the output connection.
Output current
Output current is 3A per point to drive resistance load for voltage below AC250V.
Inductance load is below 80VA (AC100V or AC200V) and lamp load is below 100W (AC100V
or AC200V).
Open leakage current
There is no leakage current when output point is OFF, it can drive neon light.
Use life of relay output point
The standard life of inductance load such as contactor, solenoid valve: according to our
experiment results, 20VA load is about 3 million times, 35VA load is about 1 million times,
80VA load is about 0.2 million times. However, the life will extend if parallel connect surge
absorber with the load.
Note: T type (Y0, Y1) has no relay output, do not connect AC220V, or the product will be broken.
◆ For DC inductance load, please parallel connect with commutate diode. If not connect with the
commutate diode, the point’s life will be decreased greatly. Please choose the commutate diode
which allow inverse voltage endurance up to 5~10 times of the load’s voltage, ordinal current
exceeds load current.
◆ Parallel connect AC inductance load with surge absorber can reduce noise and extend useful
life of the points.
