Input/output signals

Model 2400S Analog

Channel A One active or passive 4–20 mA output

• Not intrinsically safe

• Isolated to ±50 VDC from all other outputs and earth ground

• Maximum load limit: 820 ohms

• External (passive) power: 12 to 30 VDC, 24 VDC typical

• Can report mass flow, volume flow, density, temperature, or drive gain

• Output is linear with process from 3.8 to 20.5 mA, per NAMUR NE43 (February 2003)

Channel B (configurable) One active or passive frequency/pulse output

• Not intrinsically safe

• Can report mass flow or volume flow, which can be used to indicate flow rate or total

• Scalable to 10,000 Hz

•Power:

- Internal (active): +24 VDC ±3% with a 2.2 kohm internal pull-up resistor

- External (passive): +30 VDC maximum, +24 VDC typical

• Output is linear with flow rate to 12,500 Hz

One active or passive discrete output

• Not intrinsically safe

• Can report five discrete events, flow switch, forward/reverse flow, calibration in progress,

or fault

•Power:

- Internal (active): +24 VDC ±3% with a 2.2 kohm internal pull-up resistor

- External (passive): +30 VDC maximum, +24 VDC typical

• Maximum sink capability: 500 mA

One active or passive discrete input

• Not intrinsically safe

•Power:

- Internal (active): +24 VDC, 10 mA maximum source current

- External (passive): +3 to 30 VDC maximum

• Can reset all totals, reset mass total, reset volume total, start/stop totals, or start sensor

zero
