The JXK-21 Hall current transmitter is specifically engineered to convert small current signals within the 0–20A range, making it an ideal solution for control cabinets, compact equipment boxes, and low-power industrial circuits. Unlike standard high-current monitors that are often oversized and lack sensitivity for minor loads, this transmitter focuses entirely on lower-current monitoring precision.
To address the spatial constraints of modern industrial environments, the JXK-21 current transmitter utilizes a streamlined terminal-input structure. This design effectively replaces the traditional, large through-hole opening with a direct conductor connection system. By landing the current wiring directly onto the module's terminals, the device can be installed neatly alongside terminal blocks, relays, and other standard DIN rail components.
System integration often involves varying power architectures, which is why the JXK-21 is designed with versatile DC24V and AC220V power supply options. This flexibility allows the transmitter to natively match the most common control-cabinet power systems found in industrial automation. While many modern panels utilize a standard 24VDC instrumentation supply, numerous auxiliary devices and legacy systems still rely on AC220V power.
