About 1761-L16BBB

The 1761-L16BBB is a MicroLogix 1000 compact controller. It is powered by a DC supply rated 24VDC. This controller has a compact form with embedded 16 I/O points. The controller has Ten (10) 24V DC inputs, 4 MOSFET outputs in sourcing configuration and 2 relay outputs. The 1761-L16BBB supports high-speed I/O with switching frequency of 6.6 kHz. The built-in LED indicators provide quick diagnostic view of the controller’s state as well as the energized input and output channel. The 1761-L16BBB is compliant with EMC directives EN 50081-2 EMC – Generic Emission Standard, Part 2 – Industrial Environment and EN 50082-2 EMC – Generic Immunity Standard, Part 2 – Industrial Environment. Even with programmable logic controllers, it is still advisable to use a hardwired system to handle emergency or process abnormalities. The 1761-L16BBB controller comes with a 1-K EEPROM memory with RS232 communication port compatible with DF1 protocol. DF1 protocol supports half and full duplex transfer with multiple Baud Rate selection. This MicroLogix 1000 controller has physical dimensions of 4.72 x 1.57 x 3.15 inches. It can be mounted on a DIN rail or a flat mounting surface using mounting screws. The controller supports horizontal and vertical mounting. In vertical mounting, take caution with hot air rising up to the other parts of the controller. In this mounting arrangement, one part of the controller will have the highest temperature. Install a correct ventilation to avoid improper flow of warm air. The control is configured using RSLogix500 software. RSLogix500 is a Ladder programming software that uses data files to access input, output and internal addresses.
