Information About 1761-L16BBB

The 1761-L16BBB is an Allen-Bradley product that belongs to the MicroLogix 1000 Programmable Logic Controllers (PLC). This electronic device is ideal for installation in an industrial environment for implementing micro and small automation requirements of simple scale applications. Specifically, the MicroLogix 1000 is compatible with machine control applications.

The 1761-L16BBB is a compact controller. Compact controllers refer to a PLC device with embedded input and output, integral power supply and communication ports. Specifically, the 1761-L16BBB has Ten (10) discrete 24VDC inputs, Four (4) Transistor outputs and Two (2) relay output channels. Additionally, it has an 8-Pin mini-DIN terminal that is designed for the RS232 interface. This RS232 interface is capable of Allen-Bradley DF1 protocol.

Specific Allen-Bradley cables for use with this controller include 1761-CBL-PM02 Series C 1761-CBL-HM02 Series C 1761-CBL-AM00 Series C 1761-CBL-AP00 Series C 1761-CBL-PH02 Series A and 1761-CBL-AH02 Series A. When using a programming terminal such as the MicroView programming terminal, the compatible communication cables needed are 2707-NC8 Series B 2707-NC9 Series B 2707-NC10 Series B and 2707-NC11 Series B. These cables are used to download and upload programs, monitor and commission the controller.

The integrated memory of this controller amounts to 1KB memory capable of being downloaded with approximately 737 instructions and 437 data words. This controller is powered by an input voltage supply of 20.4-26.4V dc with nominal voltage rating of 24VDC. This controller has power dissipation of 5W and inrush Current of 30A for 4ms.

The Allen-Bradley 1761-L16BBB is a MicroLogix 1000 16-point DC controller with multiple inputs and outputs available. It has 10 24V DC inputs, 4 MOSFET sourcing outputs (with 3 amps current per controller), and 2 relay outputs (with 2 isolated relays per unit). This controller is capable of high-speed I/O, as it has a 6.6 kHz high-speed input available. This controller features LED indicators that you can use to monitor its current condition. LED indicators available for this controller are input, output, and status LEDs. It also has the Master Control Relay safety feature available.

The 1761-L16BBB controller also comes with a 1-K EEPROM memory and 2 communication ports, namely a DF1 port and an RS-232 port. It comes with a maximum of 40 timers and with a 2 ms typical response time for program scan time/Kword and 0.21 ms typical I/O scan time. It can mount on a DIN rail or a panel. This controller measures 4.72 x 1.57 x 3.15 inches.

This controller has a 24V DC sink/source power supply, input, and output power and makes use of an IP20 enclosure. It has a real input power of 5 W at 24V DC and a 1500 VAC isolation. Note that both the chassis ground and the 24V DC user supply are connected internally.

The minimum power cycle of this controller is 50,000. When mounted horizontally, it has an operating temperature of 0 to 55 Degrees Celsius and when mounted vertically, its operating temperature is 0 to 40 Degrees Celsius. It also has a non-condensing relative humidity of 5 to 95% and an ESD immunity of 8 kV air (IEC801-2). The 1761-L16BBB controller has a radiated RFI suppression of 10V/m, 27 to 1000 MHz, 3V/m, 87 to 108 MHz, 174 to 230 MHz, And 470 to 790 MHz (IEC801-3). It also has an operating shock of 10 g and a non-operating shock of 20 g, as well as an operating vibration of 2.5 g and a non-operating vibration of 5 g.
