RANGE OF VALUES ALLOWED FOR SET PULSES/VOL
• Minimum: 0.0
• Maximum: 99,999
HARDWARE SIGNALS
POUT-1 and POUT-2
• POUT-1 and POUT-2 are open collector outputs with an internal pull-up resistor (2.2K) tied to Input V. The
output voltage can be set to either 5, 12, or 24 volts depending on the location of the pulse voltage selector
jumper wire (see Figure 40).
• Typical duty cycle: variable length square wave
• Minimum period: 1.072 ms
• Maximum frequency: 933 Hz
• Minimum lag time: 460 ms (if within flow rates)
