Take a look at the TV monitoring connector. It's not as complicated as you think: boards, mounts, screw heads, capacitors, inductors, matchers, resistors, and RF plugs. Plus plastic shell. It stands to reason that these components are not easily damaged. The problem is that the capacitor at the signal output is not soldered to the entire board. Instead, one is welded to the plate. The other end is bent and connected directly to the RF core wire (left). Since the user repeatedly plugs in the TV set, the F head can be rotated again, and the cable is pulled by gravity, and the original design is not perfect. After the cable is connected, the arm is relatively long and there is no stable support point. It is inevitable that a broken solder joint will occur between the soldering leg of the plug and the circuit board. No wonder there are new heads. The user is broken a few times and it is broken! Connecting repair welding is not difficult. The trouble is in this "one-off" product designed for non-removable molded cases. The method of transformation, intercepting the appropriate length of the paper clip for a short bend adjustment. Elbow on the tin. Then the core wire capacitor is completely welded, and the hole is exactly the same as the diameter of the pin. Solder the needle straight end, the elbow welding signal is at the end of the core wire, and the welding should be firm (right). Solder the capacitor on the back side and connect it to the right end of the pin. Cut the copper foil with a knife between the two feet, close the molded case, and bond it with 502 glue.

CSRME safety controller is developed for standard GB27607. By monitoring machine tool safety related equipment, the security of machine control system can meet the requirements of GB27607, and its security meets the requirements of ISO13849-1 (PLe) and IEC61508 (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.
