Expansion modules for greater versatility

The wireless system is primarily used to communicate with remote devices in widely distributed systems. One unique feature is I/O mapping that allows signals to be distributed within the system easily and without software. Here, input signals receive I/O addresses by means of thumb wheels, with these addresses being mapped to corresponding output modules.

The wireless system has been upgraded with high-speed digital input and output modules that complement the existing wide-range inputs and relay outputs. The RAD-DI8-IFS input module processes eight digital input signals or two impulse signals between 0 and 100 Hz. The impulse inputs count events, for example, as a means of measuring the flow rate. The 32-bit counters can be read out directly via a Modbus RTU controller. The corresponding RAD-DO8-IFS digital output module processes eight digital signals that are triggered via transistor outputs.
