Safety information –
Be sure to read and observe the following instructions!
The device has been manufactured using state of the art technology
and it complies with applicable safety regulations.
When operating the device, certain conditions may nevertheless lead
to danger for the operator or damage to the device.
CAUTION!
Commissioning must be carried out by trained experts.
Whenever it is likely that protection has been impaired, the device
shall be made inoperative and secured against unintended operation.
The protection is likely to be impaired if, for example:
• the device shows visible damage
• the device fails to perform the intended measurements
• after prolonged storage at temperatures above 70°C
• after severe transport stresses
Before recommissioning the device, a professional routine test in
accordance with EN 61010-1 must be performed. This test should be
carried out at the manufacturer's factory.
CAUTION!
Before commissioning, make sure that the transmitter may be
connected with the other equipment.

Intended Use
Stratos Eco 2405 Oxy is used for dissolved oxygen and temperature
measurement in biotechnology, pharmaceutical industry, as well as in
the eld of environment, food processing, and sewage treatment.
The sturdy molded enclosure can be xed into a control panel or
mounted on a wall or at a post.
The protective hood provides additional protection against direct
weather exposure and mechanical damage.
The device has been designed for application with amperometric
sensors, e.g. Knick SE 703 / SE 706. It provides two current outputs
(for transmission of measured value and temperature, for example),
two contacts, and a universal power supply 24...230VAC/DC,
AC: 45 ... 65 Hz.

Installation Instructions
CAUTION!
• Installation of the Stratos must be carried out by trained experts in
accordance with this user manual and as per applicable local and
national codes.
• Be sure to observe the technical specications and input ratings
during installation.
• Be sure not to notch the conductor when stripping the insulation.
• Before connecting the device to the power supply, make sure that
its voltage lies within the range 20.5 to 253V AC/DC.
• All parameters must be set by a system administrator prior to
commissioning.
The terminals are suitable for single wires and exible leads up to
2.5mm2(AWG 14).

Protective Wiring of Relay Outputs
Protective Wiring of Relay Contacts
Relay contacts are subjected to electrical erosion. Especially with
inductive and capacitive loads, the service life of the contacts will be
reduced. For suppression of sparks and arcing, components such as RC
combinations, nonlinear resistors, series resistors and diodes should
be used.

2 RC combination, e.g. RIFA PMR 209
Typical RC combinations for 230 V AC:
Capacitor 0.1 µF / 630 V Resistor 100 ohms / 1 W

Protective Wiring of Relay Outputs
Typical Protective Wiring Measures
A: DC application with inductive load
B: AC/DC applications with capacitive load
C: Connection of incandescent lamps
A1 Inductive load
A2 Free-wheeling diode, e.g. 1N4007 (Observe polarity)
A3 Contact
B1 Capacitive load
B2 Resistor, e.g. 8 Ω / 1 W at 24 V / 0.3 A
B3 Contact
C1 Incandescent lamp, max 60 W / 230 V, 30 W / 115 V
C3 Contact
WARNING!
Make sure that the maximum ratings of the relay contacts are not
exceeded even during switching!
