Allen-Bradley 1769-OF8C
The Allen-Bradley 1769-OF8C is a Compact I/O analog output module designed for seamless integration with 1769 and select 1768 CompactLogix controllers, as well as the MicroLogix 1500 controller. It features eight single-ended current output channels configurable for 0-20 mA and 4-20 mA, supported by a 16-bit Digital to Analog Converter for high-precision signal conversion. With a fast conversion rate of 5ms and robust protection features such as overcurrent and overvoltage safeguards, the 1769-OF8C is ideal for driving various final control elements, including modulating control valves and variable frequency drives, within automatic control loops. This module includes convenient features such as a status LED, a removable terminal block with finger-safe protection, and channel-to-earth ground isolation, requiring a 24 Volts DC rated external power supply. Designed to operate effectively within a temperature range of 0 to 60 degrees Celsius, it maintains an output accuracy of ±0.35% at 25 degrees Celsius, ensuring reliable performance across demanding industrial environments.Technical specifications for 1769-OF8C Series 1769 Compact I/O Module Type Analog Output Module Part Number/Catalog No. 1769-OF8C Brand Allen-Bradley Manufacturer Rockwell Automation No. of Outputs Eight (8) Current outputs Output Current 0-20 mA / 4-20 mA Output Current Range 0-21 mA; 3.2 mA - 21 mA Resolution 16 bit Conversion Rate (all channels) max. 5 ms Overall Accuracy ±0.35% full scale at 25 °C Open and Short-Circuit Protection Yes Maximum Short-Circuit Current 21 mA Current draw 145 mA at 5VDC; 185 mA at 24V dc Channel Diagnostics Over- or under-range by bit reporting output wire broken or load resistance high by bit reporting Enclosure None Product Line CompactLogix Input Type Output Current Communication Cable 8 Point Shipping Weight 2 pounds Shipping Dimensions 8 x 8 x 5 inches Converter Type Delta Sigma Outputs 8 single-ended Replacement Door Part Number 1769-RD Wire Type Copper-90 degrees Solid Wire Size 22 to 14 AWG Stranded Wire Size 22 to 16 AWG Heat dissipation 2.69 Watts UPC 10662468861622
