CI-ControlWave Express Introduction / 1-13
• Two Non-Isolated Internally-Sourced High Speed Counter Inputs (or DI operation
supported)
• Three Non-Isolated Single-Ended 1-5V or 4 to 20mA Analog Inputs (Optional)
• One Non-Isolated Externally-Powered 1-5V or 4 to 20mA Analog Output (Optional)
1.3.3.1 Process I/O Board Configuration Jumpers and Switch SW1
ControlWave Express I/O Boards are provided with 6 User Configuration Jumpers and one
4-position DIP-Switch (SW1) that function as follows:
• JP1 - AO Output Source (1-5V or 4-20mA)
1 to 2 = 4-20mA Analog Output
2 to 3 = 1-5V Analog Output
• JP3 - AO Power Source
1 to 2 = System Power
2 to 3 = External Power (+11 to +30 Vdc)
• JP4 - AI Field Power Configuration
1 to 2 = External Power
2 to 3 = System Power
• JP5 - AI1 Input Type (1-5V or 4-20mA)
1 to 2 = 4-20mA Analog Input
2 to 3 = 1-5V Analog Input
• JP6 - AI2 Input Type (1-5V or 4-20mA)
1 to 2 = 4-20mA Analog Input
2 to 3 = 1-5V Analog Input
• JP7 - AI3 Input Type (1-5V or 4-20mA)
1 to 2 = 4-20mA Analog Input
2 to 3 = 1-5V Analog Input
• SW1 - HSC high/low frequency select, DI/HSC Source Current & AO Configuration
SW1-1: HSC1 – OFF= 10 kHz (high speed), ON = 300 Hz (low speed)
SW1-2: HSC2 – OFF= 10 kHz (high speed), ON = 300 Hz (low speed)
SW1-3: DI/HSC 2mA Source Current – OFF = Disabled, ON = Enabled
SW1-4: AO Configuration – OFF = Current, ON = Voltage
