and 16 digital outputs, making it the preferred choice for I/O-intensive robotic cells.

Does this module require a separate power supply for the I/O signals?

Yes. To maintain electrical isolation and protect the internal logic, an external 24V DC supply is required to power the field-side inputs and outputs. This prevents electrical noise from external actuators from affecting the IRC5 controller logic.
