Fire contact

The device has an Override emergency dry contact port (PANIC - GND) for fire emergency applications. When receiving the fire signal from the fire control center, the device will preferentially open the first loop as an emergency lighting circuit according to the signal.

Isolated input/output channels

20 independent input/output channels form a one-to-one loop. The control of each channel loop can be configured via software, each channel has a separate transient surge protection circuit, surge protection up to 220V 25A. Each channel allows 16A resistive load current or 8A inductive load current, and supports electric curtain control and fan control.

Centralized control

The module can be managed visually and centrally through SCHIDERON Intelligent Lighting Management System (LMS). The data of each channel in the device can be uploaded into the intelligent lighting management system for device data management and status analysis. Scene management is to preset the time to the device through the LMS, and then turn on the corresponding scene mode to reach all or part of the device loop.

DIN rail mounting

“Modular” equipment is flexibly installed and applied in the actual environment. The module is mounted on a standard 35mm DIN rail, providing convenient installation and maintenance for users.

S-Net bus modular design

The module is designed for the MCU pure hardware architecture and has local data processing and channel control. The overall power consumption of the module is low and the task processing is timely. The module communicates via the dedicated bus S-Net to ensure the stability and reliability of data transmission. Each device has a corresponding physical address. The DIP dialer can be used to set the address of the module to ensure that each module can operate correctly and accurately receive and execute commands transmitted from S-Net.

The 20-way 16A relay switch module (SDR-RL-C2016) is a 20-channel relay control device for 120VAC to 240VAC for incandescent, fluorescent, neon/cold cathode, etc. 20 independent input/output isolations The channel and 20 emergency switch buttons allow manual switching of the circuit without bus devices and software. Each channel allows 16A resistive load current, or inductive load current of 8A, and supports electric curtain control and fan control. Intelligent lighting management system (LMS) can be used for independent loop control, pre-editing scene control and scene timing control. Device data can upload module local data to intelligent lighting management system (LMS) for device status management and statistical data analysis. Transmission and equipment control comply with the latest industrial industry standards.
