LU-S14052 8-Channel Isolated Digital Input Module
The LU-S14052 provides eight mutually fully isolated digital input channels supporting wet contacts, with a high level of +3V to +30V and a low level of 0 to +1V. Isolation voltage is 5000V and input impedance is 3Kohm/0.5W. Modbus protocol over an RS-485 bus is supported, with built-in optical isolation providing 3000V isolation voltage, plus surge protection, transient absorption and lightning protection.
Overview
LU-S14052 provides 8 fully isolated digital input channels and supports wet contacts, with a high level range of +3.V~+30V and a low level range of 0~+1V. Isolation voltage 5000V, input impedance 3KΩ/0.5W. 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.
