LT Series Remote I/O (Flex Network)
24
See our Web site for LT Series system application examples.
* Use special cables capable of stable high-speed communications when connecting Flex Network units.
6Mbps/12Mbps high-speed remote I/O lets you use remote equipment without remote equipment performance.
Connect up to 1008 I/O points and attain communications lag time of only 0.94ms (at 512 points/12Mbps).
Extensions up to 400m (with 6Mbps x 2 channels).
* 256-point: 944µsec/472µsec response speed at 6Mbps/12Mbps communications speed.
*1 The FN-PC unit’s live line is not isolated. If it is connected to a non-isolated servo driver, be
sure to connect the signal ground (5G) to prevent over-current damage.
*2 For motor driver connection details, refer to User's manual.
*3 The FN-HC unit’s input line is not isolated. When connecting this unit to a line driver
that is not isolated, be sure to connect the signal ground (SG) terminal.
*4 The Input Common (I-COM) shown here is connected to a Sink Output type. (The
dotted line shows the connection with a Source Output type.)
