System Integration:
-
This output module belongs to the Mitsubishi Electric MELSEC‑Q series.
-
Installs into any MELSEC‑Q series main base unit (Q3□B, Q5□B, Q6□B series) or extension base unit slot via the Q series backplane bus.
-
Compatible with Q series CPU modules (Q00J, Q00, Q01, Qn, QnH, QnPH, QnPRH, QnU series).
-
Output points are automatically mapped to Y device addresses based on slot position.
-
Fuse blow detection signal is sent to CPU; program can be written to monitor module status.
-
For detailed installation, wiring and configuration, refer to the MELSEC‑Q series User's Manual (Hardware Design, Maintenance and Inspection).
