The Pharos RIO 80, 44 and 08 (Remote Input Output) devices provide a convenient and scalable way to add inputs and outputs to a Pharos system for show control and integration. Each device can be placed where it is needed and connected to the Controllers over an Ethernet network. Each RIO has a multi-protocol serial port, supporting DMX output, and a combination of multi-functional digital/analog inputs and relay outputs.

The RIO is Power-over-Ethernet (PoE) powered, with a rugged DIN rail mounting enclosure and install-friendly connectors. It comes in three variants – one with eight inputs; one with eight outputs; and one with four of each. The inputs are individually configurable as contact closure, active low, active high or 0-24V analog level. The outputs relays (rated 48V, 0.25A) are individually isolated (1kV) from each other and all other ports. All variants support a multi-protocol serial port.

Remote Devices allow the fully scalable Pharos system to be tailored to the needs of each individual project. Multiple Pharos Controllers can be used together with up to 200 Remote Devices and will synchronise automatically. The Controllers are programmed using the free Pharos Designer 2 software.

  • Power-over-Ethernet (PoE) powered device allows show control inputs and outputs to be placed at any remote location on a network
  • Compatible with all Pharos Controllers (LPCs, AVC) allowing lighting and AV to respond instantly to the environment for interactive installations
  • Any number of RIO devices can be placed on a network as part of a distributed system utilising PoE technology to facilitate a familiar, simple and reliable CAT5 wiring topology
  • Supports a variety of show control protocols that make it trivial to interface to third-party systems
  • Integrated bi-directional RS232/RS485 serial port, including DMX output
  • Three models available: RIO 80 (8 inputs configured as contact closures, digital or analogue inputs), RIO 44 (4 inputs configured as contact closures, digital or analogue inputs; 4 isolated relay outputs), RIO 08 (8 isolated relay outputs)
