1761-L10BWB

The 1761-L10BWB is a MicroLogix 1000 Programmable Logic Controller (PLC). This controller is manufactured by Allen-Bradley that is specifically designed for use in micro and small automation applications. It can be used in both machine and process automation and comes in a small, compact form factor intended for DIN rail or panel mounting. The 1761-L10BWB features a total of Ten (10) embedded discrete inputs and discrete outputs. Specifically, Six (6) 24 VDC inputs, and Four (4) relay outputs. The discrete inputs accept an input voltage range of 14-30 VDC with nominal signal input of 24 VDC. The minimum On signal input is 2.5 mA at 14 VDC 8.0 mA at 24 VDC and a maximum of 12.0 mA at 30 VDC. The relay output channels are operable at voltages of 120 / 240 VAC and continuous current of 2.5 Amperes, 24 VDC, and continuous current of 1.0 Ampere and 125 VDC at a continuous current of 2.0 Amperes. The 1761-L10BWB operates at an input supply voltage of 204 - 26.4 VDC with power supply usage of 10 Watts. The integrated communication interface is a single RS232 communication that supports the DF1 protocol designed for the point-to-point connection of the programming workstation, Human Machine Interface (HMI), and programming terminal. The available memory installed to the 1791-L10BWB amounts to a total of 1KB which is internally allocated for 737 instruction words and 437 data words.

The the1761-L10BWB programmable controller is one of Allen-Bradley’s MicroLogix 1000 modules. This controller has 10 inputs and outputs, specifically 6 24-Volt DC inputs and 4 relay outputs. It also comes with an RS-232 and a DF1 communication port. This controller has a master control relay safety feature, which allows the controller to shut down in emergencies. This controller’s power supply voltage is 20.4 to 26.4 Volts DC and power consumption of 5 Watts at 24 Volts DC. It also has a maximum power supply inrush current of 30 Amps for 4 milliseconds and isolation of 1500 Volts AC. Note that the user supply 24 Volts DC IN ground and chassis ground are already internally connected. The controller can mount on either a DIN rail or a panel. The 1761-L10BWB’s operating temperature range is from 32 to 131 degrees Fahrenheit when mounted horizontally and from 32 to 113 degrees Fahrenheit when mounted vertically. Its storage temperature range is from -40 to 185 degrees Fahrenheit and its non-condensing relative humidity is 5 to 95%. Its operating vibration is 2.5 g while its non-operating vibration is 5 g. It has an operating and non-operating shock of 10 g and 20 g respectively. The 1761-L10BWB measures 4.72 x 1.57 x 3.15 inches. It features diagnostic LEDs for status, input, and output and a built-in 1 K EEPROM memory that can hold up to 737 instruction words and 437 data words. It has up to 40 available timers, a program scan time or Kword of 2 milliseconds, and an I/O scan time of 0.21 milliseconds. This controller also has a minimum of 50,000 power cycles.
