Knick VariTrans P 27000 universal isolators are designed for galvanic isolation and conversion of input signals from 0 ... ± 200 V to output signals from ±0 ... 10 V or ± 0 ... 20 mA. They feature linear signal transmission, broad-range mains adapter for powering with voltages from 20 to 253 V AC/DC, and pluggable screw clamp terminals for easy connection. These isolators are commonly used in industrial settings for electrical isolation, signal conversion, and data transmission in various applications such as process control, automation, and measurement systems.

Universal Isolators

TA-251.101-KNE01 20111128

1. Safety Information

The warning symbol on the device (exclamation point in triangle) means: Observe instructions!

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!

Caution!

Be sure to take protective measures against electrostatic discharge

(ESD) when handling the devices!

Caution!

The VariTrans® P 27000 universal isolators must be installed only by qualified and specially trained personnel authorized by the operating company.

Do not connect the device to power supply before it is professionally installed.

Do not change the measuring range during operation. Observe the national codes and regulations during installation and selection of cables and lines.

Equipment shall be provided with a means for disconnecting it from each operating energy supply source. The disconnecting means shall disconnect all current-carrying conductors. (It must be easily accessible and clearly identifiable by the operator.)

Mains supply must be protected by a fuse of 20 A max.

Warning! EXPLOSION HAZARD

Do not connect/disconnect equipment unless power has been removed or the area is known to be non-hazardous.

Warning! EXPLOSION HAZARD

Substitution of components may impair suitability for Class I,

Division 2.

Conditions for safe use (Haz. Loc.)

For the use in hazardous locations, this equipment is to be installed into suitable enclosure, providing a degree of protection not less than IP 54.

Devices containing user accessible switches and/or potentiometers: the device must be installed into an end-use enclosure with tool removable cover.

2. Intended Use

The special models P 27000-S008 universal isolators are used for galvanic isolation and conversion of input signals from 0 ... ± 200 V to output signals from ±0 ... 10 V or ± 0 ... 20 mA. The calibrated output signal range is selected via

DIP switches. Signal transmission is linear. By means of the broad-range mains adapter, the units can be powered by voltages from 20 to 253 V AC/DC.

Connection is made using pluggable screw clamp terminals.

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.

3. Configuration

3.1 Tools

A screwdriver with a width of 2.5 mm is required to open and adjust the unit and to connect the wires to the screw clamp terminals.

4

3.2 Opening the unit

Disengage the top part of the housing on both sides using the screwdriver.

Pull out the top part of the housing and the electronics section until they lock.

3.3 Settings

Adjust the output range using DIP switches

S1, S2 and S3 as shown in the tables or on the rating plate.
