1761-L16BWB

The 1761-L16BWB MicroLogix 1000 by Allen-Bradley is a programmable controller in the MicroLogix 1000 series with 16 I/O points, a 24V DC input signal, a relay output type, and a 24V DC power supply. It has Ten (10) DC inputs and Six (6) point relay output. Its input voltage ranges of 14 to 30V DC and it has 24V DC 8.0A ON voltage/current. It offers an input current protection at +/-50 mA and voltage protection at 24V DC. The relay outputs is rated for 10mA current load and about 10ms ON to OFF/OFF to ON response time. The relay circuit comes with a relay contact with a 2.0Amps per point current rating with a 1.2A Make current capacity and 28VA of Make power. The 1761-L16BWB has a 0-10V DC analog output range and a 4-20 mA current output. It uses a 16-bit signed integer control data and has 0.02% non-linearity and 2.5ms response time. The analog output has an overall accuracy of 0.2%, and a drift of +/-1.0% with 15-bit output resolution. It also has 1k Ohms voltage impedance and a 0-500 Ohms current impedance. The 1761-L16BWB has 1KB EEPROM which can store approximately 737 instruction words. It has an overall dimension of 7.87in x 1.57in x 3.15in.

The 1761-L16BWB is a Programmable Logic Controller (PLC) that is manufactured by Allen-Bradley. This product is a MicroLogix 1000 PLC, a compact controller that is primarily designed for use in small processes or applications that require migration from conventional hardwired control system to programmable, electronic based controlled system. This controller may specifically be used in Machine Control applications, Factory Floor automation and Process applications such as Water, Waste Water, Heating Ventilation and Air-Conditioning (HVAC) and other process areas.

This controller is provided with an RS232 interface that support Allen-Bradley’s DF1 protocol. This port uses a particular communication cable such as 1761-CBL-PM02, to enable upload, download, monitoring and commissioning. It also enables communication with Human Machine Interface (HMI), Supervisory Control and Data Acquisition (SCADA) and 3rd party electronic devices such as gateways and converters. The RS232 interface may also be configured for DH485 protocol and further enabled to connect to this network using an external Advanced Interface Converter (AIC) with part number 1761-NET-AIC.

It may also be programmed using the MicroLogix 1000 Hand-Held Programmer.

The 1761-L16BWB is equipped with an embedded Ten (10) discrete inputs and Six (6) relay outputs. It is powered by an external supply voltage of 24VDC. The inputs are rated for 24VDC signals while the relay outputs contacts are rated for 0-125VDC or 0-240VAC voltage ranges. The integrated memory of this controller amounts to1 K EEPROM, capable of storing approximately 737 instruction words: 437 data words.
