INSTALLATION MT100 Multipoint Flow Meter
Source/Sink Outputs
Wire the source/sink outputs via the J8 Phoenix connector terminals as required for your device (using sink and/or source output as
appropriate) as shown in Figure 27 and Figure 28 below. The connector accepts 28-16 AWG (0.14 mm
2
-1.5 mm

) wire. The source/sink
outputs provide a pulse (frequency) output. Observe the output power limits listed below.
● Sink Output: 40 VDC maximum, 150 mA maximum (external, user-supplied power source)
● Source Output: 22 ±2 VDC output, 25 mA maximum (supplied by the flow meter)
