Distributor for Fema Electronica

Sunday, June 20, 2021

Ocean Controls is pleased to announce we have become a distributor for Fema Electronica. Based in Barcelona Spain, Fema has been in operation for over 50 years which is a bit of a rarity in the industrial controls and instrumentation field. In those 50 years, they have helped all kinds of machine builders with their instruments, with standard and customized solutions. They have innovated tirelessly, always striving to provide more reliable and accurate electronic equipment.

With a wide catalog of instrumentation for panel meters, signal converters, and large displays, FEMA is your trusted partner for your industry instrumentation

Large 4 or 6 Digit LED Displays.

The Series B offers a wide range of large format meters, for all type of industrial applications. Its differential feature is the large digit size implemented, with available versions with 60 mm digit height and reading up to 25 meters, and versions with 100 mm digit height and reading up to 50 meters. These instruments can perform control functions, as they can mount relay or transistor outputs, SSR controls, analog retransmission signals, and communications in Modbus RTU, RS-485 or RS-232 ASCII protocols. All circuits are isolated for better performance and protection.

The New I4E Universal Signal Converter

The new I4E, signal converters for electrical signals, are the first of a series of converters with advanced features. A TOP RANGE, for the most demanding applications. The new I4E 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.

  • Built in 4 digit display
  • Built in keypad configuration
  • Universal power supply 18 to 265 Vac/dc
  • Isolation 3KV input/output/power
  • Force’ functions temporarily forces the signal output to the minimum or maximum
  • ‘SOS’ mode manually set the output to a fixed value


M60-LC Load Cell Indicator (1 to 8 Load Cells)

Fema Electronica's M60-LC digital panel meter, with 96 x 48 mm (1/8 DIN) size and 6 digits with 14 mm digit height, for load cell signals. Able to connect to load cells of 1mV/V, 2mV/V and 3 mV/V, and signal ranges up to 100mV. Provides excitation voltage configurable to +5 Vdc or +10 Vdc (max. 140mA) to power up to 8 standard 350 Ohms cells. Scalable reading from 999999 to -199999 with configurable decimal point. 

Tare function, with configurable controls, and ‘auto-tare’ function for automatic tare correction when weight is removed from the cell. Three working modes with different acquisition speeds and noise rejection to 50 and 60 Hz. Output and control options with 1, 2 and 3 relays, isolated analog outputs, Modbus RTU communications, transistor outputs, SSR control outputs, RS-485 ASCII and RS-232. 

Special options up to 4 and 6 relays. Independent alarms configurable as maximum or minimum, with activation at setpoint or when reading is stable, with 1 or 2 setpoints per alarm, hysteresis, independent activation and deactivation delays, configurable inverted activation of the relay and configurable locked alarms
