- قدرة الاتصال: ≤12A for resistive loads, ≤6A for inductive loads (50% derating recommended)
- Socket Matching: Only use RXZE series sockets; do not mix other brands
- Test Button Note: Unlock the lockable button after use to avoid wrong fault judgment
- LED Indication Rule: 2 = with LED, 1 = without LED, select according to on-site demand
ملخص: RXM2AB2P7 is a stable and fully-functional miniature intermediate relay suitable for most industrial control occasions. Focus on contact quantity, coil voltage and load type during selection. Equipped with matched sockets and accessories, it greatly improves system reliability and maintenance convenience.
