Description

This product is part of the Zelio Logic range, an offer of smart relays for simple automation systems from 10 to 40 I/Os. The analogue I/O extension module provides 2 input/outputs. It is an extension module with an analogue output range of 0 to 10V and a maximum load current of 10mA for analogue output. It provides 10bit on the input range and 10bit on the output range. The temperature probe is Pt 100, 3-wire conforming to IEC 751. It is furnished with screw terminal for electrical connections. It is an IP20 and IP40 rated product. It weighs 0.11kg. This product meets EN/IEC 61000-4-12, EN/IEC 61000-4-5, EN/IEC 61000-4-3, EN/IEC 61000-4-4 level 3, EN/IEC 61000-4-6 level 3, EN/IEC 61000-4-2 level 3, EN/IEC 60068-2-6 Fc, EN/IEC 61000-4-11 and EN/IEC 60068-2-27 Ea standards. Simple to select, install and program, Zelio Logic is suitable for all your applications. Flexible, it offers you the choice of 2 ranges, compact or modular, extendable and 2 programming languages (FBD or LADDER). Easy to use, Zelio Logic provides a real alternative to solutions based on cabled logic or specific cards.

Features

The Schneider Electric SR3XT43BD is engineered exclusively for seamless, plug-and-play physical and electrical integration with the Zelio Logic SR3 modular smart relay series powered by a 24V DC supply. This matching architecture eliminates industrial communication bottleneck risks and complex configurations, allowing control engineers to instantly scale their existing automation footprint without upgrading to an expensive high-end PLC.
This high-density expansion module provides exactly 4 analog I/Os, consisting of 2 analog inputs and 2 analog outputs, to bridge the gap between your modular controller and field instrumentation. It features built-in short-circuit protection on the outputs, preventing catastrophic electrical damage to your control loop during field wiring mishaps or sensor failures.
To tackle varying industrial instrument signals, the two inputs offer exceptional field flexibility, supporting 0 10V voltage modes, 0 20mA current loops, and direct 3-wire Pt100 temperature probes conforming to IEC 751. The dual analog outputs deliver a stable 0 10V signal with a 10mA maximum load current, meaning you can comfortably drive variable frequency drives (VFDs), proportional valves, and process indicators without needing external signal conditioners.
Equipped with an optimized 10-bit resolution across both input and output ranges, this module delivers crisp, reliable granularity such as a 9.8 mV LSB value on 0 10V ranges and a 0.15 C resolution for temperature monitoring. Combined with a tight conversion error threshold of +/- 1% of the full-scale value, it guarantees the highly repeatable measurement accuracy demanded by commercial HVAC, pumping, and material handling systems.
Designed with space-saving efficiency in mind, this compact module measures just 35.5 mm wide, mounting instantly onto standard 35mm DIN rails via built-in retractable lugs. Heavy-duty integrated screw terminals accommodate solid or flexible wire sizes ranging from AWG 24 to AWG 14, streamlining field terminations while assuring rugged, vibration-resistant connections under continuous industrial operation.
Built to thrive in demanding operating environments, the module features a robust IP20 terminal block rating and an IP40 front panel enclosure rating to shield internal components from dust and debris. It operates flawlessly across a wide temperature window from -20 C to 55 C (-4 F to 131 F) and carries global industrial certifications including UL, CSA, C-Tick, and GOST ensuring your control panel satisfies stringent regulatory compliance audits right out of the box.
