Product Specification

Caution!

Be sure to take protective measures against electrostatic discharge (ESD) when handling the devices!

Note for installation

Installation must be performed by qualified personnel.

Warning! Protection against electric shock

For applications with high working voltages, take measures to prevent accidental contact and make sure that there is sufficient distance or insulation between adjacent devices.

Intended use

The Series BasicLine 54x standard-signal isolators are used for galvanic isolation of 0(4) to 20mA standard signals. The measured signal is transmitted 1:1. Power supply is not required.

Warning against misuse

Do not operate the device outside the conditions specified by the manufacturer, as this might result in hazards to operators or malfunction of the equipment.

Caution

The system installer is responsible for the safety of the system in which the device is integrated.

Method of operation

BasicLine 54x standard-signal isolators draw the power required for their isolation task from the input signal (“passive isolators”).

A current signal I = 20 mA and a voltage drop of 1.7 V (typ.) across the passive isolator result in a load-dependent input voltage of Vin = 1.7 V + 20 mA * RL (load)
