About 1769-L23-QBFC1B

The 1769-L23-QBFC1B is a CompactLogix Packaged controller that belongs to the 5730 L2 CompactLogix product family. This device is an out of the controller, complete with features that allow the unit to function immediately as it is built with an embedded power supply, I/O interfaces, communication ports and controller end cap. The 1769-L23-QBFC1B has an embedded power supply designed for nominal supply voltage of 24VDC with voltage range of 19.2 to 31.2V DC and maximum line requirement of 50 VA at 24V DC. This power supply is designed to provide power to the CompactLogix bus having an output current of 2A at 5V DC and 0.8A at 24V DC at temperature of 0-55 Deg. Celsius. This embedded power supply has an embedded front access fuse used for short circuit protection. The embedded discrete input channels amount to Sixteen (16) input points, compatible for sinking wiring configuration and designed to received nominal input signal of 24VDC with operating voltage range of 10 to 30V DC at 30 C or 86F and 10 to 26.4V DC at 60 C at 140F. These input channels have individual digital filter which include 0 s, 100 _s, 500 _s, 1 ms, 2 ms for OFF to ON transition and 0 s, 100 _s, 500 _s, 1 ms, 2 ms for ON to OFF transition. The input channels exhibit a typical hardware delay of 100 _s while the maximum delay is 300 _s for OFF to ON transition and typical of 250 _s and maximum of 1 ms for ON to OFF transition. The embedded output channels amount to Sixteen (16) 24VDC sourcing outputs with output operating voltage range of 20.4V DC to 26.4V DC. Each output channels has turn on time of 0.1 ms and turn off time of 1.0 ms for resistive load. The maximum continuous current per point varies depending on the environmental temperature such as 0.5A at 60 C or 140 F and 1.0A at 30 C or 86 F while the maximum continuous current per module are 4.0A at 60C or 140 F and 8.0A at 30 C or 86 F. There are no channel isolation provided as the commons are internally connected. The analog input and output channels are designed for 0-10VDC and 4-20mA signals. The set of analog I/O allows the controller to control analog control loops for implementing a more accurate and efficient control. The analog input channels amount to Four (4) single ended or differential input channels while the output channels are purely single ended outputs. The controller is also supplied with High speed counter channels that enables the controller to be installed in motion control and high-speed counting applications. High-speed counters are compatible for differential and single ended wiring which may be used for a variety of encoders, counters, data loggers, totalizers and other similar devices. The controller has an embedded 512Kbyte volatile memory which uses a 1769-BA battery for memory data retention. Only the 1769-BA may be used with this controller. Although the 1747-BA may look similar in terms of physical form, never use this unit with the 1769-L23-QBFC1B.
