Electrical Operating Conditions
Electrical Operating Conditions
Transients
The Digital IO module described in this manual is intended for low voltage
applications only and should not be connected to circuits that may generate or
conduct large transient voltages.
High Energy Sources
These modules are designed to handle inputs up to their rated currents or their
rated powers, whichever is less. Under certain fault conditions, high energy
sources could provide substantially more current or power than a module can
handle. It is important to provide external current limiting, such as fuses, if the
module inputs are connected to high energy sources.
Electrical Operating Conditions
This module is designed to operate in a temperature range of 0
°
C to +55
°
C with
non-condensing humidity. The maximum humidity is 95% at 40
°
C. Do not use in
locations where conductive dust or electrolytic salt dust may be present.
These modules should be operated in an indoor environment where temperature
and humidity are controlled. Condensation can pose a potential shock hazard.
Condensation can occur when the modules are moved from a cold to a warm
environment, or if the temperature and/or humidity of the environment changes
quickly.
Refer to the data sheet for maximum voltage, current, and power dissipation
ratings for each module. For the latest specifications, check the Keysight web
site at:

.
To avoid electric shock, turn off the chassis and disconnect
or de-energize all field wiring to the modules before
installing or removing any module or chassis slot cover.
Not for connection to mains. Do not connect any of the
module’s I/O pins directly to a mains power outlet.
Install current limiting devices between high energy sources and
the module inputs.
