Unlike standard mixed-signal modules, the 1769-OF8C is dedicated exclusively to current outputs, providing 8 independent channels in a single-width package. This makes it the ideal solution for applications requiring precise control of multiple control valves, variable frequency drives (VFDs), or other current-driven field devices.Key Features & BenefitsHigh-Density Current Output: Features 8 independent analog output channels, all configured for current signals. This high density maximizes panel space efficiency for current-loop applications.16-Bit Precision: Delivers high-resolution 16-bit digital-to-analog conversion, ensuring extremely accurate and smooth control of field devices.Open Loop Detection: A standout feature of the 1769-OF8C is its ability to detect open loop (wire break) conditions. The module can alert the controller if a field wire is disconnected, allowing for immediate fault handling and improved safety.Versatile Current Ranges: Supports both 0 to 20 mA and 4 to 20 mA (with a range up to 21 mA for saturation) output ranges, configurable via software.Diagnostic LEDs: The front-mounted OK LED indicates module health and can flash to indicate specific fault conditions, such as open loops or configuration errors, simplifying troubleshooting.Robust Design: Built to operate in temperatures from 0°C to 60°C, ensuring stability in harsh industrial environments.ApplicationsThe Allen-Bradley 1769-OF8C is extensively used in:Process Control: Driving multiple control valves and positioners via 4-20mA signals.Motor Control: Sending speed reference signals to multiple VFDs.Actuator Control: Managing analog actuators in water/wastewater treatment.Data Acquisition: Interfacing with current-input chart recorders.Important Installation Note:The 1769-OF8C module does not include the terminal block. You must order the 1769-RTBN10 (screw type) or 1769-RTBN10P (spring type) separately for wiring. Ensure the external 24V DC power supply is correctly connected for current operation.Why Choose This Module?Our 1769-OF8C units are sourced from authorized distributors, guaranteeing genuine Allen-Bradley / Rockwell Automation quality. Its specialized current-output design and open-loop detection make it a superior choice for critical process control loops. We provide fast shipping, technical support, and competitive pricing.Optimize your CompactLogix current control with the Allen-Bradley 1769-OF8C.Compact 1769-OF8C Analog Output Module Installation InstructionsPublication Type: Installation Instructions Published Date: Jul 2, 2010Language: EnglishCompact I/O Analog Modules User ManualPublication Type: User Manual Published Date: Jul 12, 2005Language: English1769 Series Computers and Programmable Logic Controllers (PLC) – ABS certificatePublication Type: CertificationPublished Date: Mar 16, 2023Language: English1769 Compact I/O Modules SpecificationsPublication Type: Technical DataPublished Date: Nov 18, 2023Language: EnglishCompactLogix I/O, 1769 Series – CE DoCPublication Type: CertificationPublished Date: Nov 28, 2022Language: English1769 Series CompactLogix I/O – UKCA DoCPublication Type: CertificationPublished Date: Oct 3, 2022Language: English1769, 1794, and 1756 I/O Modules, Analog Input Modules, Haz Loc – UL CoCPublication Type: CertificationPublished Date: Jun 13, 2008Language: EnglishCompact I/O 1769 Series and Accessories – RCM DoCPublication Type: CertificationPublished Date: Jun 1, 2018Language: English
