Tender Specification: SLC-RC Switch203-C RS485 ext.

Description:
Switching controller with external antenna as an intelligent replacement for conventional ring control receivers, enabling the independent switching of up to three phases.

Manufacturer: 	esave AG
Type: 	SLC-RC Switch203-C RS485 ext.
	or approved equivalent
Certifications: 	CE 

Function:
Switching controller designed to replace conventional ring control receivers in lighting installations. Enables the independent switching of up to three phases. Switching operations can be controlled according to ambient brightness, predefined schedules, external inputs or the integrated astronomical clock.

Measurement and control data from connected devices can be processed directly through the self-organizing 2.4 GHz mesh network. The integrated eSIM enables remote monitoring and gateway operation for up to 100 additional controllers.

Configuration and monitoring can be performed locally on site or remotely via cellular connection and the SL-Control web platform.
