FEATURES/BENEFITS
• Mounting and dismounting on DIN rail without
any tool or directly mountable on panel
• Zero-cross and random models; thyristors output
• Large control range
• Green control LED
• Very high immunity
• Low leakage current
• Internal transient suppression
DESCRIPTION
The Series DRL single-phase DIN-rail relays are
designed for all types of loads. The relays utilize
optical isolation to protect the control from load
transients. DRL 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 DRL 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
position
(80mm)
figure on the right). In case of zero 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 DRL 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
nominal current 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
1~
short-circuit of the load, use a fuse with a I2t
Fuse

value = 1/2 I t value.
5. EMC:
Immunity: lmmunity levels of the DRL comply
L1
with EN61000-4-4 &5.
Emission: The system integrator must ensure
that systems containing SSRs comply with the
requirements of any rules and regulations
applicable at the system level. The very low
T1
zero-cross voltage (<20V) improves the
conducted emission level in comparison with
