Product Procurement & Buyer Guide
The 1762-OF4 module directly solves control loop challenges by offering four single-ended analog outputs. You can configure each channel for voltage or current, supporting 0-10VDC and 4-20mA ranges. This flexibility allows precise modulation of valves, VFDs, dampers, and louvers.
Procurement managers benefit from its compatibility with MicroLogix 1100, 1200, and 1400 controllers. You can install up to seven modules in a MicroLogix 1500 system. The module uses a 24VDC input power and dissipates only 2.8 W of heat.

Application engineers avoid signal drift with a repeatability of ±0.12% and overall accuracy of ±0.5% at 25°C. The output protection of ±32 mA safeguards connected devices. This makes the 1762-OF4 a reliable choice for demanding industrial environments.
Expert Technical Evaluation & Performance Review
The 1762-OF4 uses an R-2R ladder DAC for digital-to-analog conversion. Its resolution is 12 bits unipolar, delivering fine granularity for control signals. The output time of 2.5 milliseconds ensures responsive loop updates.
Accuracy includes gain, offset, non-linearity, and repeatability errors. At 65°C, the module maintains ±1.17% full-scale accuracy. The resistive load on current outputs ranges from 0 to 500 ohms, while voltage outputs require >1 KΩ load.
Heat dissipation of only 2.8 W reduces thermal stress in the cabinet. The module must be mounted horizontally on a grounded metal panel. Always use Belden 8761 shielded cable and follow ESD precautions during wiring.
