Product Summary
The Allen-Bradley 1762-OF4 is a MicroLogix analog output module. It delivers four single-ended channels for voltage or current signals. This module drives modulating actuators and VFDs with high accuracy. Engineers use it for precise industrial process control.
Expert Technical Evaluation & Performance Review
Signal Processing and Accuracy
The 1762-OF4 uses an R-2R ladder DAC for signal conversion. This design provides a 12-bit unipolar resolution. The module achieves a repeatability of ±0.12%. At 25°C, the typical overall accuracy is ±0.5% full scale. This accuracy includes gain, offset, and non-linearity errors.
Output Range and Flexibility
This module supports multiple output configurations for voltage. You can select 0-10V DC, 0-5V DC, or ±10V DC ranges. For current outputs, it supports 0-20mA and 4-20mA signals. The full-scale analog ranges extend to 0…10.5V DC and 0…21 mA. This flexibility allows it to drive various field devices.
Load Handling and Protection
The module handles specific load types for each output mode. For current outputs, the resistive load range is 0 to 500 ohms. The reactive load for current must be less than 0.1 mH. For voltage outputs, the load must exceed 1 K? with a reactive load under 1 µF. The output protection value is ±32 mA, safeguarding the module.
Environmental Tolerances
The 1762-OF4 operates across a wide temperature range. It functions from -20°C to 65°C with an accuracy of ±1.17% full scale. At 25°C, the accuracy improves to ±0.5%. The module dissipates only 2.8 Watts of heat. This low heat output ensures stable performance in control panels.
Installation and Wiring Guide
Mount this module horizontally on a grounded metal panel. Use Belden 8761 shielded cable for all analog wiring. This cable is sensitive to electrostatic discharge (ESD). Always follow ESD prevention guidelines during installation. The module requires a 24 Volts DC input power supply.
Compatibility with Controllers
This module works with MicroLogix 1100, 1200, and 1400 controllers. You can install up to four modules with a MicroLogix 1100. The MicroLogix 1200 supports up to six modules. For the MicroLogix 1500, you can use up to seven modules. This scalability allows for system expansion.
