Fema I3D accepts process signals in 4/20 mA and 0/10 Vdc, provides excitation voltage if needed. Dual output, with output 1 fixed to 4/20 mA, and output 2 configurable to 4/20 mA or 0/10 Vdc. Isolated 4 ways between power, input signal, output 1 and output 2.  We have a service to configure the I3D for you if you require it.

The I3P Signal Isolator accepts process signals (mA and Vdc), thermocouples (K, J, N, E, T, R, S, B), resistive temperature probes (Pt100, Pt500, Pt1000, Ni100, Ni1000, PTC and NTC), resistances and potentiometers. Easy configuration with configuration codes. We have a service to configure the I3P for you if you require it.

The new I4E signal converters from Fema can be configured to measure voltage signals (AC and DC) with ranges from 0 / 50mV up to 0 / 600V, current signals (AC and DC) from 0 / 5mA up to 0 / 5A, and frequencies from power lines (up to 100Hz). The output is a standard process signal configurable to 4 / 20mA or 0 / 10Vdc and has 4 Digit display. We have a service to configure the I4E for you if you require it.

Fema I4L is an isolated signal converter for load cell signals and millivolts. Provides +5 Vdc excitation voltage to power the load cell, and ‘sense’ function to compensate for excitation voltage variations. Accepts direct connection of 1, 2, 3 or up to 4 load cells (typical 350 Ohms load cells). We have a service to configure the I4L for you if you require it.

Fema I4P is an Isolated signal converter for process, temperatures, resistances and potentiometers. Output signal in 4/20mA and 0/10Vdc. Isolated 3 ways.  We have a service to configure the I4L for you if you require it.

Current loop isolator for 4/20mA and 0/50mA current loop signals, . It is designed for industrial OEM applications. The CCT-100 instrument does not need any type of configuration, and is powered from the input signal loop.
