Terminals 3-6: System Power and Loop Power
12-24 VDC ±10% system power and current loop outputs.
Max. loop impedance:
50 Ω max. @ 12 V
325 Ω max. @ 18 V
600 Ω max. @ 24 V
Terminals 11-16: Flow sensor inputs
Terminals 7-10: Open-collector Outputs
Two transistor outputs, programmable (see CALIBRATE menu) as:
• High or Low setpoint with adjustable hysteresis.
• Pulse based on Volume.
• Frequency based on fl ow rate.
May be disabled (Off) if not used.
Terminals 1 and 2: AUXILIARY power
Used only if the fl ow sensor requires more
than 1.5 mA current. For Signet sensors this
is limited to the following products:
• 2000 • 2507 • 2551 • 2552
• Open-collector Input signals
2.1 Panel Installation
1. The panel mount transmitter is designed for installation using a 1/4 DIN Punch. For
