The AB 1756-OF8 is an analog output module that is part of the
ControlLogix platform. This analog module may be used to control
and modulate electrical and field devices, transmit or re-transmits
signals for interfacing with measuring and recording instruments or
for any other purpose.
The 1756-OF8 comes with Eight (8) analog output channels
configurable for +/-10VDC and 0-20 mA analog output signals. It has
a resolution of 15 bits across 21 mA - 650 nA/bit and 15 bits
across 10.4V - 320 µV/bit with open circuit, short circuit and
overvoltage protection capability.
The 1756-OF8 uses R-Ladder DAC, monotonicity with no missing codes
module conversion method and provides register data in the form of
Integer mode (left justified, 2 s complement) IEEE 32-bit floating
point. It has a scan time of 12 ms for floating point format and 8
ms for integer format.
The 1756-OF8 requires removable terminal blocks for wiring of input
signals. Appropriate terminal blocks are 1756-TBNH and 1756-TBSH.
For 1756-TBNH, applicable wire size is 0.33…2.1 mm2 (22…14 AWG)
solid or stranded copper wire, rated at 105 °C (221 °F) or greater,
1.2 mm (3/64 in.) insulation max. for single wire connection and
0.33…1.3 mm2(22…16 AWG) solid or stranded copper wire, rated at 105
°C (221 °F) or greater, 1.2 mm (3/64 in.) insulation max. for
double wire connection. When 1756-TBSH is used, appropriate wire
size is 0.33…2.1 mm2 (22…14 AWG) solid, or stranded shielded copper
wire rated at 105 °C (221 °F), or greater, 1.2 mm (3/64 in.)
insulation max. Only single wire connection is applicable for the
1756-TBSH.
When operational, it has an offset drift of 50 ppm/degrees Celsius
and 0.1 ppm/degrees Celsius and temperature-dependent gain drift of
25 ppm/degrees Celsius and 50 ppm/degrees Celsius (current). The
module has a scan time of 12 milliseconds for floating point and 8
milliseconds for integer and has an overall module error of 0.15%
(in voltage mode) and 0.3% (in current mode). The1756-OF8 module
has an isolation voltage of 250 Volts using reinforced insulation
tested 1350 Volts AC for 2 seconds between the output channels and
the backplane. It has a T4A (North America), T4 (ATEX), and T4
(IEC) temperature codes and comes in an open-style enclosure. The
1756-OF8’s operational temperature ranges between 0 and 60 degrees
Celsius and it is designed to maintain its function at a shock rate
of 30G and a vibration of 2G at 10 to 500 Hertz.

Where can I send the 1756-OF8 to be repaired?
DO Supply, Inc. offers a variety of repair services for the
1756-OF8.
How many output channels does the 1756-OF8 have?
The 1756-OF8 has Eight (8) analog output channels.
What is the resolution of the 1756-OF8?
The 1756-OF8 has 15 bits across 21 mA - 650 nA/bit and 15 bits
across 10.4V - 320 µV/bit resolution.
Does this module come with individual channel isolation?
No. The module with individual isolation id 1756-OF8I.
