Three input/output channels (A, B, and C) that can be configured from the fol-
lowing choices:
(4)
• One or two active 4–20 mA outputs, not intrinsically safe:
- Isolated to ±50 VDC from all other outputs and earth ground
- Maximum load limits of mA1: 820 ohms; of mA2: 420 ohms
- 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
Version 03.02.2003
• One or two active or passive frequency/pulse outputs, not intrinsically safe
- Can report mass flow or volume flow, which can be used to indicate
flow rate or total
- If configured as a dual pulse output, the channels are electrically isola-
ted but not independent
(5)
- Scalable to 10,000 Hz
- If active, output voltages is +15 VDC ±3% with a 2.2 kohm internal pull-
up resistor
- If passive, output voltage is 30 VDC maximum, 24 VDC typical, sinking
up to 500 mA at 30 VDC
- Output is linear with flow rate to 12,500 Hz
• One or two active or passive discrete outputs, not intrinsically safe:
- Can report five discrete events, flow switch, forward/reverse flow, cali-
bration in progress, or fault
- If active, output voltage is +15 VDC ±3% with a 2.2 kohm internal pull-
up resistor
- If passive, output voltage is 30 VDC maximum, 24 VDC typical, sinking
up to 500 mA at 30 VDC

One Foundation fieldbus H1 or PROFIBUS-PA output:
• FOUNDATION fieldbus and PROFIBUS-PA wiring is intrinsically safe with an
intrinsically safe power supply
• The transmitter fieldbus circuit is passive, and draws power from the field-
bus segment. Current draw from the fieldbus segment is 13 mA
• Manchester-encoded digital signal conforms to IEC 61158-2
✓
One FOUNDATION fieldbus H1 output:
• FOUNDATION fieldbus wiring is non-incendive
• The transmitter fieldbus circuit is passive, and draws power from the field-
bus segment. Current draw from the fieldbus segment is 13 mA
• Manchester-encoded digital signal conforms to IEC 61158-2
