SPECIFICATIONS

DISPLAY:

3 1/2 digit LED, 1/2" high digits

MEASURING RANGES:

D.O.: 0-20.00 ppm and 0-100% saturation, switch

selectable
Temperature: 0-40°C (32 to 104°F)

POWER REQUIREMENTS:
98-132 Vac, 50/60 Hz (less than 10 VA)

Optional: 196-264 Vac, 50/60 Hz

AMBIENT CONDITIONS:

-30 to 50°C (-22 to 122°F)

0 to 90% R.H. non-condensing

ANALOG OUTPUTS:

Non-isolated 0-1 mA, 100 ohms maximum load
Non-isolated 0-5 Vdc, 1000 ohms minimum load

Isolated 4-20 mA, 800 ohms maximum load

The isolated output is isolated from the input, ground
line power and all other outputs

Range Expand: The 4-20 mA analog output can be

made to represent any segment of the measuring
scale. Minimum segment is 10% of full scale.

Output Hold: The analog outputs are automatically
placed on hold during calibration or other setup
operations.

Temperature Output: The 0-5 Vdc output can be
programmed to follow either the process temperature
or dissolved oxygen.

TEMPERATURE COMPENSATION:

Automatic 0 to 100°C (32 to 212°F)

ALTITUDE COMPENSATION:

Automatic 0 to 40°C (32 to 104°F)

DIAGNOSTICS:

When system erros is indicated, call STATUS to obtain
condition code. On-board simulated input to aid in
troubleshooting to obtain condition code.

MEMBRANE ALARM:

A relay activates if membrane is perforated.

TEST:
Display value and analog outputs can be set manually

to any value for testing and diagnostic purposes. This
feature allows the outputs to be tested independently
of process value.














SAFETY & SECURITY:

Non-volatile memory (EEPROM)
Passcode protected if selected

Watch-dog timer monitors microprocessor

Instrument automatically returns to on-line operation if

accidentally left in menu mode
(This feature may be held disabled if desired)

ACCURACY: % Saturation:

± 1%

Ppm:

± 0.1

Temp:

± 0.2°C

STABILITY: 0.1% of span per 24 hrs., non-cumulative

RESOLUTION: % Saturation:

0.1

Ppm:

0.01

Temp:

0.1°C


REPEATABILITY: 0.1% of span or better

RESPONSE TIME: 20 seconds to 90% of value upon
step change at 20°C

ENCLOSURE: NEMA 4X fibreglass reinforced polyester

enclosure with four 1/2” conduit holes and mounting

feet for surface mount

MOUNTING CONFIGURATIONS:

Standard is surface mount

Optional panel mount hardware. Part No. 35-68
Optional pipe mount hardware. Part No. 35-69

NET WEIGHT: 3 1/2 lbs. (1.6 kg)


























MODEL 2200D-X-2-X ADDITIONAL

FEATURES

CONTROL RELAYS:

Two relays can be independently set for
operation in response to rising or falling
value and for fail-safe operation. Deadband
(hysteresis) independently adjustable.

Rating: 5A 115/230 Vac, 5A 30 Vdc. SPDT

ALARM RELAY:

High-Low with fixed deadband of 2% of full
scale. Normal or fail-safe operation.

Rating: 5A 115/230 Vac, 5A 30 Vdc. SPDT


RELAY INDICATORS:

Three LEDs indicate status or the three

relays
