About the 1769-OF4CI
The 1769-OF4CI is used with Allen Bradley’s MicroLogix 1500 and 1769 CompactLogix family of controllers. This module has Four (4) differential output channels configurable for 0-20mA and 4-20 mA. Each channel provide isolation so as not to affect individual operation. Each channel can be operated with different power sources. Analog outputs are used drive modulating actuators and devices allowing multiple points and control and increased accuracy and precision. The module has a built-in Digital to Analog converter that converts the Digital data format stored in the CPU to Analog signal. Data formats are configured using RSLogix500 when used with a MicroLogix500 controller, RSLogix5000 or Studio5000programming software when used with CompactLogix controller. Data formats are defined to characterize the output of the controller according to its external use. Data formats available are Raw / Proportional data, Engineering unit, Scaled for PID and Percent full range. Other important parameters offered by the module include enabling of channels, output range selection, module inhibition, module description and slot assignment. The module generates a unique data table for each instance of installation where the channel addresses, module mode bits, module state and other runtime parameters. The module performs self-test in the event when module is power cycled. During the power cycle phase, the module may have no indication until the completion of the self-test. Once in active operation, each new value in the output module is compared to the set high and low clamps. High and low clamps prevent the analog output from exceeding the set limits. Install as many 1769-OF4CI as required in a MicroLogix 1500 controller or CompactLogix chassis with reference to the power supply distance rating of 8 modules. More advanced CompactLogix processor may support more than 16-30 module in the local chassis. Should more than 8 instances of 1769-OF4CI is needed, an appropriate system or bank power supply is required. The module can be inserted to any adjacent I/O module including the controller in the chassis. Install the module by locating the guide slots of the adjacent module. Slide the module and establish alignment of the bus connectors. Once bus connectors are aligned, move the bus lever to the left until a clicking sound is created.
