Can a single sensor signal be split and inputted into two different devices?

Yes, the LD Series can be used as a signal splitter, supporting configurations like 1-input to 2-outputs or 3-outputs. For example, you can easily set up a system to send a single sensor signal to both a PLC and a monitor output simultaneously.

Is it possible to customize or change to a specific termination resistance value?

Yes. COCORESEARCH accommodates customizations starting from a single unit. We can modify specifications to match your specific environment, including selecting the presence or value of termination resistors, choosing input/output isolation, and changing the power supply voltage.
