Solid State Relays Zero Switching Type RMD Hybrid Relay * Hybrid Relay: SSR + EMR combination * Current rating @ 60C: 30 AAC, 40 AAC * Nominal voltage ratings: 240 VAC, 227 VAC/ 480 VAC + Neutral * Control voltage: 24 VAC, 120 VAC, 240 VAC * Mercury-free, leading to a safer environment * Similar mounting to mercury relays * RoHS compliant * Switching with arc-free operation * Switching rate: up to 20 cycles per minute * Operating life: 4 million operating cycles Product Description Ordering Key third one is directly conneced between the L2 and the T2 terminals. This hybrid relay also provides a solution which does not contain mercury and is RoHS compliant. The maximum current reached per pole is 40AAC in a surrounding temperature of 60C (140F). RMD3H combines the benefits of solid state relays and electromechanical relays to provide a hybrid relay. This means that there is virtually no contact arcing and much less heat emission inside the panel. RMD3H switches heaters on three legs while RMD2H has two poles which are switched and the RMD 3 H 48 HA 40 Hybrid Relay Number of poles Platform Rated Voltage Control voltage Rated Operational current Selection Guide Rated Voltage Blocking Voltage Number of switched Poles Rated Control Voltage Rated operational current at 60C surrounding temperature 30 Arms 40 Arms 2 24 VAC/DC RMD2H24LA30 RMD2H24LA40 (1phase loads) 120 VAC RMD2H24MA30 RMD2H24MA40 (3phase delta) 240 VAC RMD2H24HA30 RMD2H24HA40 24 VAC/ DC RMD3H24LA30 RMD3H24LA40 120 VAC RMD3H24MA30 RMD3H24MA40 240 VAC RMD3H24HA30 RMD3H24HA40 24 VAC/ DC RMD3H48LA30 RMD3H48LA40 120 VAC RMD3H48MA30 RMD3H48MA40 240 VAC RMD3H48HA30 RMD3H48HA40 240Vrms 240Vrms 600Vp 600Vp 3 (3phase delta) 480Vrms 600Vp 3 (3phase star+Neutral) General Specifications Operational voltage Range Non-rep peak voltage Operational frequency range Power factor CE marking Finger Protection Operating life Control input status Varistor protection across outputs Pollution degree Over-voltage category Isolation - input to Output RoHS compliance RMD..24 RMD..48 240 VAC -15% / +10% 277 VAC (480 VAC with neutral connection) -15%/+10% 600 Vp 45 - 65Hz > 0.90 Yes IP20 4 million cycles continuously ON Green LED when control input is applied 420V 2 (non-conductive pollution with possibilities of condensation) III (fixed installations) 4000Vrms YES Specifications are subject to change without notice (18.01.2010) 1 RMD3H48HA40 Input Specifications Rated Control voltage range Pick-up voltage Drop-out voltage Maximum Input current Response time pick-up ZC Response time drop-out RMD..LA RMD..MA RMD..HA.. 24 VAC/DC +10/-15% 15 VAC/ 9 VDC 15 VAC/ 9 VDC 400 mA 0.5 cycle 2 cycles 120 VAC +10/-15% 36 VAC 36 VAC 400 mA 0.5 cycle 2 cycles 240 VAC +10/-15% 90 VAC 90 VAC 400 mA 0.5 cycle 2 cycles Output Specifications Rated operational current (see derating curve) Min. operational current RMD..30 RMD..40 30 AAC 150 mA 40 AAC 150 mA Derating Curves 44 42 RMD..40 with AWG8 40 RMD..40 with AWG6 Current Rating (AAC) 38 36 34 32 RMD..30 with AWG8 30 28 26 24 22 20 20C/68F 30C/86F 40C/104F 50C/122F 60C/140F 70C/158F Surrounding Temperature 2 Specifications are subject to change without notice (18.01.2010) RMD3H48HA40 Agency Approvals & EMC CE marking Low Voltage Directive EMC Immunity EMC Emission Electrostatic Discharge (ESD) Immunity Electrical Fast Transient Burst Immunity Output Input Electrical Surge Immunity Output, line to line Output, line to earth Input, line to line Intput, line to earth Radio Interference field emissions (radiated) IEC / EN 60947-4-3 IEC / EN 61000-6-3 IEC / EN 61000-6-1 IEC / EN 61000-4-2 8kV, PC2 Air discharge 4kV, PC2 Contact IEC / EN 61000-4-4 2kV, performance criteria 1kV, performance criteria IEC / EN 61000-4-5 1kV, performance criteria 2kV, performance criteria 1kV, performance criteria 2kV, performance criteria IEC / EN 55011 Class B (light industry) 1 1 1 1 2 2 Approvals Endurance Test Restrictions of hazardous substances Radiated Radio Frequency Immunity 10 V/m, 80 - 1000 MHz, 1.4 - 2.0 GHz 1 V/m, 2.0 - 2.7 GHz Conducted Radio Frequency Immunity 10V/m, 0.15 - 80 MHz Voltage Dips Immunity 0% for 10ms/20ms, 70% for 500ms 40% for 200ms Voltage Interruptions Immunity 0% for 5000ms Radio Interference voltage emissions (conducted) cURus (E80573) 100,000 cycle as per UL508 RoHS EN 61000-4-3 Performance criteria 1 Performance criteria 1 IEC / EN 61000-4-6 Performance criteria 1 IEC / EN 61000-4-11 Performance criteria 2 Performance criteria 3 IEC / EN 61000-4-11 Performance criteria 3 EC / EN 55011 Class A (industrial) Connection Specifications Connection Type Illustration of terminal Power Connection Screw terminal Terminal Designations Rigid (Solid or Stranded) 1L1, 2T1, 3L2, 4T2, 5L3, 6T3, 7N A1, A2 1 x (2.5-16)mm N/A 1 x (14-6)AWG 18 in lb (2.1Nm) N/A No. 10 screw 6.35mm (1/4 inch) FASTON Max 13.5mm for ring and fork/spade termination lugs Tightening torque Size Aperture for termination lug Control Connection FASTON terminal Housing Specifications Environmental Specifications Weight Housing Material Flame class Dimensions (w x h x d) (without input connector) Operating Temperature Storage Temperature Humidity Impact resistance approx. 360g PA66 UL94V0 0 to 70C 0 to 100C 95% RH, non condensing @ 40C 15/11 g/ms 105 x 45 x 90 mm Specifications are subject to change without notice (18.01.2010) 3 RMD3H48HA40 Connection Diagrams RMD2H 240 VAC Line to line voltage: 240 VAC L1 L2 N L L3 L1 L2 L3 T1 T2 T3 N N L1 L2 L3 T1 T2 T3 2pole, 1 phase switching RMD2H24.. 3pole, 2 phase switching - RMD2H24.. 240V heaters connected in Delta, with 240V 3-phase supply.

WARNING: Internal power supply in RMD2H and RMD3H24 is taken through terminals L1-L3, while for RMD3H48 it is taken through L1-N. If these are not connected correctly, the internal bypass relays will not work. The `N' terminal must be left unconnected for RMD2H and RMD3H24. 4 Specifications are subject to change without notice (18.01.2010) RMD3H48HA40 Dimensions (mm) 140.7 48.5 82.6 97 14.9 6.35 50.7 24.7 82.6 97 Specifications are subject to change without notice (18.01.2010) 5
