The Allen‑Bradley 1769‑OF2 is a compact analog output module that offers two isolated, single-ended channels. Specifically, this module generates both voltage and current outputs to meet diverse application needs. For instance, you can configure it for ±10V DC, 0 to 10V DC, 0 to 5V DC, or 1 to 5V DC. Meanwhile, it also supports standard current loops like 0-20 mA and 4-20 mA. Therefore, this flexibility makes the 1769‑OF2 suitable for a wide range of field devices and control scenarios.
The module integrates a sigma-delta Digital-to-Analog converter for precise signal generation. Consequently, it achieves a resolution of 14 bits (unipolar) and 14 bits plus a sign bit for ± (plus/minus) ranges. Specifically, the conversion rate is just 2.5 ms, while the step response completes within 2.9 ms. Moreover, this rapid response ensures precise control for demanding PID loops and fast-acting processes.
Accuracy remains a critical factor for this device. At 25 °C, the voltage accuracy is ±0.5% of full range. For current outputs, the accuracy reaches ±0.35% under the same conditions. Additionally, the module error boundary is a low 0.8%, with an accuracy drift of only ±0.0086% per degree Celsius. Therefore, this module maintains stable performance even in fluctuating temperatures. Furthermore, its repeatability and nonlinearity margins are both rated at ±0.05%, guaranteeing consistent operation over time.
Each channel on the 1769‑OF2 can drive a variety of loads without difficulty. For voltage outputs, the minimum load resistance is greater than 1 kΩ at 10V DC. For current outputs, the resistive load range is 0 to 500 Ω, including wire resistance. Furthermore, the module handles an inductive load of up to 0.1 mH per current output. For voltage outputs, the capacitive load is limited to 1 µF. These specifications allow the 1769‑OF2 to interface reliably with most common actuators, valves, and signal receivers. Besides that, the output impedance is rated at 15 Ω, which ensures proper signal transfer.
Reliability is enhanced through built-in protection circuits. The 1769‑OF2 includes short-circuit protection with a maximum current limit of 21 mA. It also features over-voltage protection to safeguard the module and connected devices. Moreover, it offers a fast open-wire detection time of just 10 ms. This diagnostic capability helps maintenance teams quickly identify wiring faults, thereby reducing system downtime significantly. In addition, the offset error margin is only ±0.05%, which contributes to overall measurement integrity.
The 1769‑OF2 comes in a single-slot width form factor. Its physical dimensions are 4.65 x 1.38 x 3.43 inches, and it weighs approximately 0.65 pounds. You can mount it on a standard DIN rail or directly onto a panel. For wiring, the module uses solid copper wire sizes ranging from 22 to 14 AWG. Its heat dissipation is rated at 2.36 W, and it draws 120 mA at 5.1V from the backplane. Notably, the power supply distance rating is 8, which simplifies system layout and planning.
Installation of the 1769‑OF2 is straightforward and user-friendly. First, secure the module to the DIN rail or panel using standard mounting hardware. Next, connect the wiring using the recommended 22-14 AWG solid copper wire. For replacement parts, the terminal block is the 1769-RTBN18, and the replacement door is the 1769-RD. This module is compatible with MicroLogix 1500 and CompactLogix controllers. It also works seamlessly in systems running CompactLogix version 20 or later. Best of all, no field calibration is ever required, as the hardware design guarantees long-term accuracy.
