DR22 Series Solid State Relays
Series
Crydom DR22 Series Solid State Relays were developed to offer the advantages of
semiconductor switching technology in a standard 22.5 mm industrial package. Quick and easy
installation is coupled with low drive power requirements and efficient, reliable power SCR
output. This compact new design offers up to 35 ARMS in ambient temperatures of 40ºC.

♦LED indicates only input status. It does not
represent output status.
♦To achieve maximum ratings, there must be a
minimum spacing of 0.89 in (22.5 mm) between the
devices in free air (as shown in fig.2).

♦Protective Earth (PE) screw type recommended is
10-32 UNC standard, not provided with SSR. Through
the use of a DIN rail ground (protective conductor)
terminal block, the DIN rail itself can be used as the
grounding bus bar. In this case, the zinc plated steel
material used for the DIN rail clip of DR22 models,
permits a secure path to ground and avoid the need of
a further PE connection (see fig.3).

General Notes
(A) Load can be wired to either terminal 1 or terminal 2. Proper polarity must be observed for the DC control power supply, with terminal 3 being positive with respect to terminal 4.
(B) DC inductive loads must be diode suppressed.
(C) AC input models operating range is -20 to 60 ºC
