About 1769-OF4

The 1769-OF4 is used with Allen Bradley’s MicroLogix 1500 and 1769 CompactLogix family of controllers. This module has Four (4) single-ended output channels configurable for 0-20mA, 4-20 mA, ±10V dc, 0 to 10V dc, 0 to 5V dc, 1 to 5Vdc. Analog outputs drive modulating actuators and devices allowing multiple points and control and increased accuracy and precision. The module converts the Digital data from the CPU to Analog signal via the Digital to Analog Circuit (DAC) built-in with the module. The converted signal are sent to the analog output module. Configure the module using RSLogix500 when used with a MicroLogix500 controller. When using CompactLogix processor, configure the module using RSLogix5000 or Studio5000 programming software. Individual channel configuration can be performed in the software including enabling of channels, output range selection, data format, 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 can be accessed. 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-OF4 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-OF4 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.
