Product Features
JWXC-1700 type infinite relay (hereinafter referred to as relay) is used as a general relay in the signal circuit.
Features
1. The relay is a heavy elastic DC electromagnetic relay, which uses the principle of "constant gravity" to force the moving and closing contacts to open when the coil is de-energized.
2. It adopts silver-silver oxide contact, which has the characteristics of strong anti-adhesion and low contact resistance.
3. The magnetic circuit adopts electromagnetic pure iron material with small residual magnetism, and installs the stop piece at the closed position of the armature and the iron core to ensure the minimum air gap of the magnetic circuit, prevent the ferromagnetic parts of the magnetic circuit from magnetization, and ensure the reliable fall of the relay.
4. The contact system is composed of ordinary contacts, with eight groups of common contacts for switching on and off.
5. The rated voltage of the relay is DC 24V.
