KINCO K631-04IV PLC

Kinco K631-04IV is an analog expansion module for Kinco K6 series PLCs, designed to connect sensors and field devices with standard current and voltage signals. It is used in automation systems where 4 analog channels are required for pressure, level, flow, temperature, weighing, and other transmitters with 4–20 mA, 0–20 mA, 1–5 V, or 0–10 V outputs. The K6 platform officially supports up to 14 expansion modules per CPU. (en.kinco.cn)

The K631-04IV provides 4 analog inputs and is intended specifically for current or voltage measurement. Technical references for this module list the supported input ranges as 4–20 mA, 0–20 mA, 1–5 VDC, and 0–10 VDC, with measurement accuracy of ±0.3% F.S. Secondary spec sheets also state 12-bit conversion for high-resolution measurement. (anaheimautomation.com)

Short description:
Kinco K631-04IV is a practical module for expanding the analog capability of a K6 PLC system. It allows a controller to receive standard industrial analog signals and use them in control logic, HMI displays, and supervisory systems. The module is well suited for dosing systems, pumping stations, hopper and weighing applications, HVAC, water treatment, and other tasks where continuous process variables must be monitored. Kinco’s own materials describe K6 as the upgraded family succeeding part of the older K5 platform. (en.kinco.cn)
