LS IS AI 4-20MA HART KL3101X1-LS1 | Emerson

Description

LS IS AI 4-20MA HART KL3101X1-LS1 is an Emerson analog input module designed for industrial process automation, supporting 4-20mA analog signals and HART two-way digital communication. Based on comparable industry products, key specifications include: a power supply range of 20 to 35V DC with reverse polarity protection, and a maximum operating current of 25mA. It features high output accuracy of 0.1% F.S. and a fast response time of 2ms to reach 90% of the final value. The module supports HART signal bidirectional transmission, with a load resistance of up to 550 ohms for 4-20mA signals and a minimum load resistance of 250 ohms for HART communication. It operates in a temperature range of -40 degrees Celsius to 75 degrees Celsius, with optional extended process temperature ranges from -106 degrees Celsius to 815 degrees Celsius depending on probe configuration. The unit has an explosion-proof certification of [Ex ia Ga] IIC, a protection rating of IP20, and mounts on a standard 35mm rail. It offers isolation between intrinsic safety and non-intrinsic safety ends, with insulation resistance of at least 100M ohms, and complies with industrial electromagnetic compatibility standards. This module is ideal for hazardous area process monitoring applications requiring reliable analog and digital signal transmission.
