To expand the number of controlled parameters, RDF has a series of plug-in modules housed in dedicated rack units. Inputs and Outputs
number can be expanded to manage an incredible amount of data:

  • Up to 256 analog inputs (8, 10, 12 or 16 bit resolution)
  • Up to 248 digital inputs (contact inputs on-off)
  • Up to 256 relays (digital output)
  • Up to 32 x 10bit resolution analog outputs.

They are configurable, both locally and remotely, and are programmable to generate alarms or run simple routines, called macros.
Furthermore, the I/O state can be read, both on site and remotely, at any time. There are two versions of dedicated rack mounts to host expansion modules:

  • PW-RACK, featuring an independent embedded power supply
  • BS-RACK, that uses power distributed via RS485

The ANT153 is meant to switch up to 4 low power RF signals to a single output.
Useful to collect RF samples from transmitters and route them to analysis equipment. The board contains switching components, a series attenuator, a microcontroller and a set of dip switches for fixed attenuation settings as described graphically in the following figure.
It can be controlled manually thru dip switch settings, or remotely via RS485. The board is intended to be used inserted in ANT Group’s modular rack system.
