Supply
961/962EN-4006 Current Draw
15V
103mA Typical, 113mA Maximum
18V
86mA Typical, 95mA Maximum
24V
67mA Typical, 74mA Maximum

CAUTION:
Risk of Electric Shock – More than one disconnect switch may
be required to de-energize equipment before servicing.
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):
Unit has demonstrated
measurement shift less than
±
0.25% of input span with interference
from switching solenoids, commutator motors, and drill motors.
Emissions Per European Norm EN50081-1:
Radiated Frequency Emissions:
30 to 1000MHz per EN55022 Class A
WARNING:
This is a Class A product. In a domestic environment, this
product may cause radio interference in which the user may be
required to take adequate measures.
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.
Conducted RF Immunity (CRFI):
10V rms, 150KHz to 80MHz, per
EN61000-4-6.
Surge Immunity:
0.5KV per EN61000-4-5.
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.
CAUTION:
Risk of Electric
Shock
– More than one
disconnect switch may be
required to de-energize the
equipment before servicing.
These limits represent the
minimum requirements of the
standard, but product has
typically been tested to comply
with higher standards in some
cases.
