Selecting Input Type (Input)
Seven input types may be set. See
Rate Input specifications on page 3 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.
INPUT LEVEL
mV V ISO
See
Rate Input specifications on page 3 for electrical specifications of the inputs.
