4.4 Wiring the Connector Type I/O Units
RT-2 Relay Terminal
For 64-point type output unit (FP2−Y64T), you can connect four sets of the RT-2 relay
terminals with 16 outputs by using two-branch type cable.
For 32−point type output unit (FP2−Y32T) and output connector side of I/O mixed unit
(FP2−XY64D2T, FP2−XY64D7T), you can connect two sets of the RT-2 relay terminals
with 16 outputs by using two-branch type cable.
For connecting the terminal to the terminal block, use M3-sized pressure connection
terminals.

put units and I/O mixed units
Two-branch type cable for relay terminal (40 pins − 40 pins × 2)
RT-2 relay terminal (16 outputs)
(AY232502 or AY232522)
The relay terminal that is connected with the
shorter cable is the lower I/O number.
Note
24V DC should be supplied between the (+) and (−) terminals of
the relay terminal. Power is supplied to drive the relays of the ter-
minal itself. The I/O power supply supplied to the units and the
power supply supplied to the RT-2 relay terminals are the same
power supply.
