Selecting Input Type (
Input
)
Seven input types may be set. See Rate Input specifications on page 9 for electrical
specifications of the inputs.
The following input types may be selected:
Active (
activ
)
External power supply driven pulse inputs
NPN (
NPN
)
Internal pull-up resistor on S+ for NPN inputs
PNP (
PNP
)
Internal pull-down resistor on S+ for PNP inputs
Reed (
reed
)
Internal pull-up resistor on S+ for switch inputs
Coil (
COIL
)
Magnetic coil flowmeter inputs (input selector switch must be set to mV)
Isolated active input (
iso
)
External power supply driven isolated pulse inputs (input selector switch must be
set to ISO)
Active with low threshold (
acTLO
)
External power supply driven pulse inputs with a low threshold
NPN with low threshold (
NPNLO
)
Internal 3 V pull-up resistor on S+ for NPN inputs with a low threshold
PNP with low threshold (
PNPLO
)
Internal pull-down resistor on S+ for PNP inputs with a low threshold
Input Level Selection Switch
In addition to programming the
Input
parameter, the input selector switch shown
below must also be set. Input voltage level selections include mV, V and isolated
voltage level inputs.
