Digital Isolators

G Instruments designs and manufactures a range of isolators, isolated splitters and converters with high functionality and reliability.


Pulse Isolator
DIN rail pulse isolators

GPi11 is a DIN rail mount pulse isolator with a passive input and passive output. Both input and output connect with 2 wires only. The output has no polarity and can equally switch DC or AC current.



Isolated Pulse Splitter
DIN rail pulse splitters

GPi12 is a DIN rail mount isolated pulse splitter with a passive input and 2 passive outputs. The input and both outputs connect with 2 wires only. The outputs have no polarity and can equally switch DC or AC current.



Isolated Frequency to Analog Converter
Isolated Frequency to analog converter

GPi13 is a DIN rail mount isolated frequency to analog signal converter. The input can power the sensor and accepts npn / pnp open drain / collectors, reed switches, dry contacts, waves, logical signals and others. The input frequency is 0 to 30 000 Hz in 8 ranges. The output can be configured to active / passive, 0-20 mA, 4-20 mA, 0-5 V, 0-10 V, 1-5 V, 2-10 V. GPi13 needs 24 VDC (21.6 - 26.4 V) for power. No programming required, the device can be configured on the field in seconds by setting a couple of DIP switches only. The power is isolated from the input and from the output. The input is also isolated from the output.



Pulse Converter / Linearizer
Pulse linearizer

GPC5K has a 30 point calibration / linearization table and an isolated output which frequency is related to the input frequency through the 30 point table. This way GPC5K can be used, for an instance to linearize and isolate flow meters or other devices with a pulse output. The output can be 5V square wave or open drain.
