About 1761-L16BBB

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.
