Product Description

The KRT-SN-20A module, part of the SN series control relay family, is a 20A industrial sensor designed for robust automation applications. It features 16 digital inputs and 8 relay outputs, supporting direct integration with up to 4 expansion modules via its modular interface. Equipped with RS-485 and Ethernet communication, the device operates within a 24VDC voltage range (-15% to +20% tolerance) and withstands industrial temperatures from -20°C to 60°C. Widely used in manufacturing, energy systems, and process automation, this sensor offers high durability, noise immunity, and a compact IP65-rated housing. Its 500mAh backup battery ensures short-term power resilience, while the optional 4.3-inch HMI screen (model-specific) enables localized monitoring. The module achieves a 20-meter detection range for proximity sensing, though installation requires technical expertise for optimal performance.
