The DIN-RY8-N is a 8-channel compact relay controller with load detection feature. In addition to the relay controls, RS485/RS232 looping/external control bus for connecting multiple units or controlling external device as well. Dry contact inputs are available with On-board macro/rules engine for event programming that all can be programmed into the unit that makes it a very powerful standalone multi-feature control option.

A unique feature which allows each of the load states to be detected when wired as per our wiring guidelines. This allows 2-way mechanical switches to be used in conjunction with this unit where both units act as a traditional 2-way switch. The advantage of this is that mechanical switches can always be used regardless of the state of the automation system, even if the automation system is not powered on or operational.

The unique load detection also allows the state of each load to be detected, and through our protocol, allows discrete on and off commands to be issued which automatically evaluates the state of the load first before deciding whether or not the relay needs to be switched.

On-board rules engine allows macros to be fired when events such as dry contact or load status changes are detected. Macros can be used to control multiple DIN-RY family units in the looping RS232 or RS485 chain or to send custom messages to control systems via the RS232 and RS485 ports. Programming is completed using a cross-platform (Windows & Mac) application, connected via either RS232, RS485, USB or Ethernet when using an Ethernet to serial converter such as the CommandFusion LAN Bridge or Solo products.
