Outputs
Analog
Standard: Three (3) 4-20 mA*, 0-1kHz, or 0-10 kHz pulse/frequency
4-20 mA outputs are user assignable to flow rate, temperature
and/or if so equipped, pressure; outputs are user programmable to
full flow range or subsets of full flow range; pulse/frequency output
is user selectable as pulse for external counter/flow totalizer, or as
0-1 kHz or 0-10 kHz frequency representing flow rate
HART (comes standard with analog outputs, V7 compliant
* Outputs are isolated and have fault indication per NAMUR NE43
guidelines, user selectable for high (>21.0 mA) or low (<3.6 mA)
Digital
Standard: USB, Ethernet - Service and Configuration Ports Only
Optional: F
oundation Fieldbus H1, PROFIBUS PA or Modbus RS-485
FF Physical Parameters
Device Capacitance - Ci (in nF) = 0
Device Inductance - Li (in mH) = 1.01
Maximum Network Input Voltage - Ui (in V) = 32
Maximum Network Input Current - li (in mA) = 13
Auxiliary Inputs
One 4-20 mA input channel; used for FCI administered special
configurations to allow ST100 Series to accept inputs from external
devices such as gas analyzers, gas composition or pressure sensors
