I am desigining a security system for a belt conveyor, and I'm using two-way pull cords. These pull cords will be connecting in 24Vcc. The signal will be sent to a box where I'll make series connection among them, and after that, the signal will be send for a PLC. There will be a security relay in this path, and I wanna know the impedance of this relay can to affect my signal, and how can I design this? If you have a reference to tell me, or explain how to do this calculation, I'll e very grateful.
