1. Safety Information
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.
Caution!
Be sure to take protective measures against electrostatic discharge
(ESD) when handling the devices!
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!

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.
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.
Conditions for safe use (Haz. Loc.)

2. Intended Use
The special models P 27000-S007 universal isolators are used for galvanic
isolation and conversion of input signals from 0 ... ±10 V to output signals from
0 ... ±20 mA. 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.

5
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 table below.
