RIO
The RIO may be configured using Designer to specify what the 'high' and 'low' threshold
voltages are. This facility can be used to provide 'Schmitt trigger' action.
Analog input: An external voltage source (such as a 0-10V analog signal) may be
connected between the input pin and the signal ground pin.
In this mode, the input pin is internally pulled down to 0V via a 2Mohm resistor and the
maximum input voltage supported is 24V.
The RIO may be configured using Designer to specify what the input voltage range is.
Voltages inside this range are reported as 0% to 100%.
In all modes, the maximum rated input voltage is 24V. The inputs should never be driven
with a higher voltage nor negative voltage or damage may occur.
• Relay Outputs (RIO 08 and RIO 44 only)
The RIO features 8 (RIO 08) or 4 (RIO 44) relay outputs on two (RIO 08) or one (RIO 44)
8 way connectors.
The RIO relays are rated at 48V, 0.25A. This comparatively low rating is due to the use of
solid-state relays to ensure silent operation and long-term reliability.
All relay outputs are fully isolated from each other and all other ports.
• RS232/RS485/DMX Serial Port (RIO 80, RIO 44 and RIO 08 only)
The serial port's protocol (RS232 or RS485), data rate and format settings (baud, parity,
stop bits, etc.) are configured using Designer. The port can additionally be configured to
output 96 channels of DMX512 control data (RDM is not supported).
In RS232 mode, the port operates in full duplex with the following pinout:
Receive
Transmit
Signal ground
In RS485 & DMX modes, the port operates in half duplex with the following pinout:
Data +
Data -
Signal ground
• MIDI Input and Output (RIO-A only)
The MIDI input and output connectors are standard 5 pin DIN connections. They may be
connected directly to any standard MIDI device.
