Description

The Open Control System Controller is a fully programmable controller that is intended for Building Lighting Control System. The Controller being fully programmable will ensure control & monitoring application versatility, allowing specific application to be created according to each facility or application requirement. The controller is a fully configurable controller based on the PIC series micro-controller with an on-board clock and two RS-485 communications Bus. The six digital outputs 240VAC relays (16 Amps) are ideal for driving contractors and lighting circuit directly. The two analog outputs (0 – 10 VDC or 4 – 20 mA) are used for lighting dimming control via conventional dimmer. The six digital inputs are be used for pulse counting and reading contact closures directly. The two analog inputs are be used for reading the lux sensor, 4 to 20mA and 0 to 10VDC input signals.
