About the 1769-OB32

The 1769-OB32 is used with Allen Bradley’s MicroLogix 1500 and 1769 CompactLogix family of controllers. This module has Thirty-Two (32) 24VDC output channels for use with DC loads such as solenoid driven actuators, motor actuators, relays, pilot lamps, audio/visual alarms and other devices. The module has Two (2) input group with Sixteen (16) channel each. These channel groups are isolated and operate on a sourcing output configuration. It comes with a 1769-RTBN18 removable terminal block for modularity. Connect the +DC of the signal device to the +VDC and the -DC to the DC COM terminal of the module. Output modules have built-in protection for surge suppression and voltage transients. An external transient and suppression protection can be installed to protect the module from damage. Leakage current may be prevented by connecting in parallel a 5.6 k?, ½ W resistor. The 1769-OB32 is configurable with RSLogix 500, RSLogix5000 or Studio 5000 programming software. The module’s configurable parameters such as module inhibition, packet interval, slot assignment and revision number provide a convenient way to fine tune the operation of the module. Further parameterization can be done by accessing the module’s input data files. The data files store the status of the input addresses as well as module diagnostics. Install the output module not more than Eight (8) modules away from the power supply. There is no limit to the number of modules that can be used as long as the power supply distance rating is observed. The module can be inserted to any adjacent I/O module including the controller in the chassis. Module mounting can be done using on a 35 X 75 or 35 X 15 mm DIN rail. When installing the module, remove power from the backplane by turning off the power supply as electric arcs may occur during the locking of bus levers. Implement grounding by connecting the mounting surface to a grounding bar or a grounded metal panel.
