Functional features
1. Multi-channel independent control and high flexibility
Allen-Bradley 1756-OF8 provides 8 fully isolated analog output channels, each of which can be independently configured as voltage or current mode.
By flexibly adapting to different devices, the module can control multiple actuators at the same time, reducing system complexity and wiring costs.
2. High precision and temperature stability
Allen-Bradley 1756-OF8 uses 15-bit resolution and ±0.05% calibration accuracy, combined with temperature drift compensation technology to ensure long-term stability in extreme temperature environments.
3. Redundant protection and safety mechanism
Allen-Bradley 1756-OF8 has built-in multiple protection functions:
Support ControlNet and EtherNet/IP redundant communication to prevent communication interruption
Electronic current limiting (≤21mA) and short-circuit protection to avoid equipment damage
24V DC overvoltage protection to enhance reliability in industrial environments
4. Fast response and wide compatibility
Allen-Bradley 1756-OF8 achieves real-time control with 2ms signal setup time and 8ms scanning speed, suitable for high-speed production lines and dynamic adjustment scenarios.
Compatible with ControlLogix series controllers, third-party devices and removable terminal boards, and supports RIUP function.
