Description

20 Hz

The API 7500 G accepts a DC voltage or current input and

provides an optically isolated frequency output that is directly

proportional to the input. Common applications include pulse

counting or totalizing of DC process signals from devices such

as flow transmitters, analog signal transmission over long

distances, or analog inputs into PLCs. The full 3-way (input,

output, power) isolation makes this module useful for ground

sink

loop elimination, common mode signal rejection, and noise

depending on load

p-p

pickup reduction.

A low frequency cutout potentiometer can be adjusted to dis-

able the output when the input falls below a pre-determined

level. The API 7500 G can be field-configured via external

rotary and slide switches. Common ranges are on the module

label, however, virtually unlimited combinations are possible.

The API 7500 G has an open drain MOSFET (open collector)

output which requires a user supplied external power supply

and pull-up resistor allowing the module to be interfaced with

a wide variety of devices. For a TTL powered output, order the

M02 option.

Sink/Source Versatility

For maximum versatility the input can be selectively wired for

sinking (unpowered) or sourcing (powered) milliamp output.

The 18 VDC loop excitation supply can be used to power a

milliamp current loop if required. The input can also be wired

for an externally powered loop.

LoopTracker

API exclusive features include two LoopTracker LEDs (green for

input, red for output) that vary in intensity with changes in the

process input and output signals. These provide a quick visual

picture of your process loop at all times and can greatly aid in

saving time during initial startup and/or troubleshooting.

Output Test

An API exclusive feature includes the test button to provide a

fixed output (independent of the input) when held depressed.

The test output level is potentiometer adjustable from 0 to

100% of the output span.

The output test button greatly aids in saving time during initial

startup and/or troubleshooting.
