1769-OF4CI Allen-Bradley Analog Current Output Module

Allen-Bradley 1769-OF4CI 4-Channel Isolated Analog Current Output Module

• Output Ranges and Resolution – the 1769-OF4CI supports 0-20 mA and 4-20 mA output signals. Full-scale analog ranges are 0-21 mA and 3.2-21 mA respectively. Digital resolution reaches 16 bits unipolar, with 0.323 µA per bit for both ranges.
• Channel Configuration – each of the four channels is individually isolated and differential. You can configure output range selection, module inhibition, module description, and slot assignment per channel.
• Data Formats – the module supports multiple data formats including raw or proportional data, engineering units, scaled for PID, and percent full range. This flexibility simplifies programming across different controller platforms.
• Accuracy and Linearity – accuracy measures ±0.35% of full scale. Non-linearity is ±0.05% of full scale, with repeatability at ±0.005%. Accuracy drift with temperature is ±0.0058% FS per degree Celsius.
• Conversion Rate – the 1769-OF4CI delivers a conversion rate of 110 milliseconds per channel. This response time suits process control applications requiring stable analog output updates.
• Auto-Calibration and Self-Test – the module performs auto-calibration automatically during each power cycle. A self-test runs at startup, after which the module enters active operation with high and low clamp settings actively limiting outputs.
• Protection Features – built-in open circuit and short circuit protection safeguard the module and connected devices. Output excess voltage protection and a maximum short circuit current of 21 mA ensure robust operation.
• Load Specifications – resistive load range is 0 to 500 Ohms. Output inductive load rating is 0.1 mH. Output impedance measures less than 1 MOhm.
• Backplane Power Consumption – this module draws 165mA from the 5V DC backplane supply. Heat dissipation is rated at 2.0 Watts.
• Power Supply Distance Rating – the 1769-OF4CI carries a power supply distance rating of 8 modules. Place it within 8 modules of the system power supply for reliable operation.
• Environmental and Physical Specifications – operating temperature ranges from 0 to 60 °C (32 to 140 °F). Storage temperature spans -40 to 85 °C (-40 to 185 °F). Dimensions are 118 x 35 x 87 mm (4.65 x 1.38 x 3.43 in.), with a weight of 270 g (0.60 lb). Shipping dimensions are 8 x 8 x 5 inches with a weight of 2 lbs.
• Wiring and Cabling – use copper wire with stranded sizes from 22 to 16 AWG or solid sizes from 22 to 14 AWG. Recommended cable is Belden 8761 shielded cable for optimal noise immunity.
• Mounting Options – you can mount the 1769-OF4CI on a DIN rail or directly on a panel. The replacement door part number is 1769-RD.
