Red Lion Controls

The AIMI0202 passive isolator is used for the electrical isolation and processing of analog 0(4) to 20 mA standard current signals. The AIMI0202 provides electrical isolation between the control electronics and process I/O. In addition, interference signals above 75 Hz are effectively suppressed. Input and output circuit do not require separate auxiliary power.

AIMI 0 (4) to 20 mA Passive Loop Powered Isolator

The AIMI0202 obtains power from the input signal. The modules are snapped onto symmetrical DIN rails in accordance with EN 50022.

When using the AIMI0202, ensure the voltage supply is sufficient for handling both the voltage drop of the input and the output load voltage drop. The AIMI0202 input resistance will create around a 1.7 V drop.

The energy for the supply on the input side is taken from the analog input signal. Due to the dynamic input resistance, a power loss of approximately 1.7 V drops at the module input. The module's output is self-powered (active), which is also derived from the input signal.

Connect transducer to input (Terminals 1 & 2), observing polarity. A power supply may be required for loop powered transducers.

  • 0(4) to 20 mA Passive Loop Powered Isolator
  • Provides Input/Output Isolation

The following formula calculates the total voltage drop (input and output). Total voltage drop = (1.7 V + (20 mA * RLOAD)) Where:

  • 1.7 V = Input voltage drop
  • 20 mA * RLOAD = Output load voltage drop

NK Technologies Switches

Solid-State Contacts generally have a much lower capacity, making this sensor much more versatile than most selfpowered models. Available in a solid-core case only. AS1 Series are self-powered, SPST relay output currentoperated switches which trigger when the current level sensed through the aperture exceeds the minimum. The relay output contacts can switch up to 120 VAC or 30 VDC; this "universal" output makes them well

Datalogic Sensors

The Terminal Block Connection simplifies and speeds-up the installation procedure, whereas the heavy-duty plastic housing guarantees excellent resistance under harsh use conditions. The S300 PA series of advanced MAXI photoelectric sensors represents the most suitable solution for standard applications thanks to it's excellent cost/performance ratio. The new series offers a wide range of models and functions in order to
