The Brodie Model 200 Frequency-to-Analog Converter accepts a frequency input signal (TTL) compatible) and converts this input frequency to a linear Analog current output of 4-20 mAdc capable of driving standard process instrumentation.
The standard model has an integral 12 Vdc, 120 mA power supply to power accessory equipment.
The basic converter is completely solid state in design utilizing plug-in circuit boards and is packaged in a NEMA 1 enclosure.
The instrument is available with an optional NEMA 4 weatherproof enclosure.
In addition, the converter is available with a locally mounted 3-1/2 digit liquid crystal display enclosed with the converter in the NEMA 4 enclosure.
