Motor control and I/O board (RMIO)
What this chapter contains
This chapter shows
• external control connections to the RMIO board for the ACQ800 Pump Control
Program
• specifications of the inputs and outputs of the board.
To which products this chapter applies
This chapter applies to ACQ800 units which employ the RMIO-01 board (revision J
or later) or the RMIO-02 board (revision H or later).
Note on cabinet-installed ACQ800 drives
The terminals of the RMIO board are optionally wired to terminal block X2. The
connections shown below apply also to terminal block X2 (the markings are identical
to the ones on the RMIO board).
Terminals of X2 accept cables from 0.5 to 4.0 mm 2 (22 to 12 AWG). The tightening
torque for screw terminals is 0.4 to 0.8 Nm (0.3 to 0.6 lb-ft). For disconnecting wires
from spring terminals, use a screwdriver with a blade thickness of 0.6 mm (0.024 in)
and width of 3.5 mm (0.138 in), e.g. Phoenix Contact SZF 1-0,6X3,5.
Note on terminal labelling
Optional modules (type Rxxx) may have terminal designations that coincide with
those on the RMIO board.
