1.0 INTRODUCTION
1.1 Description
The INFINITY series is a complete line of process indicators/controllers, offering exceptional performance.
The DFI INFINITY strain gauge meter is front panel configurable to accept 0-20 and 4-20 mA dc current inputs,
unipolar and bipolar DC voltage inputs and potentiometer inputs. The DFI INFINITY meter will accept inputs from
most of the process sensors in use today such as transmitters, pressure transducers, and potentiometers.
Configuring the INFS is accomplished through the 5 front panel buttons. If the optional RS-232 or RS-485
communications are installed, the user may remotely set the display parameters.
Options for the INFINITY include analog and BCD outputs, relay outputs, and RS-232 or RS-485 communications.
