enAct™ 4 Channel Relay


The new series of enLight® enAct™  controllers have been designed to add control to the existing sensor and network capability of the enLight® platform. Each enAct™ device can be connected to a DOLFin® Pro for Enterprise either individually or as a cluster of devices and use the mesh network to communicate with the rest of the system as well as connecting to the BMS being used. The enAct™ range is all DIN rail mountable and includes devices for IO control, high power asset monitoring, circuit monitoring, remote switching and appliance monitoring and control.

The enAct™ 4-Channel Relay permits the switching of circuits too powerful for the enAct™ Digital IO Controller itself but uses the IO Controller for its input, enabling outputs at up to 240V AC/DC and up to 10A to be switched on each of the 4 circuits. This means that one Digital IO Controller can manage 2 x enAct 4-Channel Relays and all 3 units can be wired into just one enLight DOLFin® Pro for Enterprise for communication with the rest of the enLight® platform.

All devices in the enAct™ range come in a standard 105mm x 90mm x 60mm DIN rail mountable package for easy mounting in plant rooms or distribution cabinets and they fit most types of enclosure for both indoor and outdoor use. The enAct devices are wired into the enLight® enTalk™ network by connecting to a DOLFin® Pro for Enterprise radio node in a loop-in/loop-out configuration to support additional sensors or actuators in the same location.

The enAct 4-Channel Relay features:

  • 4 individual relays in one compact package

  • Each relay can switch up to 240V AC or DC at up to 10A

  • Pluggable terminals for easy wiring

  • Takes input from enAct 8-Ch Digital IO Controller

  •  5 year guarantee

Seamless integration with enLight lighting platform



All enAct devices are designed to work seamlessly with the enLight platform. Most of the devices can be mounted in any DIN rail enclosure using a GST mini connector for mains input. Devices providing high power output use the same GST Mini connector.

All devices include two RS485 connectors for connecting to an enLight DOLFin® Pro, leaving one socket free to connect a single or a daisy chain of other sensors or actuators – subject to total power draw.

Away from the vicinity of the mains powered enAct device, wireless enLight enSense™ devices (coming late 2017) can connect to the network via the DOLFin Pro for their data feed to be sent on to the enLight enGauge™ API.

Cost effective smart city deployment

By deploying the enLight platform on lamp posts across the city, town or campus, a whole host of smart applications can be realised by utilising the network created by the lights. Multiple wireless technologies do not need to be funded and the inherent value of the street light estate increases as it allows resource reduction or increased efficiency projects to be deployed, without the major capital cost of their own networks. The enSense sensors are fully compatible with the enLight enCore™ Management System or via other management platforms through the enLight enTalk API.
