Information About 1756-OF4
The Allen-Bradley 1756-OF4 is a high-performance, non-isolated analog output module within the ControlLogix platform. It provides four individually configurable voltage or current outputs suitable for delivering precise control signals to actuators, control valves, variable-speed drives, chart recorders, indicators, and external control systems. Each channel supports output ranges of ±10V DC or 4–20 mA, with high-resolution conversion (15 bits). With its accurate DAC architecture and monotonic output performance, the module ensures dependable analog control in complex process and motion applications. The 1756-OF4 supports multiple data formats including integer and floating-point, enhancing flexibility across platform applications.
Key Features:
- Four independently configurable analog output channels
- Supports ±10V DC and 4–20 mA ranges
- High-resolution conversion (15 bits)
- Suitable for modulating actuators, VFDs, valves, indicators, and loggers
- Supports floating-point and integer data modes
- RIUP (Removal and Insertion Under Power)
- Compatible with 1756-TBSH and 1756-TBNH RTBs
- Fast update and settling time (<2 ms)
- 50V continuous isolation
- Integrates with ControlLogix producer/consumer communication
A versatile, high-resolution 4-channel analog output module for ControlLogix systems, providing both current and voltage outputs for advanced industrial control applications.
