I. Overview
JY-8 series of static voltage relay voltage relay for the
introduction of integrated circuits (hereinafter referred to as the
relay) for the generators, transformers and transmission line
protection devices, as over-voltage protection, or blocking the
action of low-voltage components .
Imported digital relay switch, new switching power supply module
and imported intermediate relay, advanced electronic circuit
design, reasonable structure, China is currently the best
replacement products. The relay has the following distinctive
features:
1, the use of digital code switch operation voltage setting.
Intuitively easy setting to change the value without setting the
school inspection.
2, the relay for the integrated circuit static type, high accuracy,
setting error is less, less power consumption, no heat phenomenon.
3, Fast time, the return factor, wide tuning range.
4, high reliability, no shaking.
5, the relay terminal block dimensions and the base of the original
size of the electromagnetic type, terminal blocks and the same
shape, can completely replace the DJ, DY type voltage relay.
