Model 1700 and 2700 Transmitters
Specifications
One or two frequency/pulse outputs:
• Channels B and C are configurable as frequency/pulse outputs
• If both are configured for frequency/pulse:
- The channels function as a dual-pulse output which reports a single process variable.
Channels are electrically isolated but not independent
- Output on channel C can be phase-shifted 0, 90, or 180 degrees from the output on channel
B, or the dual-pulse output can be set to quadrature mode
• Not intrinsically safe
• Configurable for internal or external power (active or passive):
- If internally powered, output voltage is 15 VDC ±3%, internal 2.2 kohm pull-up
- If externally powered, output voltage is 3–30 VDC maximum, sinking up to 500 mA at
30 VDC maximum
• Scalable to 10,000 Hz
• Can report mass flow rate or volume flow rate, which can be used to indicate flow rate or total
flow
• Linear with flow rate to 12,500 Hz
• Configurable polarity: active high or active low
One or two discrete outputs:
• Channels B and C are configurable as discrete outputs
• Can report event 1, event 2, event 1 & 2, flow direction, flow switch, calibration in progress, or
fault
• Maximum sink capability: 500 mA
• Configurable for internal or external power (active or passive):
- If internally powered, output voltage is 15 VDC ±3%, internal 2.2 kohm pull-up
- If externally powered, output voltage is 3–30 VDC maximum, sinking up to 500 mA at
30 VDC maximum
• Configurable polarity: active high or active low
One discrete input:
• Channel C is configurable as a discrete input
• Not intrinsically safe
• Configurable for internal or external power:
- Internal power: 15 VDC, 7 mA maximum source current
- External power: 3–30 VDC maximum
• Can be used to start flowmeter zeroing procedure, reset mass total, reset volume total, reset
corrected volume total, or reset all totals
