About

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 10 DC point inputs with a 6-point relay output. Its input voltage ranges between 14 and 30V DC and it has 24V DC 8.0A ON voltage/current. The 1761-L16BWB’s analog input voltage/current ranges between -10.5 and +10.5V DC/-21 to +21 mA and it has a voltage impedance of 210 Kilo Ohms, a current impedance of 16 Ohms, and an input resolution of 16 bits at < 0.002% non-linearity. Additionally, it offers an input current protection at ±50 mA and voltage protection at 24V DC. The analog input’s isolation voltage is 30V tested for 1s at 500V between the input and output and Field wiring to the Logic Isolation. Its 6-point relay outputs have a 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 >1kΩ voltage impedance and a 0-500Ω 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.
