NOTES:

1. The range of coil current is

15% for AC

(60 Hz), and

10% for DC, at 20

2. The relay is applicable to the range of

80 % to 110% of the nominal coil voltage.

However, it is recommended that the relay

be used in the range of 85% to 110% to

take temporary voltage variations into

consideration.

3. The coil resistance of DC types is the

measured value at a coil temperature of

C. Please compensate coil resistance

0.4% for each degree centigrade coil

temperature change.

4. All AC 240 V types are rated for double

coil voltages, both AC 220 V and AC 240 V.

5. For use with 220 V or 240 V DC, con-

nect a resistor as suggested in the chart

below, in series with the 110 V DC relay.
