Fema I4L isolated signal converter for Load Cells
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.
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). Accepts 4 and 6 wire load cells. Accepts unipolar and bipolar ranges up to ±80 mV.
Output signal configurable for 4/20 mA (active or passive) and 0/10 Vdc. Universal power supply from 18 to 265 Vac/dc. 3 way isolation between input, output and power circuits. Plug-in screw terminal connections. Circuit isolation prevents ground loops and transient propagation, protecting remote equipment and signal integrity.
Two configuration modes: (1) easy and fast using predefined configuration codes, and (2) advanced configuration trough the ‘configuration menu’ to customize input and output signal ranges. Configuration through front push-button keypad and front display. ‘Tare’ function accessible from front key pad. Configurable display information (tare value, input signal value, output signal value, configured label, signal percentage, process value, excitation voltage and excitation current values). Manual ‘force’ functions to generate low and high output signals, to validate remote instrumentation during installation. ‘Password’ function to block non-authorized access to configuration menu. ‘SOS’ mode to help on critical maintenance and repairs without affecting the manufacturing process. Designed for industrial use, with potential integration into a wide range of applications, excellent quality and optional customization
