1 year Warranty Included



The 1761-L32BWB MicroLogix 1000 Programmable Controller by Allen-Bradley is a 32 I/O point controller with 20 DC inputs, 12 relay outputs, and an overall DC power supply voltage of 24 Volts DC. It has an input voltage range between 14 and 30 Volts DC and an ON rating of 24 Volts DC and 8.0 mA. Its inputs have 5V OFF voltage with a 1.5mA maximum OFF current and a nominal impedance of 3 Kilo-ohms. It has an Analog input with a -10.5 to 10.5 Volt DC voltage range and -21 to 21 mA current range. The Analog input has a voltage input impedance of 210KΩ with a 16Ω current and 16-bit input resolution at < 0.002% non-linearity. The 1761-L32BWB also has a ±0.7% overall accuracy and a ±0.176% accuracy drift with 24 a Volt DC input voltage overprotection.

The analog input has ±50 mA current over protection and an isolation voltage of 30 Volts tested at 500 Volts for 1 second between the input-to-output isolation and Field wiring-to-Logic Isolation. It has a Relay output with a minimum current load of 10.0 mA, and an OFF to ON response time of 10 milliseconds with a 10 millisecond ON to OFF response time. Its relay output has a contact rating of 2.0A per point, with a 1.2A Make Ampere and a Make power of 28VA. The 1761-L32BWB has an analog output with a voltage range between 0 and 10 Volts DC and a 4-20 mA current output range. It has a non-linearity value of 0.02% and a response time of 2.5 milliseconds. It has an output voltage impedance greater than 1kΩ, and a current impedance between 0 and 500Ω. The analog output has an accuracy of ±1.0% at 0 to 55 degrees Celsius and an overall drift of ±0.28% at the same temperature with an isolation voltage of 30 Volts tested at 500 Volts for 1 second between field wiring and Logic isolation. The 1761-L32BWB has dimensions of 200 x 40 x 80 millimeters (7.87 x 1.57 x 3.15 inches).
