Information
This product is part of Smart Relay - Zelio Logic SR2/SR3, an offer of simple automation systems from 10 to 40 I/Os. This Zelio Logic compact smart relay features 20 I/Os, 0 to 240 with ladder and 0 to 500 with FBD programming control scheme lines. It is a module with rated supply voltage of 24V AC and cycle time of 6ms to 90ms. It offers 12 discrete inputs with voltage of 24V AC and 4 relay outputs with voltage range from 24V to 250V AC and 5V to 30V DC. It is an IP20 and IP40 rated product. It weighs 0.35kg. The main application of this module is industry and building/service sector. This product is certified by C-Tick, GL, UL, CSA and GOST. It meets EN/IEC 60068-2-6 Fc and EN/IEC 61000-4-11 standards. Easy to use, Zelio Logic provides a real alternative solutions based on cabled logic or specific cards.
