Description of 1746-OX8
The Allen-Bradley 1746-OX8 is a contact output module under the SLC
500 family of programmable controllers. The 1746-OX8 has 8 isolated
high-current relay contact outputs. It has an operating voltage
ranging between 5-125V DC and 5-265V AC. Additionally, the 1746-OX8
operates at a backplane current of 85mA at 5V DC and 90mA at 24V
AC. The heat dissipation for the module is 0.825W per point.
Minimum dissipation measures at 2.590W with a total of 8.60W.
The 1746-OX8 has a maximum resistive load single delay of 10.0ms
when ON and 10.0ms when OFF. Backplane current consumption for the
module is 0.085A at 5V DC and 0.090A at 24V DC. In addition, the
module has a 0mA maximum off-state leakage and a minimum load
current of 10mA at 5V DC. The continuous current per module must be
limited to prevent the module power from exceeding 1440VA. The
1746-OX8 has a relay contact rating of 30A at 120V AC maximum with
a break of 3.0A at 240V AC, and a relay contact rating of 15A with
a break of 1.5A. In addition, the 1746-OX8 has a relay contact
rating of 0.22A and 1.2A at 125V DC and 24V DC respectively.
The 1746-OX8 has a Class 1, Division 2 endorsement to be used in a
hazardous environment. The operating temperature for the 1746-OX8
ranges between 0-60º C (32-140º F) and the non-operating
temperature ranges between -40-85º C (-40-185º F) at 5-95%
non-condensing operating humidity. The module adheres to the CS-232
NEMA standard for noise standards. The 1746-OX8 has an operating
vibration displacement of 0.015” peak at a speed of 5-57 Hz with an
acceleration of 2.5g at 57-2000Hz. It has an operating shock of 10g
and a 1500V isolation.
About 1746-OX8

isolated relay output module. The operating temperature range for
the module is 32 to 140 degrees Fahrenheit. The non-operating
temperature range is -40 to 185 degrees Fahrenheit. The recommended
non-condensing operating humidity range is 5 to 95%. The rated
noise immunity meets the NEMA ICS 2-230 standard. The operating
vibration rating is 0.015 inches of displacement at 5 to 57 Hertz.
The operating shock rating for the 1746-OX8 module is 10 g. the
module is certified by the UL, CSA, and CE standards. The rated
heat dissipation per energized point for the module is 0.825 Watts.
The minimum heat dissipation when no field power is applied is 2.59
points. The total heat dissipation for the module when all the
outputs are energized is 8.6 Watts.
The 1746-OX8 module has 8 individually isolated outputs. At 24
Volts DC backplane voltage, the module consumes 0.09 Amps of
current and at 5 Volts DC backplane voltage, the module consumes
0.085 Amps. In the on-state the signal delay with a maximum
resistive load is 10 milliseconds. In the off-state, the signal
delay for the maximum resistive load is 10 milliseconds. The
operating voltage range with a 5 Volts DC supply is 5 to 125 Volts
and with a 24 Volts DC supply, it is 5 to 265 Volts. The peak
off-state leakage is 0 milliamps. The minimum level of recommended
load current is 10 milliamps at 5 Volts DC. At 120/240 Volts AC,
the continuous current per point is 2.5 Amps. At 125 Volts DC, the
continuous current per point is 1 Amp and at 24 Volts DC, the
continuous current per point is 2 Amps.
