ANALOG SCALING MODULE

GT-ASM

PRODUCT DESCRIPTION

The GT-ASM analog scaling module is used for analog

signal conversion or re-scaling. It will accept one DC

voltage, current or resistance input signal and output a

non-isolated voltage or current signal. The output signal is

easily calibrated for various offsets and spans and can be

direct or reverse acting to provide signal inversion.

The GT-ASM also includes a regulated power output that

can be used to power a transducer or resistance input.

It features top-adjust trim-pots for offset, gain, input

attenuation and reverse-offset calibration. There is also an

LED power indicator.

The product comes with standard snap-track for easy

mounting or is also available mounted in a hinged ABS

enclosure.

APPLICATIONS

•

Resistance to voltage or current conversion

•

Voltage to voltage or current conversion

•

Current to voltage or current conversion

•

Voltage or current signal reversal
