140ARI03010 Schneider Relay Module
140ARI03010 is an automation product launched by Schneider Electric, belonging to the analog input module. It has a modular design and supports multiple signal access methods (such as 2-wire, 3-wire, and 4-wire RTD signals). It is suitable for the acquisition and processing of analog signals in industrial automation systems and can be integrated into DCS distributed control systems or PLC programmable controller architectures. It serves as the core input unit to achieve accurate monitoring of physical quantities such as temperature and pressure. Its high compatibility and scalability can meet the signal processing requirements of complex industrial scenarios, ensuring stable system operation.
Technical specifcations for 140ARI03010
Number of channels: 8 analog input channels.
Resolution: 13 bits, ensuring high measurement accuracy.
Supported RTD types: including Ni 100, Ni 200, Ni 500, Ni 1000, Pt 100, Pt 200, Pt 500, Pt 1000, can be connected to various types of resistance temperature detectors.
Working voltage: Usually powered by a DC power supply, the specific voltage range should refer to the product manual.
Input type: differential input, which helps improve the anti-interference ability of the signal.
Analog input range: Supports multiple current range inputs for temperature probes, such as 2.5 mA Pt 100, Pt 200, 0.5 mA Ni 100, Ni 200, Ni 500, Ni 1000, etc., to meet measurement requirements for different temperature ranges and accuracies.
Accuracy error: 0.1 ° C, linearity error+/-0.5 ° C (full range),+/-0.01%, temperature offset accuracy+/-0.9 ° C (at 0-60 ° C),+/-0.5 ° C (at 25 ° C), ensuring the accuracy of measurement results.
Insulation and isolation: The insulation between each channel and the bus is 1780 V AC (47... 63 Hz, for 60 seconds) and 2500 V DC (for 60 seconds); The isolation between channels is 300 Vrms AC, effectively preventing electrical interference.
Update time: 640 ms (2-wire/4-wire), 1200 ms (3-wire), affecting the real-time performance of data collection.
Fault type and indication: It has functions such as wire breakage sign and CE local signal. It indicates channel faults through 8 LED red lights, 8 LED green lights indicating channel opening, 1 LED red light indicating external faults, and 1 LED green light indicating bus communication in progress (active), facilitating fault diagnosis and maintenance.
Bus current requirement: 200 mA, power consumption of 1 W, affecting the power design and energy consumption of the system.
Module classification: Standard modules that comply with relevant industrial standards.
Product weight: 0.3 kg, easy to install and transport.
Environmental standards and certifications: Compliant with CSA C22.2 42 and UL 508 standards, certified by CUL and FM (Class 1, Class 2), anti-static discharge of 8 kV (broadcast, compliant with IEC 801-2), 4 kV (contact, compliant with IEC 801-2), anti electromagnetic domain of 10 V/m (80... 1000 MHz, compliant with IEC 801-3), capable of stable operation in harsh industrial environments.
