Appendix 3 Using NS-AL002 Converters
A-3-2 Mounting and Removing
Connect the NS-AL002 directly to port A or port B of the PT. Two NS-AL002 Adapters
cannot be connected to ports A and B simultaneously.
Mount the Adapter by tightening and securing the mounting screws on both of the D-Sub
connectors. The correct tightening torque is 0.3 N
•m. The correct tightening torque for the
terminal block is 0.5 N
•m.
To remove the Adapter, loosen the screws and pull out the Adapter.
Note
• Always turn OFF the power to the PT before removing the Adapter.
• Do not touch the surface or the mounted parts of the Board with bare hands.
Always discharge any static electricity from your body before handling the Board.
• Mount to the PT after securely connecting the cable to the terminal block.
Be sure to tighten the mounting screws on both of the D-Sub connectors. If the screws
are loose, the FG terminals of the PT and NS-AL002 will not be connected.
A-3-3 Specifications
The following table shows the general specifications and communications specifications of
the Adapter.

Reference
NS-series RS-485 (two-wire) communications are used to connect to an OMRON
Temperature Controller. The NS-AL002 cannot be used with the NT-series PTs or
PLCs.
● Communications Specifications
• RS-422A Interface
Item Specifications

Transmission distance 500 m total length (See note 1.)
Terminal block format 8-terminal terminal block, M3.0
Insulation No insulation (See note 2.)
Note 1: This specification is for a configuration in which all the Adapters connected on the same
transmission path are NT-AL002 Link Adapters. If a CJ1W-CIF11 Conversion Adapter is
used, the total length is 50 m.
Note 2: The RS-422A and RS-232C are not insulated.
