Relay Box 8 | CONTEG

Relay Box 8

Relay Box 8 creates 8 relay outputs on a single intelligent port.

The Relay Box 8 is a specially designed multi-port relay for advanced process control. The Relay Box 8 is easily controlled by any RAMOS sensors or detectors. The relay can provide automatic responses to sensor status changes. Setting up the Relay Box 8 is easy thanks to its built-in auto-sense feature and user-friendly web interface.

The automatic response to sensor changes gives users more flexibility when responding to environmental alerts. The automatic response eliminates the need for user intervention during the alarm condition, as it will automatically switch On/Off crucial equipment thus avoiding any substantial damage.
