"This product is part of the Harmony Solid State Relays range, an offer of panel mount solid state relays. The 1-phase solid state relay features zero voltage switching. It is an automation relay with a control circuit voltage of 180V to 280V AC and a switching voltage of 10V turn on and 180V turn off. This solid state modular relay operates with an output voltage of 48V to 660V AC. It offers screw terminals of 0.2mm\u00b2 to 1.3mm\u00b2, (AWG 24 to AWG 16) for input and 1.3mm\u00b2 to 5.3mm\u00b2, (AWG 16 to AWG 10) for output connections. It is an IP20 rated product. Its dimensions are 88mm (width) x 90mm (depth) x 123.8mm (height). It weighs 0.74kg. It is suitable for packaging machines, heating control, injection molding, HVAC, textile machines and medical equipment applications. This product is certified by UL, CSA, EAC and CE marking. It meets IEC 60950-1, CSA C22.2 No 14 and UL 508 standards. It supports symmetrical DIN rail mount. Harmony Solid State Relays are the complete solution for 1 phase and 3 phase, slim, modular DIN rail and panel mount offer. SSR relays offer slim interfaces, modular DIN rail and panel mount relays. A complete, innovative and compact solution for industrial applications."
