About the 1769-OB16P

The 1769-OB16P is used with Allen Bradley’s 1769 CompactLogix family of controllers. This module has Sixteen (16) 24VDC electronically fused output channels for controlling DC loads such as solenoid actuated valves, relays, pilot lamps, audio/visual alarms and other actuating devices. Output modules have built-in transient voltage suppressors. An external transient suppression 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 module comes with a 1769-RTBN18 removable terminal block for modularity. It only supports sourcing configuration thus, connect the V+ of the incoming input signal to the +VDC terminal and the DC COM to the -DC. The power supply distance rating of 1769-OB16P is 8 modules. There is no limit to the number of modules that can be used as long as the distance rating is observed. The module can be inserted to any adjacent I/O module including the controller in the chassis. The 1769-OB16P can be installed on a MicroLogix 1500 and CompactLogix chassis. Configure the settings of the 1769-OB16P with the RSLogix500 software for MicroLogix and RSLogix5000 or Studio 5000 programming software when using CompactLogix. 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. The module can be mounted 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. The mounting surface of the module must be properly grounded by connecting to a grounding bar or a grounded metal panel.
