2.7 Sensor Adapters (option)
A maximum of eight MC-3000S can be connected to a sensor network (for the redun-
dant connection: 16). The MC-3000S (serial input/output, IEC61162-2/1, 4ch) can
connect a maximum of 10 sensor adapters, using the MC1.5-W cables. The maximum
number of MC-3010A units is five.
When fabricating the MC1.5-W cables, use the lot terminal (ferrule type, supplied) to
maintain performance. Use the ferrule-type terminals (supplied) to connect the cables
to the terminals in the sensor adapters. This connection requires a crimping tool
(CRIMPFOX10S, option). For the relations between the connectors and rod terminals,
see page AP-2. Also, the stickers attached on the reverse side of the covers show the
detailed connections.
Attach the cables to the applicable pins.
Note 1: Use the MC1.5-W cable between the sensor adapters.
Note 2: The total length of the MC1.5-W cables must be less than 6 m to prevent mal-
function.
