Product Details
The AB 1756-OB8 is a ControlLogix DC output module. It has 8
outputs available, with a maximum of 4 points per group. This
module has a fused IFM that can be used to protect outputs. It is
recommended to use only a 5x20mm 4A quick acting-fuse that is
supplied by SOC p/n MQ2-4A for this module. Note that it is
important to ground and install the chassis and power supply before
installing the module with the required RTB, which can either be
the 1756-TBNH or the 1756-TBSH (20 pins RTB).
This module has the following communication formats available: rack
optimization, listen-only - rack optimization, output data,
listen-only output data, and scheduled output data. Pilot duty is
also available for the 1756-OB8 module.
The 1756-OB8 module has a voltage category of 12/24 volts DC source
and an operating range of 10 to 30 volts DC. Its current draw is
165 mA at 5.1V and 2 mA at 24V. It has a backplane power of 0.89 W,
with a maximum dissipation of 2.5 W at 60 Degrees Celsius (140
degrees Fahrenheit), and a thermal dissipation of 8.53 BTU/hr. The
maximum off-state leakage current of this module is 1 mA per point
and during an on-state, it has a maximum voltage drop of 1.2V DC at
2 A. It also has a maximum current of 2 A per point at 60 Degrees
Celsius and a maximum current of 8 A at 60 Degrees Celsius per
module. Its surge current per point is 4 A for 10 ms each that is
repeatable every 1 s at 60 Degrees Celsius and its minimum load
current is 2 mA per point. The module's isolation voltage is
continuous at 250V.
