CW-322

20 FOLD SIGNAL RELAY INTERFACES

We have expanded our CW-300 series for test bench technology with the CW-322, a module designed to control up to 20 signal relays via CAN bus. This module not only supports targeted actuation of a single relay, but also synchronized control of several relay channels.

The open design of the top-hat rail housing (45 mm to DIN) offers the user a fast, simple and at the same time cost-effective solution to automate switching signals, no matter if for every-day tasks in automation technology or on test benches.

The hole matrix integrated in the CW-322 makes it possible to add additional components to influence a relay channel or several signal paths, e.g. passive filter levels or the targeted merging or mixing of different signals.

In conjunction with the bus technology modules CW-101 and CW-102 it is possible to transfer measurement data via USB or Ethernet to a PC on the one hand, and to alter the configuration of the module on the other. A software API written in C/C++ and C# facilitates incorporating the module in proprietary programs.

PERFORMANCE CHARACTERISTICS

  • Up to 20 channels with signal relays
  • Control via CAN bus
  • Selective control of a single channel or simultaneous control of several channels possible
  • Hole matrix for own switching components (filter levels, etc.)
  • Quick and easy to install, suitable for top-hat rail (45 mm to DIN)
  • Easy to extend and scale channels
