3 Reset Ratio 0.90.97
4 Modification errors ≤2%
5 Power consumption 4W.
6 Contact capacity
Signal contact :30VDC 5A;250VAC 5A
Main contact: 250VAC COS=1.0 5A
250VDC making 5A
250VDC τ=5mS breaking 500W
8 Insulation resistance
Relay’s every electric terminals are connected together. To the non-electrification metallicoutside part
or shell, its insulated resistance is less than 300MΩ measured by tramegger with opening voltage is 500V.
9 Medium intensity
Relay’s every electric terminals are connected together. And it can endure a 2000Vand 50Hz AC
voltage(virtual value) to the non-electrification metallic outside partor shell. There is no insulated breakdown
or flashover phenomenon
10 Anti-disturb capability Relay’s anti-disturb is accord with DL478-92 (<<Static Relay Protection and Security Auto-device currency Tech>>)
