This Schneider Electric Zelio Logic SR3 Discrete I/O Extension Module Smart Relays uses a supply voltage of 12 volts direct current, has 14 inputs / outputs contact with screw-clamp terminals. This Discrete I/O Extension Module Smart Relays provides Zelio Logic relays with additional inputs and outputs. It has a compact form-factor, allowing installation on DIN rail. Simple ladder programming, adapted for non-specialists. Discovery package, coming with Zelio Soft programming software, the simplest way to learn and use this relay. Built-in EEPROM flash memory for data backup up to 10 years, easy-to-recover after a power shortage or incident. More I/O than SR2 model, for larger applications. 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 60068-2-27 Ea, EN/IEC 61000-4-5, EN/IEC 61000-4-12 and EN/IEC 61000-4-4 L3 standards. Easy to use, Zelio Logic provides a real alternative solutions based on cabled logic or specific cards.

All PLC Direct products come with a 1-year warranty. The warranty is issued by PLC Direct. Warranty coverage commences at the date of purchase. The warranty is for mechanical defects or failures not caused by human factors including but not limited to (a) incorrect installation, (b) operating the unit in sub-optimal conditions or in scenarios not recommended by the manufacturer, (c) poor unit maintenance, etc. The warranty does not cover programming or software related issues.
If the product is eligible for PLC Direct’s warranty coverage and the customer encounters an issue with the product, we will request the item is shipped to us for diagnosis and examination. Regardless of the cause of product issues, the customer will bear responsibility for the cost of shipping the unit to PLC Direct for evaluation. Where the unit was damaged by human factors, we will offer a repair or replace quote; in cases where damage was caused by human factors, the customer is responsible for the cost of shipping the repaired/replaced unit from PLC Direct to the customer. Where the unit was not damaged by human factors but is covered by PLC Direct’s warranty, we will repair or replace the unit at our cost (or, in rare cases, refund you your purchase); in such cases, PLC Direct will bear the cost of shipping the repaired or replaced product back to the customer. It is up to PLC Direct’s discretion whether to repair, replace, or refund the customer in such cases.
