LU-S14024 Four-Channel Analog Output Module
The LU-S14024 is a four-channel analog output module with 12-bit resolution, providing 0-20mA, 4-20mA and -10 to 10V output ranges. Voltage or current slew rate and start-up output are programmable, and output values can be changed via communication. It also has four digital inputs usable as counters or for transient response on each output channel; the counters measure external low pulses up to 65,535 counts, readable by the host.
Overview
LU-S14024 is a four-channel analog output module with 12-bit resolution, capable of 0~20mA, 4~20mA and -10~10V 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. It also has 4 digital inputs, which can be used as counters or for transient response corresponding to each output channel. The counter can measure external low pulses with a maximum count of 65535, which can be read out by the host and is automatically cleared each time the module is restarted or powered up. The transient response can automatically control the preset D/A output value when the digital input changes. In addition, 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.
