Solenoid valve wiring method
Solenoid valve wiring method:
According to the wiring method, there are two commonly used
Solenoid valve wiring methods: lead wire type and junction box type. The principle is the same. The lead type is actually to unplug the junction box and connect a power line from the coil to form an integrated type.
Lead type; mostly used for waterproof and explosion-proof (explosion-proof) types. The advantage is that the leads can be connected directly to the control system.
Junction box type; currently the most popular is this wiring method, using DIN connectors, the control system will not be affected no matter how far it goes, there will be no breaks in the middle, and no nodes will be added.
According to the coil type, there are three common types: single-coil switch control type (90% on the market), single-coil self-holding type and double-coil self-holding type.
Single-coil switch control wiring, this is the most common, whether it is lead-type or junction box-type building automation solenoid water valve wiring, it is all three-wire.
If it is direct current such as control line, positive line, negative line, ground line, etc., there is no distinction between positive and negative poles, remember that there is no distinction between positive and negative poles.
