What is the Mitsubishi Electric QH42P?
The Mitsubishi Electric QH42P is a I/O in the MELSEC-Q Series. DC input: 32 points, 24 V DC, 4 mA, response time: 1/5/10/20/70 ms, 32 points/common, positive common type, transistor output: 32 points, 12...24 V DC, 0.1 A/point, 2 A/common, response time: 1 ms, 32 points/common, sink type, 40-pin connector x 2, number of occupied I/O points: 32 points. Mitsubishi Electric has announced its discontinuation (2029/09 To be end of order) — plan spares now; PartnerPLC also sources it on the surplus market after the end of order. Specifications and manuals below are Mitsubishi Electric's own data.
