Pharos RIO (4 Input & Output)

RIO 44

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 Designer system for show control and integration.

Each device can be placed where it is needed and connected to the Pharos Designer range of 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.

  • Install is easy and convenient with just a single Power-over-Ethernet (PoE) network connection.
  • Rugged DIN rail mounting enclosure and install-friendly connectors.
  • 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 Designer system to be tailored to the needs of each individual project. Multiple Pharos Designer Controllers can be used together with up to 200 Remote Devices and will synchronise automatically.
