About 1769-L23-QBFC1B

The Allen-Bradley 1769-L23-QBFC1B is a CompactLogix packaged controller. Ideal for serial connections, it has a total of 42 available channels, 16 digital inputs, 16 digital outputs, 4 differential or single-ended analog inputs, 2 single-ended analog outputs, and 4 high-speed counters. LED status indicators let the users monitor the current state of the controller, power supply, module, network, link, RS-232 serial port, analog and digital I/O, and a high-speed counter.

The 1769-L23-QBFC1B has an open-style enclosure and it can mount on a DIN rail or panel mount. It also comes with a 512 KB of user memory and it supports a variety of programming languages including ladder diagram, function block, structured text, and sequential function chart. This module has 3 total available tasks with 16 total programs or equipment phases per task and it is programmed and monitored using the RSLogix 5000 programming software. The 1769-L23-QBFC1B measures 4.13 x 9.82 x 4.65 inches and uses a 1768-BA battery, which is user-replaceable. Features of the 1769-L23-QBFC1B controller include isolated and non-isolated serial connections, a capacity for expansion I/O, configurable embedded I/O, and network configuration and monitoring via RSLinx and RSNetWorx software. Two RS-232 ports in the controller allow operators to use an ASCII or DF1 protocol. Note that the users need to limit the length of the connected serial cable to 50 feet. The response time from OFF to ON is a maximum of 400 milliseconds and from ON to OFF is a maximum of 200 milliseconds. The 1769-L23-QBFC1B controller has input ranges of 10 to 30 Volts DC, +/-10 Volts, 0 to 0.5 Volts, 0 to 5.25 V, and 0 to 21 mA, while the output ranges are 24 Volts DC, +/- 10.4 Volts, and 0 to 21 mA. The voltage ratings of the module are 24 Volts DC sink/source, 10 to 30 Volts DC at 0 degrees Celsius, and 10 to 26.4 Volts DC at 60 degrees Celsius and its continuous isolation voltage from channel 0 to the system backplane, with no isolation between RS-232 channel 1 and system, is 30 Volts. It also comes with a power dissipation of 10.73 W and a non-condensing relative humidity of 5 to 95%. The controller has an operating vibration of 2 g, an operating shock of 30 g, and a non-operating shock of 50 g.

The Allen-Bradley 1769-L23-QBFC1B is a CompactLogix controller from Allen-Bradley. This assembly is specifically a CompactLogix packaged controller that comes with complete components, functioning as a full Programmable Automation Controller (PAC).

The 1769-L23-QBFC1B comes with embedded power supply with nominal input supply voltage of 24 Volts DC. This power supply delivers power to the backplane, energizing other embedded components of the assembly. This controller also comes with available user memory amounting to 512 KB and two (2) RS-232 ports with 1 port acting as isolated DF1, DH-485 or ASCII interface and the other port as non-isolated DF1 or DH-485 only. Both ports support up to 38.4 Kbps transmission speed. For expansion, this packaged controller supports installation of an additional two (2) 1769 Compact I/O modules.

The 1769-L23-QBFC1B also comes with embedded I/O channels. It has a total of 42 I/O channels, composed of sixteen (16) 24 Volt DC inputs; sixteen (16) 24 Volt DC outputs; four (4) differential or single-ended 0-10.5 / 4-20 mA inputs; two (2) single-ended 0-10 Volt DC / 0-21 mA analog outputs and four (4) high-speed counter modules.

The 1769-L23-QBFC1B supports direct panel mounting or using a DIN rail. For wiring DC input supply, the recommended cable for use is 0.25…2.5 mm2 (22…14 AWG) solid or stranded copper wire with an insulation rating of 75 °C (167 °F) or higher and maximum insulation thickness of 1.2 mm (3/64 in.). For I/O signals, 0.5…0.8 mm2 (20-18 AWG) solid or stranded copper wire with insulation rating of 75 °C (167 °F) or higher and maximum insulation thickness of 1.2 mm (3/64 in.).
