3-2 I/O Configuration and Wiring Revised Feb-2013

3.2 Process I/O Board

ControlWave GFC Plus 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 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 Module 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)
