MitsubishiQ02CPUPLC CPU Module — MELSEC-Q, 28K steps, 4096 I/O points, RS-232

Product Description

What this part isThe Mitsubishi Electric Q02CPU is a CPU module for the MELSEC-Q Series programmable controller. It controls 4096 I/O points (8192 I/O device points), holds 28K steps of program, executes an LD instruction in 79 ns and has an RS-232 port and a memory card interface. It mounts on a MELSEC-Q base unit and draws 5 V DC from the Q-series power supply module.
