PHD-11TC-11
RS232 input/RS232 output 1 input 1 output
Overview
Isolated safety barrier at detection end: PHD-11TC-11, communication signal input, single input and single output. The safety barrier can realize the bilateral communication of digital signals between RS232 interface in dangerous area and RS232 interface in safe area.
This product needs an external 20-35VDC power supply.
The product is equipped with signal status indicator (yellow)
* bus terminal power supply, please see appendix for details.
