Rockwell Allen-Bradley Analog Output Module 1756-OF4/AModule
About1756-OF4:
The Allen-Bradley 1756-OF4 module is a ControlLogix non-isolated output module.
1756-OF4has 4 voltage or current outputs available with a current resolution of 15 bits across 21 mA, 650 nA/bit for a voltage resolution of 16 bits across 10.5V, 320 µV/bit. It requires a 20 pin RTB, or Removable Terminal Block housing for connection to field devices. The compatible RTBs are the 1756-TBSH and the 1756-TBNH. It is important to ensure that the chassis and power supply have already been installed and grounded prior to installing the module to it with the RTB.
