LU-S14000 Series I/O Modules

Overview
LU-S14021 is a single-channel analog output module with 12-bit resolution, capable of 0~20mA, 4~20mA and 0~10V output ranges. The setting rate of voltage or current and the initial output at startup are programmable, and the output magnitude can be changed via communication. A voltage isolation of 3000V is provided between the output channels and the module, effectively preventing the module from being damaged by high-voltage surges. It supports the Modbus protocol and uses the RS-485 bus for communication transmission, with a built-in optocoupler providing 3000V isolation voltage. It features surge protection, spike absorption and lightning protection.
