4) The following diagram shows an example for terminal connections.
Note: (1) All the channels of the output circuit are isolated each other.
(2) Recommended Cables
Use shielded twisted-pair wires of 1.3 mm
2
(AWG16) to 0.5 mm
2
(AWG20) to
connect to the terminal block.
(3) One-point Shield Connection
As a rule, connect the shield at one point on the load side. However, better out-
put characteristics may be obtained by connecting it at one point on the Module
side rather than on the load side, so consider which way is better depending on
the actual situation. An incorrect connection will make input signal unstable and
cause malfunction.
(4) Grounding the Module
The “Not connected” terminals of the Module are not connected inside the Mod-
ule. Use them as relay terminals, if necessary.
(5) Crimp Terminals
Use M3 terminals for crimping to the terminal block.
(6) Unconnected Terminals
Terminals 1 to 5, 7, 9 to 13, 15 and 17 to 20 are not connected.
