Analog Inputs

Analog inputs can measure and store analog information such as electrical signals from transducers; transducers derive the electrical signals from flow rates, temperatures, pressures, rotations, and fluid levels. They are controlled by Analog Input modules.

Analog inputs require the installation of an optional circuit board inside the meter. The I/O card provides four analog inputs. By default, four Analog Input modules (labeled AI1 to AI4) are already created for this purpose. Configure the settings of the controlling module to match your requirements. The settings in these modules are as follows:

Setup	Available Settings	Creation	Description
Registers	Available Settings	Default	Description
Registers		Default

Port	Not Used or	Not Used	The input hardware channel
Port	AI1 to AI4 inclusive	Not Used	The input hardware channel
	AI1 to AI4 inclusive

	-1 x 109 to 1 x 109		Defines what value appears in the
Full Scale	-1 x 109 to 1 x 109	1	ScaledValu output register when the highest
			possible value from the hardware is applied

Zero Scale	-1 x 109 to 1 x 109		Defines what value appears in the
Zero Scale		0	ScaledValu output register when the lowest
1		0	ScaledValu output register when the lowest
1			possible value from the hardware is applied
			possible value from the hardware is applied

1An arbitrary input value can be treated as the Zero Scale (i.e., a 4-20mA input is capable of generating a 0 to X output).

Analog Outputs

An ION meter’s analog outputs act as transducers. The meter measures power and energy, and then sends that information via the analog outputs to a remote terminal unit (RTU). The analog outputs issue industry standard 0 to 20 mA current signals. They are controlled by the Analog Output modules.

Analog inputs require the installation of an optional circuit board inside the meter. The I/O Card provides four analog outputs. By default, four Analog Output modules (labeled AO1 to AO4) are already created for this purpose. Configure the settings of the controlling module to match your requirements. The settings in these modules are as follows:

Setup	Available Settings	Creation	Description
Registers	Available Settings	Default	Description
