Connection Of Scan I/O Card - Mitsubishi Electric M70V Series Connection Manual

4.6 Connection of Scan I/O card

(1) External power supply (DCIN)
24VDC is required for the HR347/HR357 card operation. Prepare a stabilized power supply that satisfies the
following specifications.
Output: 24VDC±5%
Ripple: ±5％(P-P)
Rated output current: 2.5A
* The rated output current is the value when using 60mA × 32 points for the machine output.
Prepare a power supply that satisfies the 24VDC output's total output current and control current (0.5A).

(2) Connecting the remote I/O communication cable (RIO3A/B)
(a) Connection of the RIO3A connector
Connect the RIO3A to the RIO1 connector of the control unit or the RIO3 of the operation panel I/O unit.
(b) Connection of the RIO3B connector
Multiple remote I/O units can be used, as long as the total No. of occupied stations connected with serial links
is less than eight. (Refer to "Connection: Connection of Remote I/O Unit" for details.) HR357 occupies three
stations, so the remote I/O units can be connected to the RIO3B in combinations of 5 stations or less. Connect
a terminator to the RIO3B when it is not connected to any device.
