2.0 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
