TIY
Specifications
Performance Output Accuracy:
±0.05% of span
(maximum input-to-output
error is the sum of the
input, output and
Reference Junction Com-
pensation accuracy values.
See Table 1 for details).
Ripple:
Less than 10mV
peak-to-peak, maximum
(up to frequencies of
120Hz) measured across
a 250 ohm load resistor
Burnout Protection:
Upscale drive is the
standard factory
configuration; downscale
drive can be configured
via a solderless jumper
Operating Limits:
No
damage up to ±42V on
input and ±60V on output
Output Protection:
Transient protection and
reverse polarity protection
Output Current Limiting:
125% of span, typical;
130% of span, maximum
Load Capability:
(Vp–12V)/0.024A = ohm
Common Mode Rejection:
At least 120dB at
50Hz/60Hz
Isolation:
500Vrms
galvanic
isolation between input and
output terminals
RFI/EMI protection:
When
tested according to SAMA
Standard PMC 33.1,
protection rates:
DIN and HP/FL Housings:
10V/m–ABC
2
0.1% of
maximum span (for 30V/m
protection on DIN housing,
see the -RF option)
2LG and 2LS (HP housing
in explosion-proof
enclosure): 30V/m–ABC
2
0.025% of maximum span
Operation:
-40°C to +82°C
(-40°F to +180°F)
Momentary, recoverable
dimming of display may
occur
at low temperatures
Effect (except reference
junction compensation):
±0.01% of maximum
span/°C
Reference Junction
Compensation Effect:
Reference junction
compensation effect,
±0.75°C/50°C change in
ambient temperature

Ambient
Temperature
Zero and Span:
Membrane push
buttons. Span
changes within an
input range (see
Range Codes in
Table 1) are made
with membrane push
buttons; changing
Range is done by
changing the positions
of solderless jumpers
Type:
4-digit LCD
indicates input value
in °C, °F or millivolts
(jumper-selectable);
also indicates zero
and full-scale values,
problem codes and
high or low table limit
warnings
Display Accuracy:
±0.1% of maximum
span for range code,
±1 count
