Allen-Bradley 1756-OFE3 is an analog output module for the ControlLogix controller platform. The module primarily has eight (8) voltage or current output channels that can be configured for 0-20 mA and 4-20 mA current output signals and +/-10VDC voltage output signals. The 1756-OF8H has a module resolution of 15-16 bits across all signal ranges. It comes with an internal digital-to-analog converter (DAC) using an R ladder DAC, monotonicity, lossless conversion method, and data format in integer mode (left-justified, 2-second complement) IEEE 32-bit floating point. This module is installed in the 1756 ControlLogix chassis and occupies only a single slot. It can be used as a local IO module and a remote I/O module component. For terminating signal lines, the module is equipped with a detachable terminal (RTB).

This RTB can be replaced with 1756-OFE3 or 1756-TBSH with user-defined mechanical RTB keying. When using 1756-OFE3, the applicable wire size for a single wire connection is 0.33-2.1 mm2 (22-14 AWG), 0.33... 1.3mm 2 (22... 16 AWG) for two-wire connections. The 1756-TBSH supports single wire connections only and is designed for wire 0.33... 1.3mm 2 (22... 16 AWG) Wire size. The 1756-OFE3 has a continuous isolation voltage rating of 50V. Module isolation is only between the output channel and the backplane. Each output channel does not have a separate isolation. In addition, the module's open circuit detection time is only available in current configurations, with a maximum overvoltage protection of +/ -24 VDC.

Allen-Bradley's 1756-OFE3 ControlLogix Voltage/current analog output module is an analog output module with eight voltage or current outputs, each with only one HART modem. It has an optional voltage/current signal range of -10.4336-10.4336V and 0-21.2916mA. The 1756-OFE3 has a total output rating of +/- 10V or 0-20mA and a signal resolution of 15-16 bits across all ranges. It also has backplane current consumption of 230 mA @ 5.1 VDC and 230 mA @ 24 VDC for a total backplane power of 6.54W. It has a heat dissipation of 16.78 BTU/hr and a power consumption of 4.92W. The 1756-OF8H has an isolation voltage of 50V and a 60-second basic insulation test at 1500V AC between the output channel and the backplane.
