CSRME is designed based on the standard GB 27607, and it ensures that the safety of tool machine control system meets the requirements of GB 27607 by means of monitoring machine tool safety-related device. The safety of this product meets the requirements of ISO 13849-1 (PLe) and IEC 61508 (SIL3). With rich interfaces, CSRME has limited programmable function. It can simultaneously replace many different types of safety control modules or safety PLCs, thus greatly simplifying the safety design of machine control systems and reducing cost.
