The Allen-Bradley 1753-L32BBBM-8A controller is an industrial controller that is part of the Allen-Bradley GuardPLC series and that is meant to be used as part of a complete GuardPLC system. It comes with 24 digital inputs that are not electrically isolated and with 8 digital outputs that are also not electrically isolated. The 1753-L32BBBM-8A controller also has 8 analog inputs that are unipolar and not electrically isolated. The operating temperature range for this controller is from 32 to 140 degrees Fahrenheit and its storage temperature range is from -40 to 185 degrees Fahrenheit. The 1753-L32BBBM-8A controller has a relatively low protection rating of IP 20.
The Allen-Bradley 1753-L32BBBM-8A is a Safety Controller from GuardPLC 1800 series. This controller has the most I/O points among GuardPLC controllers. It is equipped with 32 I/O points (24 inputs and 8 outputs, none of which are electrically isolated). Output channels 4 and 8 can withstand 1 Amp of current at 60 degrees Celsius and the other channels are 0.5 Amps rated. The 1753-L32BBBM-8A controller also has 2 (not electrically isolated) high-speed counters with a 24-bit resolution. There are 250 KB of user program memory and 250 KB of application data memory installed to support microprocessor in fault processing. This device will detect a fault in their controlling system behavior and put all affected inputs and outputs from the faulty module to the safety state.
The special feature of the 1753-L32BBBM-8A GuardPLC 1800 controller is the Modbus Communication option. Users can exchange signal values and other data with another industrial automation devices by using this communication protocol. The Allen-Bradley 1753-L32BBBM-8A is designed to be connected to a 24 Volts DC/8 Amps power source. It is shipped in an IP20 protected housing with dimensions of 114 millimeters (4.49 inches) x 257 millimeters (10.1 inches) x 80 millimeters (3.15 inches) including the shield plate. Its weight is approximated at 2.6 pounds (1.2 kilograms). Do not use this device outside of the 0 to 60 degrees Celsius (32 to 140 degrees Fahrenheit) temperature range. The controller has passed rigorous tests to be certified by CE, C-Tick, and c-UL-us standards.
