WHERE
TO USE
GE
Timing relays are used for motor acceleration, sequence
interlocking, and other applications requiring delayed
opening or closing of control circuits. GE Relays
operate on the flux-decay principle—dropout
being delayed by slowing the rate of flux decay.
Nonmagnetic armature shims of different thickness
provide differing lengths of time delay. Some final
adjustment can be made by varying tension of the
armature spring.
Choose
GE IC2820A100A relays for two circuits and minimum
mounting space. Choose GE IC2820A100B relays for
either two or four circuits and added time delay.
Choose
between completely assembled relays and building-block
units on the basis of purchasing perference. If
applications can be predicted, completely assembled
relays may be desired. If applications vary in number
of circuits and arrangement, building-block forms
may be more economical and practical. |
