GENERAL

HAZARD-

OUS

VOLTAGE

CAUTION

WARNING

To avoid the risk of electric shock and fire, the safety instructions
of this manual must be observed and the guidelines fol lowed. The
specifications must not be exceeded, and the device must only be
applied as described in the following.
Prior to the commissioning of the device, this manual must be
examined carefully.
Only qualified personnel (technicians) should install this device.
If the equipment is used in a manner not specified by the
manufacturer, the protection provided by the equipment may be
impaired.
Until the device is fixed, do not connect hazardous voltages to
the device.

Repair of the device must be done by OMEGA ENGINEERING
only.

WARNING

In applications where hazardous voltage is connected to in-/
outputs of the device, sufficient spacing or isolation from wires,
terminals and enclosure to surroundings (incl. neighbouring
devices), must be ensured to maintain protection against electric
shock.

Potential electrostatic charging hazard. To avoid the risk of
explosion due to electrostatic charging of the enclosure, do not
handle the units unless the area is known to be safe, or appropriate
safety measures are taken to avoid electrostatic discharge.

2

SYMBOL IDENTIFICATION

Triangle with an exclamation mark: Read the manual before installation

and commissioning of the device in order to avoid incidents that could lead
to personal injury or mechanical damage.

The CE mark proves the compliance of the device with the essential
requirements of the directives.

3

SAFETY INSTRUCTIONS

RECEIPT AND UNPACKING

Unpack the device without damaging it and check whether the device type
corresponds to the one ordered. The packing should always follow the device until
this has been permanently mounted.

ENVIRONMENT

Avoid direct sunlight, dust, high temperatures, mechanical vibrations and shock, as
well as rain and heavy moisture. If necessary, heating in excess of the stated limits
for ambient temperatures should be avoided by way of ventilation. All devices can be
used for Measurement / Overvoltage Category II and Pollution Degree 2. The module
is designed to be safe at least under an altitude up to 2 000 m.

MOUNTING

Only technicians who are familiar with the technical terms, warnings, and
in structions in the manual and who are able to follow these should connect the
device.
Should there be any doubt as to the correct handling of the device, please contact,

Mounting and connection of the device should comply with national legislation for
mounting of electric materials, i.e. wire cross section, protective fuse, and location.

Descriptions of input / output and supply connections are shown in this manual
and on the side label.

The device is provided with field wiring terminals and shall be supplied from a
Power Supply having double / reinforced insulation. A power switch should be
easily accessible and close to the device. The power switch shall be marked as the
disconnecting unit for the device.

DRSL Series must be mounted on a DIN rail according to EN 60715.

UL INSTALLATION

Use 60/75°C copper conductors only.

Wire size ...................................................................... AWG 26-12

UL file number .......................................................... E70366

The device is an Open Type Listed Process Control Equipment. To prevent injury
resulting from accessibility to live parts the equipment must be installed in an
enclosure.

OMEGA Engineering, Inc.

4

The power supply unit must comply with NEC Class 2, as described by the National
Electrical Code

®

(ANSI / NFPA 70).

5

CLEANING

When disconnected, the device may be cleaned with a cloth moistened with
distilled water.

6

FLEXIBLE SUPPLY

The units can be supplied with 24
VDC±30% via direct wiring and a loop
between the devices. This permits the
supply of up to 130 units.

Protective fuse: 2.5 A.

Protective fuse: 0.4 A.

Alternatively, the 24 V supply voltage can
be distributed via a power rail that receives
the voltage from another connected unit
(DRSL-DC1, DRSL-DC2, DRSL-DC3 DRSL­SP1, DRSL-SP2, or DRSL-U). In this way up
to 20 units can be supplied.

Fuse characteristics: The 2.5 A fuse must break after not more than 120 seconds
at 6.4 A.

The power connector unit DRSL-PCU
is a standalone supply unit which
supplies the power rail. With DRSL­PCU, up to 100 units can be supplied.

Protective fuse: 2.5 A.

INSTALLATION ON DIN RAIL

To avoid short circuit between the power rail connectors on the DRSL devices and

the screws holding the 7.5 mm DIN rail, the head of the screws shall be no more
than 3.5 mm high.

35 mm

> 24 mm

< 3,5 mm

SUPPLY OF POWER RAIL

It is possible to supply the power rail via the supply terminals.

The terminals can pass a current of max. 400 mA.

INSTALLATION ON POWER RAIL

Module stop
(DRSL-MOD-STOP)

All devices can be installed on a power rail (part number DRSL-PWR-RAIL).

Power supply units can be mounted on the power rail according to customer
requirements.

MARKING

The front cover of the DRSL series

has been designed with an
area for affixation of a click-on
marker. The area assigned to
the marker measures 5 x 7.5
mm. Markers from Weidmüller’s
MultiCard System, type MF
5/7.5, are suitable.

DIP-SWITCH PROGRAMMING

The devices DRSL-DC2, DRSL-DC3 and DRSL-SP2 can be configured via DIP-

switches. The DIP-switches are located on the side of the device and can be
adjusted with a small screwdriver or other implement.

Adjustment of DIP-switches.
Default factory settings are:

Input=0…20mA
