3.1 I/O Options

ControlWave GFC comes with the following standard I/O:

 2 Pulse Counter Inputs with a 1 second scan rate (can be configured

as discrete inputs (DI))

 The 14 MHz CPU and the 33MHz CPU with Ethernet also includes

a Resistance Temperature Device (RTD) probe.

In addition, three different versions of the optional process I/O board are

available:
