11-36V DC SELV (Safety Extra Low Voltage).
Observe proper polarity. Current draw may decrease up to 10% as the
baud rate is increased to 12MB (data below is at 9600 baud).

CAUTION:
Risk of Electric Shock
– More than one disconnect switch may
be required to de-energize equipment before servicing.
Power Supply Effect:
Volts:
Less than
0.001% of output span change per volt for rated
power supply variations.
60/120 Hz Ripple:
Less than 0.01% of output span per volt peak-to-
peak of power supply ripple.
Isolation:
Input channels (as a group), power, and network circuits are
isolated from each other for common-mode voltages up to 250VAC, or
354V DC off DC power ground, on a continuous basis (will withstand
1500VAC dielectric strength test for one minute without breakdown).
Complies with test requirements of ANSI/ISA-82.01-1988 for voltage
rating specified.
Installation Category:
Designed to operate in an Installation in a Pollution
Degree 2 environment with an installation category (over-voltage
category) II rating.
Electromagnetic Interference Immunity (EMI):
Measurement shift is less
than
0.25% of input span for interference from switching solenoids,
commutator motors, and drill motors.
Electromagnetic Compatibility (EMC) -
Minimum Immunity Per European Norm EN50082-1:
Electrostatic Discharge (ESD) Immunity:
4KV direct contact and 8KV
air-discharge to the enclosure port per EN61000-4-2.
Radiated Field Immunity (RFI):
10V/M, 80 to 1000MHz AM and
900MHz keyed carrier, per EN61000-4-3 and ENV50204.
Electrical Fast Transient Immunity (EFT):
2KV to power, and 1KV to
signal I/O per EN61000-4-4.
Enclosure and Physical
Environmental
CAUTION:
Do not exceed
36VDC peak, to avoid damage
to the module.
External Fuse:
Select a high
surge tolerant fuse rated for
1A or less to protect unit.
Note that input channels are
not isolated channel-to-
channel, except for small
common-mode variations less
than ±4V peak.
These limits represent the
minimum requirements of the
standard, but product has
typically been tested to comply
with higher standards in some
cases.
