DESCRIPTION
The Series DR single-phase DIN-rail relays are
designed for all types of loads. The relays utilize
optical isolation to protect the control from load
transients. DR 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.
APPLICATIONS
• Heating control
• Motor control
• Industrial and process control
APPROVALS
Series DR relays are pending UL recognition.

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: Only in 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 derated by 50% .
The SSR requires air convection. Lack
of air convection produces an abnormal
heating. Keep a distance between the
upper SSR and the lower SSR (see
vertical
3.15 inches
figure on the right). In case of zero
position
(80mm)
space between two SSRs, reduce the
load current. It’s suggested to maintain
the heat sink temperature under 90°C.
Forced cooling significantly improves
the thermal performances.
3. Typical application loads: The DR relay
may handle motor and resistive loads.
For different loads, check the inrush
current at turn-ON and possible overvoltages at turn-OFF or contact
the factory.
• Incandescent lamps — Inrush current is generally 10 times the
current nominal for 10ms.
• Electric discharge lamp — These loads often have overcurrent at
turn-ON and overvoltage at turn-OFF. Use 480Vac SSR on 240Vac
mains.
• Transformer loads — Very high inrush current, up to 100 times the
nominal current.
• Capacitive loads — Very high current at turn-On and overvoltage at
turn-Off. Use only zero-cross models.
4. Protection: To protect the SSR against a short-circuit
1~
of the load, use a fuse with a I2t value = 1/2 I2t value.
Fuse
5. EMC:
Immunity: lmmunity levels of the DR comply with
EN61000-4-4 &5.
L1
Emission: The system integrator must ensure that
systems containing SSRs comply with the
requirements of any rules and regulations applicable
T1
at the system level. The very low zero-cross voltage
+
(<20V) improves the conducted emission level in
Load
–
comparison with most SSRs with zero-cross voltage
higher than 50V.
