What you mentioned should be HIMA Z7127. It is a component module of the H41q and H51q system series of HIMA company. The following is its relevant information: Function: System control function: As a part of the programmable logic controller (PLC), it participates in the control logic operation of the entire system. It receives input signals from field devices, such as digital and analog quantities, and processes these signals according to preset programs and algorithms. Then, it outputs control signals to actuators to achieve precise control of industrial processes, such as controlling the start and stop of motors and the opening degree of valves. Communication function: Communicate with other modules in the HIMA system, such as the central processing unit, input/output modules, and communication modules, to achieve data transmission and exchange. Send the processed data to other modules through the system bus and simultaneously receive information from other modules to ensure the coordinated operation of the entire system. Characteristic: High reliability: Adopt redundant design and can be used as a single-channel or dual-channel (redundant) device. It has the same modules at the central equipment and input/output levels. When a module fails, the redundant module can automatically take over to ensure the continuity and stability of the system. It complies with the SIL 3 safety-related application standard (according to IEC 61508) and has a high safety integrity level. It can be used in industrial scenarios with extremely high safety requirements.</
