NEW Series DRS Single Output to 30A 510 Vac DIN-Rail Solid-State Relay with Diagnostics Part Number Description DRS24D25 25A, 280 Vac DRS48D25 25A, 510 Vac DRS48D30 30A, 510 Vac Part Number Explanation DRS Series 24 D 25 Switch Type2 Line Voltage1 Output Current - Amps NOTES 1) Line Voltage (nominal): 24 = 240 Vac, 48 = 480 Vac 2) Switch Type: D = Zero-cross turn-on MECHANICAL SPECIFICATION FEATURES/BENEFITS • Easy mounting and dismounting on DIN rail without any tools or directly mountable on panel • Diagnostics offer control and output status • Tight zero-cross window for low EMI • 50A back-to-back thyristors • LEDs for visual diagnostics • Switch ON in case of overvoltage (DRS24D25) • Large control range DESCRIPTION The Series DRS single-phase DIN-rail relays with diagnostics are designed for all types of loads. The relays utilize optical isolation to protect the control from load transients. DRS 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 control LED and output LED for visual diagnostics. The DRS provides control and output transient suppression. A normally closed status output signal is provided for system diagnostics. The output will turn on for a short time to clamp high voltage surges.

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 vertical 3.15 inches load current must be derated by 50%. position (80mm) 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 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 DRS relay may handle motor and resistive loads. For different loads, check the inrush current at turnON 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 Fuse + and overvoltage at turn-Off. Use only zero-cross models. – 4. Protection: To protect the SSR against a short2 circuit of the load, use a fuse with a I t value = 1/2 L1 Diag L1 Diag I2t value. 5. EMC: Immunity: lmmunity levels of the DRS comply with EN61000-4-4 &5. T1 + T1 Emission: The system integrator must ensure that – systems containing SSRs comply with the – + – + requirements of any rules and regulations A1 A2 A1 A2 control control applicable at the system level. The very low zerocross voltage (<20V) improves the conducted Load emission level in comparison with most SSRs with zero-cross voltage higher than 50V. N N 6.
