3-2 I/O Configuration and Wiring Revised Mar-2011
3.2 Process I/O Board
ControlWave ExpressPAC may include an optional Process I/O board.
The Process I/O board stands vertically on edge against the inner left
side of the enclosure and mounts to the CPU/System Controller board
using six nylon mounting posts.
To configure the Process I/O board, you need to set some switches and
jumpers. See Figure 3-1 for the location of the switches and jumpers.
3.2.1 Setting Jumpers on the Process I/O Board
The Process I/O board has several jumpers.
 JP1: AO output source (1-5V or 4-20mA):
o
1-to-2 Installed = 4-20mA analog output
o
2-to-3 Installed = 1-5V analog output
 JP3: AO power source:
o
1-to-2 Installed = system power
o
2-to-3 Installed = external power (+11 to +30 Vdc)
 JP4: AI field power configuration:
o
1-to-2 Installed = external 24Vdc power
o
2-to-3 Installed = bulk input supply (system power)
 JP5: AI1 input type (1-5V or 4-20mA)
o
1-to-2 Installed = 4-20mA analog input
o
2-to-3 Installed = 1-5V analog input
 JP6: AI2 input type (1-5V or 4-20mA)
o
1-to-2 Installed = 4-20mA analog input
o
2-to-3 Installed = 1-5V analog input
 JP7: AI3 input type (1-5V or 4-20mA)
o
1-to-2 Installed = 4-20mA analog input
o
2-to-3 Installed = 1-5V analog input
3.2.2 Setting DIP Switches on the Process I/O Board
The Process I/O board includes a single switch bank (SW1) to configure
the frequency for the high speed counters (HSC), the source current for
discrete inputs/counters, and the analog output.
Table 3-2. Process I/O Board Switch SW1
SW1 Function Mode
SW1-1
Frequency for High Speed Counter1 (HSC1)
OFF = 10 kHz (high speed)
ON = 300 Hz (low speed)
SW1-2 Frequency for High Speed Counter2 (HSC2) OFF = 10 kHz (high speed)
ON = 300 Hz (low speed)
