Figure 3-10. Typical Signal Outputs
Signal Output Descriptions and Terminal Numbers
There are four sets of signal output connections on the X7 digital output
terminal block (see Figure 3-10). Pulse outputs IMP1 and IMP2 can be scaled
independently of one another. IMP1 is the primary scaled pulse output. IMP2
is the secondary scaled pulse output. IMP3 provides an ON signal for flow in
the forward direction, an OFF signal for flow in the reverse direction, and
random FLASH under no flow conditions.
The maximum frequency signal output is 500 HZ. Signal configurations of
1000 HZ are available through Anderson Instrument as a special order. The
open collector outputs are rated at 30 VDC maximum, 20 mA. Use a resistor
to limit current in the digital output circuit to 20 mA. A typical resistor is
1.5K ohm, 1/8 watt at 12 VDC.
Analog output terminal X8 has two connectors, 5 (-) and 6 (+). The active
analog output produces a 4 to 20 mA signal proportional to flowrate that will
drive a control loop with a maximum load of 500 ohms (see Figure 3-10).
