Allen-Bradley 1753-L32BBBP-8A GuardPLC Controller

The Allen-Bradley 1753-L32BBBP-8A is a GuardPLC controller and a programmable electronic system with up to 24 digital inputs, two counters, eight digital outputs, four connections, and eight analog inputs designed for GuardPLC Ethernet communication. The status of these 24 digital inputs is shown through the status indicators when the controller is put in a RUN mode. The LS+ voltage source provides 24 Volts DC for up to eight dry contact inputs. The GuardPLC 1800 controllers are available in three groups. Based on IEC 61131-3, the OS is loaded in the central unit of 1753-L32BBBP-8A GuardPLC controller and need to be used in the valid, TUV-certified form required for the safety-related applications.

The line break and short-circuit monitoring system, such as the E-stop inputs, can’t be configured for the 1753-L32BBBP-8A GuardPLC 1800 controller, because the 24 discrete inputs include analog inputs with a one-bit resolution. This GuardPLC controller offers high-speed counter connections. 1753-L32BBBP-8A have two independent high-speed counters of 24-bit. They are configured for 5 or 24 Volts DC, with a maximum input frequency of 100 KHz. These counters can be used or as a decoder or a counter for the 3-bit Gray Code inputs. When used as a counter, the counter input is input A, the counter direction input is input B, and input Z is used to reset the system to default.
