About the Board
The board is a 36-point I/O board that communicates via a DeviceNet network.
This board has 16 digital inputs, 16 digital outputs, 2 analog inputs, and 2 analog outputs.
Inputs are 24V dc sourcing or sinking. Digital outputs are self-protected 24V dc sourcing
(1799-D16U16BAGL) or sinking (1799-D16U16VAGL). Analog outputs support both
current and voltage outputs.
ATTENTION
This equipment is intended for use in a Pollution Degree 2 industrial environment, in
overvoltage Category II applications (as defined in IEC publication 60664-1), at altitudes
up to 2000 m (6562 ft.) without derating.
This equipment is considered Group 1, Class A industrial equipment according to
IEC/CISPR Publication 11. Without appropriate precautions, there may be potential
difficulties ensuring electromagnetic compatibility in other environments due to
conducted as well as radiated disturbance.
This equipment is supplied as open type equipment. It must be mounted within an
enclosure that is suitably designed for those specific environmental conditions that will
be present and appropriately designed to prevent personal injury resulting from
accessibility to live parts. The interior of the enclosure must be accessible only by the use
of a tool. The enclosure must have suitable flame-retardant properties to prevent or
minimize the spread of flame, complying with a flame spread rating of 5VA, V2, V1, V0 (or
equivalent) if nonmetallic. Subsequent sections of this publication may contain additional
information regarding specific enclosure type ratings that are required to comply with
certain product safety certifications.
In addition to this publication, see:
• Industrial Automation Wiring and Grounding Guidelines, Allen-Bradley publication
1770-4.1, for additional installation requirements.
• NEMA Standards publication 250 and IEC publication 60529, as applicable, for
explanations of the degrees of protection provided by different types of enclosure.
