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 Figure 1 — DRD relay; dimensions in inches (mm) APPROVALS Series DRD relays are pending UL recognition.

Dismounting 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. L1 L2 Emission: The system integrator must ensure that systems containing SSRs comply with the requirements of any rules and regulations T1 T2 applicable at the system level. The very low zero-cross voltage (<20V) improves the conducted emission level in comparison with – + – + most SSRs with zero-cross voltage higher A2 A1 A2 A1 control 1 control 2 than 50V. Load 6.
