Fema I4F isolated signal converter for frequency, impulses, RPM speed and flow signals
Fema I4F is an Isolated signal converter for frequency, impulses, RPM speed, and flow signals. Output signal in 4/20mA and 0/10Vdc. Isolated 3 ways.
Configurable to work with NPN, PNP, Pick-up, Namur, mechanical contact, reed contact, and other sensors. Dedicated input to measure frequency from AC voltage up to 600 Vac.
Accepts a wide range of frequency ranges, from 1 Hertz up to 1 MHertz, with a minimum workable signal of 100 milliHertz and resolution of 1 milliHertz.
We have a service to configure the I4F for you if you require it.

Accepts a wide range of frequency ranges, from 1 Hertz up to 1 MHertz, with a minimum workable signal of 100 milliHertz and resolution of 1 milliHertz.
Output signal configurable for 4/20 mA (active and passive) and 0/10 Vdc. Universal power supply from 18 to 265 Vac/dc. 3-way isolation between input, output, and power circuits.
Customizable input and output signal ranges. Configuration through front push-button keypad and front display. Configurable information messages (tare value, mV at terminals, input signal value, output signal value, configured label, signal percentage, process value, excitation voltage value, and excitation current value). Manual "force" functions to generate low and high output signals, to validate remote instrumentation during installation. "Tare" function. "Password" function to block unauthorized access to the configuration menu. "SOS" mode to help with critical maintenance and repairs without affecting the manufacturing process.
Designed for industrial use, with potential integration into a wide range of applications. Optional customization.
