About
The 1761-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. High-speed I/O is supported by the single 6.6-kilohertz input. 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 a 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 an 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.
