MECHANICAL SPECIFICATION
DESCRIPTION
The Series DRD dual-output DIN-rail relays are
designed for all types of loads. The relays utilize
optical isolation to protect the control from load
transients. The DRD relays have an integral heat sink,
and can be mounted and dismounted onto a DIN rail
without any tools. The relays may also be panel
mounted. All relays offer a green control LED and
transient suppression. This dual package allows
users to conserve cabinet space.
APPLICATIONS
• Heating control
• Motor control
• Industrial and process control

DIN-RAIL MOUNTING

NOTES:
1. Connections: For output terminals, the wire cross sections must be
adapted to the load current and to the overcurrent protection device
characteristics. The relay rated voltage must be adapted to the mains
rated voltage. These relays use screw clamp connections.
2. Mounting: Should be in the vertical
position. Protect heat-sensitive
materials as well as people from contact
with the heat sink. For non-vertical
mounting, the load current must be 50%
derated. The SSR needs air convection
through the heat sink. Lack of air
convection produces abnormal heating.
Keep a distance between the upper
vertical
3.15 inches
position
(80mm)
SSR and the lower SSR (see figure on
the right). In case of zero space
between two SSRs, reduce the load
current. It’s suggested to keep the heat
sink temperature under 90°C. Forced
cooling significantly improves the
thermal performance.
3. Typical application loads: The DRD
relay is designed for resistive and motor loads. For other loads, check
the inrush current at turn-ON and possible
3~
1~ 2~
overvoltages at turn-OFF or contact factory.
4. Protection: To protect the SSR against a
Fuse
2
short-circuit of the load, use a fuse with a I t
value = 1/2 I2t value.
5. EMC:
Immunity: lmmunity levels of the DRD comply
with EN61000-4-4 & 5.

Emission: The system integrator must ensure
