Replacing Relays
Reference Data
To replace output relays, first remove the cover using the following procedure.
(1) Hook your fingers under the handle and bend it upwards.
(2) The side will bend
out in the direction
of the arrow,
releasing the hook.
The following reference data shows actual measured data from sampling in a
production line. There is some variation in relay characteristics, so use this
data for reference only.
