CAUTION & SAFETY INFORMATION
If the equipment is used in a manner not specified in this manual, the
protection provided by the equipment may be impaired.
The Installation category is one (1).
The output terminals of this product are for use with equipment (digital
meters, chart recorders, etc.) which have no accessible live parts. Such
equipment should comply with all the applicable safety requirements.
Do not operate the equipment in flammable or explosive environments.
The unit comes with two 4.6 m (15') shielded multi-conductor cables. The
sensor cable is a five conductor, 24 AWG stranded wire with a rating of 600
Vdc, 205°C (401°F) PTF insulation. The power/output cable is an eight
conductor 24 AWG stranded wire with rating of 300 Vdc, 105°C (221 °F)
PVC insulation.
Power must be disconnected before making any electrical connections.
The recommended power supply should be VD or UL approved. Rating: 8-
24 Vdc @ 100 mA minimum power with overload protection, current limited
to 500 mA.
The supply voltage to the transmitter should not exceed 24 VDC.
There is only one fuse in the OS550A. Disconnect power before replacing the
fuse. The fuse must be replaced with one of identical size and rating. Fuse
Specifications: 125 mA/250 Vac, Time-lag, 5 x 20 mm with UL and/or VD
Approvals such as Wickmann No. 19195-028.
All connections made to the thermometer should be made via a stranded
wire, shielded cable, 24 AWG (min), such as OM GA ngineering's Model
TX4 or TX8 series. Wiring requirements for this unit are Class II.
SAFETY WARNINGS AND IEC SYMBOLS
This device is marked with international safety and hazardous symbols in
accordance with I C1010. It is important to read and follow all the
precautions and instructions in this manual before operating or
commissioning this device as it contains important information relating to
safety and MC. Failure to follow all the safety precautions may result in
injury and/or damage to your equipment.

General Description 1
1.1 Introduction
The OS550A Series Industrial Infrared (IR) Thermometers provide
non-contact temperature measurement up to 4500°F (2482°C). They
offer effective solutions for many non-contact temperature
applications, including the following:
•Predictive aintenance: Tracking temperature shifts which
indicate pending failure in solenoid valves.
•Energy Auditing: Locating wall insulation voids to reduce
building heating costs.
•Food Processing: Taking accurate temperature readings
without direct contact with the food or packaging material.
•Annealing Processing: Monitoring surface temperatures of
metals while it is inside an oven by seeing through glass
window.
The IR thermometer provides a custom backlit dual digital LCD that
displays both current and minimum, maximum, average or
differential temperatures. This versatile instrument provides:
• Measurable target distances from 5 inches (12.7 cm) to
approximately 200 feet (61 m)
• missivity adjustable from 0.1 to 1.00 in 0.01 steps provides
ease of use when measuring a variety of surfaces.
• Continuous temperature measurement up to 10 times per
second.
• Audible and visual alarms. The high and low alarm points
are set via the keypad.
• Analog output, 1 mV/degree,4-20mA or 0-5VDC
which allows interfacing with data acquisition equipment
(including chart recorders, data loggers and computers)
• Two way RS232 serial communication to a PC. This allows
downloading data for further analysis (OS552A, OS553A
and OS554A, OS555A).
• Ambient target temperature compensation. This provides
more accuracy for measuring low emissivity targets.
• Record up to 800 temperature data points either continuos or
on demand. Review the recorded data on the thermometer
LCD, as well as downloading the data to a PC (OS553A and
OS554A, OS555A).
• Backlit display useful in low ambient light conditions
• Laser Sighting is optional.
• High and Low Alarm outputs to drive external Mechanical
Relays

1.2 Thermometer Features
The thermometer is easy to use:
• Temperature readings are switchable from °F to °C via the
keypad.
• Parameters, such as target material emissivity and alarm
setpoints, can be set and remain in non-volatile memory
until reset.
This instrument has a rugged and functional design, including:
• Sealed keypad display.

2.1 Installation
2.1.1 Sensor Head Installation
The OS550A’s sensor head is made of black anodized aluminum. Both ends
of the sensor head come with a 11⁄2- 20 standard threaded mounting
connection. The sensor head is connected to the main display electronics via
a 15'shielded cable and environmentally sealed twist lock connector.
Mounting accessories are available. See page 2-2 for sensor head
dimensions.
If the sensor head is used in an environment where the
ambient temperature is above 122°F (50°C), the water
cool jacket accessory (OS550-WC) must be used to
maintain accuracy and prevent damage to the sensor
head. See Chapter 3.1.
2.1.2 OS550A Series NEMA Plastic Housing Installation
The OS550A Series’ main display and electronic’s housing is
environmentally sealed and weather tight. Mounting ears are provided
making mounting easy. Mount the main electronics assembly in a location
that you can easily access to view the LCD and make program changes to
the unit. See case and mounting plate dimensions on page 2-3.
2.1.2A OS550AM Series NEMA Aluminum Housing
The OS550AM Series is available in a N MA Aluminum Housing as an
option. Refer to figure 2-2A for case and mounting hole dimensions.
2.1.3 OS550A-BB OEM Style Display Installation
The main display and electronics assembly is provided with an aluminum
mounting plate making installation of this O M style system economical
and easy to customize. Assembly should be mounted in a location that is
free of dirt, grease, oils, and other liquids. See mounting dimension
on page 2-5.
