    SC-4104-W1 is an easy-to-use smart control module. It can be used in small FCU control system and small lighting control system. SC-4104-W1 requires no specialist skill to install and operate, and no software is needed in order to control the DO channels.

    The controller module provides 1 channel for AC digital input (photo couple isolation), 1 channel for temperature detector, 1 channel for Form C relay output and 3 channels for Form A relay output. The input channel can directly control the 4-channel relay ON and OFF sequence without a remote host controller. There are total of 7 kinds relay output sequence for users to select. Every output channel supports up to 100W power consumption device.

    If required, user can control these relay output and monitor DI and temperature by communicating with the SC-4104-W1 on Modbus RTU and DCON protocol. And an added benefit is that different addresses can be set via hardware configuration. SC-4104-W1 has ±4 kV ESD protection for each terminal and 5000 Vrms intra-module isolation for DI. And the Shell is made by fireproof materials. These high protection designed allows users more at ease.
