MSN-103.D

The MSN-103.D is a small, strong, and high-quality relay module. It works well in many electrical control systems. It runs on a 24 VDC coil and has one changeover contact (1CO). This contact can switch currents up to 6A. Although it’s small, the relay is tough and accurate. Its slim 6.2 mm design fits easily into tight spaces. So, it’s perfect for control panels with limited room. You can quickly mount it using a standard DIN rail clip. No special tools are needed.

The relay stands out because of its great insulation. It offers 1000 VAC between contacts and 4000 VAC between the coil and contacts. That keeps your system safe. It also lasts a long time. The relay works up to 10 million times mechanically. Electrically, it performs well for up to 30,000 cycles. This makes it a smart and reliable choice. Plus, it includes an LED light. This shows you the relay’s status right away. So, you can troubleshoot faster.

The contact is made from silver-nickel (AgNi). This gives good conductivity and a long life. Even better, the switching speed is fast. It turns on in just 7 ms and off in 15 ms. With all these strong features, this relay is built for performance and durability.
