The RB-IPE is a 1U rackmount unit designed to provide remote control of GPIO and analogue control voltages over an Ethernet network. Configured using a built-in web server, two units can control each other across an Ethernet network, or a single unit can be controlled via Ethernet commands and the web server interface. The unit can be used in any position where you need to remotely acquire GPO signals or remotely control equipment, for example controlling equipment at unmanned posts, outstations or transmitter sites.
Each unit has 16 x general purpose inputs on 8 x RJ45 connectors, consisting of 8 x isolated current sink inputs and 8 x pull to ground protected inputs; and 16 x general purpose outputs on 8 x RJ45 connectors using 8 x isolated relay change-over contacts and 8 x opto-isolated contacts. These rear panel RJ45 connectors have an LED for each GPIO which shows its state.
On another 8 x RJ45 connectors there are also 8 x 0 to 3.3V/5V/12V input signals and 8 output signals nominally at 0 to 3.3V output, with other output voltage configurations possible. The outputs can all be controlled from the inputs of another RB-IPE, or from Ethernet commands.
This allows any tallies and control signals, together with analogue potentiometer movements, to be sent across a network, e.g. for remote alarm points, to trigger failure alarms at a transmitter site and to control remote equipment.
When two units are connected together at different sites, if a general purpose input state changes at one site the unit sends the new state to the other site and the appropriate opto-isolator output changes on that unit. Similarly input voltage controls are monitored and the changing voltage is sent to the remote unit where an output voltage changes accordingly.
The signals can be routed and distributed such that a single input signal to a unit on one site can be routed to multiple outputs in a unit on another site and/or have the logic inverted and distributed to multiple outputs. Also, the state of the GPOs when the unit is powered on can be configured, allowing more reliable recovery of external connected equipment from a power-fail condition.
The analogue I/O control signals can be mapped to give different ranges between the incoming and outgoing signal, e.g. 0V to 5V input giving a 0V to 12V output, or a linear input mapped to a log scale output. Also, by programming threshold values, analogue input voltages can be mapped to GPO pins, e.g. for sending a signal to a GPO when a volume knob is turned too high.
