f) Working position: tilt not more than 5° in any direction and no severe vibration and impact;
g) The site shall be equipped with rainproof, snow, wind and sand devices and an environment without water vapor;
h) Where there is no more serious mold;
i) Strong external magnetic induction is not allowed in the place of use.Delay range

Technical data

1. Ratings: DC 220 V, 110 V, 48 V

2.Delay setting range
a) 20 Ms-9.999s (level difference 1ms) 
b) 0.1-99.99s (level difference 10ms) 
c) 1 S-999.9s (level difference 0.1s) 
d) 10 S-9999 s(level difference 1s)

3.Operation value and return value Under the reference condition, the operation voltage of the relay shall not be greater than 70% rated voltage, and the return voltage shall not be less than 10% rated voltage.

4.Delay consistency Under the reference condition, the delay consistency of the relay is not greater than (0.1 % setting value + 3 ms).Delay consistency = maximum value of 5 measurements - minimum value of 5 measurements

5.Under the reference condition, the absolute value of the relay's delay setting error is not greater than (0.1 % setting value + 3 ms) delay average error = the average value of 5 measurements - setting value

6.Return time: Return time should be no more than 25 ms

7.Power consumption: At rated voltage, the power consumption of the relay shall not be greater than that specified in Table

Table 3 Power consumption of relay

8. Contact performance
In A dc inductive load circuit with voltage no more than 250 V and current no more than 1 A (time constant 5 ms+ 0.75 ms), the contact disconnection capacity is 30 W.

9. Dielectric strength
The electrical terminals of the relay shall be connected to the exposed non-charged metal parts or housing, and shall be able to withstand the test of 2 K V(effective value) 50 Hz AC voltage for 1 min without insulation breakdown or flashering phenomenon.

Appearance and hole size

The relay adopts an embedded insert structure. See figure 3 attached to this manual for its appearance and installation hole size.
