Overview of Removable Box
An NSH5-AL001 Removable Box can be connected between the NSH5-
SQG10B-V2 PT (the model with a gray stop switch) and the host PLC to
enable easily attaching and detaching the NSH5 without affecting the wiring to
the PLC or safety circuits. The Removable Box also enables converting
between RS-232C and RS-422A.
The Removable Box is equipped with a rotary switch to set the station number
used to identify the Removable Box and a DIP switch for setting RS-422A
communications conditions.
System Configuration
The NSH5 PT is connected to a PLC through the Removable Box. Always use
an NSH5-232CN-3M/10M Special Cable to connect the NSH5 PT to the
Removable Box.
Note
(1) Always turn OFF the key switch before connecting or disconnecting the
Cable using the Removable Box.
(2) Always use the Removable Box connected to the NSH5-SQG10B-V2 PT
(the model with a gray emergency switch).
