1756-OF8 Description

The 1756-OF8 is an analog output module that is part of the 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.
