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 are individually isolated relays (48V, 0.25A). 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.
Timing is everything. Whatever the stimulus, Pharos Trigger can handle it. You can control your lighting with responsive, reactive programming. Pharos Trigger is a rules engine that uses conditional logic and a broad range of interfaces and protocols. Send and receive any command, to and from any system. Conditional logic is supported, along with a powerful built-in scripting language for unlimited flexibility.
Up to 200 Remote Devices can be combined with one or more Pharos Controllers on the same network to build the ideal system for your installation. Each Remote Device is easily addressed using a convenient thumb wheel. Whether one Controller or many, it’s all easily programmed using our Designer software.
Each input is individually configurable in one of three modes. As a Contact Closure an external volt-free switch may be connected across the input. As a Digital Input an external voltage source (up to 24V) can be connected across the input and thresholds for ‘high’ and ‘low’ triggering can be set. As an Analog Input a variable external voltage can be measured within a configurable range.
Every RIO has a multi-protocol serial port, whose protocol (RS232 or RS485), data rate and format settings (baud, parity, stop bits, etc.) are configurable in software. The port can also be configured to output up to 96 channels of DMX512.
As a Power-over-Ethernet (PoE) device, the RIO can be placed at any remote location and only needs a single Cat5 cable that provides both power and data.
Our outputs use solid-state relays to ensure silent operation and long-term reliability. They are designed for low voltage, low current switching (48V, 0.25A) and are also fully isolated. Where necessary they enable higher currents to be controlled from Pharos by integration with commonly available third-party contactors.
Made for permanent installation, with installer-friendly 0.200” (5.08mm) plug-in rising clamp terminals, a rugged, compact enclosure, and easy DIN rail mounting.
Programmed and configured using the free Pharos Designer 2 software – available for Windows or Mac OS X – with upload over Ethernet or USB.
Works with any Pharos Controller and links to it using standard protocols over an Ethernet network.
Microprocessor-based system supports firmware updates via the network from Designer software or the web interface.
