The 1761-L32BWB by Allen-Bradley has 32 digital I/O and a 24 Volt DC input type. This hardware has a relay output type and a 24 Volt DC power supply. Specifications for this hardware include an operating temperature between 0 and 55 degrees Celsius for horizontal mounting and 0 to 40 degrees Celsius for vertical mounting. Storage temperature is between -40 and 85 degrees Celsius and its operating humidity is 5 to 95% (non-condensing). General specifications for this hardware include 1 K of EEPROM memory and a 50,000 power cycle minimum. Terminal screw torque for this controller is 0.9 Newton-Meters (maximum) and the electrostatic discharge rating is EN 61000-2 at 8,000 Volts. This device has an isolation voltage of 1,500 Volts AC. Analog input specifications include a voltage input range between -10.5 and 10.5 Volts DC and a current input range between -21 and 21 MilliAmps. Data type with regard to analog input is 16-bit signed integer and non-linearity is 0.002%. For analog output specifications, voltage output range is 0 to 10 Volts DC and current output range is 4 to 20 MilliAmps. Data type is 16-bit signed integer and non-linearity is 0.02%. Step response is 2.5 milliseconds at 95% and both voltage and current output miswiring can withstand short circuit.

For installation of this controller onto a DIN rail, the manufacturer lists a series of recommended steps to follow: first, mount the din rail leaving enough required room for the controller, as recommended by the manufacturer. Next, secure the top slot on the controller over the DIN rail. Once this has been done, snap the controller into place while pressing the controller against the DIN rail. It should be noted that the manufacturer recommends leaving the protective film on the device until installation has been completed.VIIIVThe 1761-L32BWB by Allen-Bradley and Rockwell Automation is a MicroLogix 1000-Series Programmable Logic Controller (PLC).
