Piping Port Indication; Operation Timing And Output - SMC Networks VR51 Series Operation Manual

8. Piping Port Indication

Each value in parentheses indicates a port number for VR51-C07
EXH. PORT：R(4)
OUT PORT：A(2)

9. Operation Timing and Output

If the delay between the two input air signals is 0.5 seconds or longer, there will be no output.
The time delay with which output from VR51 is possible differs depending on the operating pressure.
The higher the operating pressure, the shorter the time delay, and vice versa .
The time delay with which output is possible is shown below. As it differs depending on the piping
conditions and the device to be connected, use this graph only as a guide.
