7.3 Input/Output
Enables analog and digital inputs / outputs and relays to be configured.
Analog Inputs
Analog Input 1 (4)*
Input Type Input types comprise:
Millivolts, Milliamps, Volts, Resistance (Ohms), RTD, Thermocouple, Digital
volt-free, 24V Digital, Freq. Input, Pulse Input
.
Additional Input Type comments:
Digital Volt Free
Acts as a digital input.
Freq. Input
Sets the maximum frequency and equivalent flow rate in the engineering range 0 to 6 KHz.
(A frequency of 0.01 to 6 KHz can be used to create an analog value.)
Pulse Input
This parameter counts pulses and is recommended only for use with electromagnetic
flowmeters.
*Analog Inputs 2 to 4: Freq Input, Pulse Input and Resistance not available. A Thermocouple input type can be set only if the first input is set to
Thermocouple.
