Preventa safety controllers

Type:  Controller
Description:  Safety controllers XPS MC XXX are designed to meet the requirements of safety applications requiring conformity to category 4 of standard EN 954-1. They are available in 2 versions: - XPS MC16X with 16 inputs and 8 independent safety outputs, - XPS MC32X with 32 inputs and 8 independent safety outputs. Safety controllers devices are based on redundant microprocessor technology, and therefore benefit from more sophisticated functionality: flexibility of choice of safety function and more accurate diagnostics represent some of the advantages from which machine manufacturers and users can benefit by integrating these innovative solutions.
Connectivity:  Modbus
Features:  Safety controllers XPS MC XXX are designed to meet the requirements of safety applications requiring conformity to category 4 of standard EN 954-1. The safety inputs are supplied by the various control outputs, in such a manner so as to monitor for short-circuits between the inputs, short-circuits between each input and earth or the presence of residual voltages. The controller, assisted by the control outputs, continuously tests all the connected inputs. As soon as an error is detected on an input, all the outputs associated with this input are disconnected. Safety outputs associated with other inputs remain active. - The 10 safety outputs comprise 4 contact guided relay outputs and 6 solid-state outputs. Safety controllers XPS MC incorporate a Modbus communication interface for configuration and diagnostics. The Modbus interface enables the controller to be connected to a PC, PLC or an operator dialogue terminal.
