Isolated Pulse Output Module for the CDI flow meters. The pulse output built into CDI flow meters is an open-collector transistor output that functions as a switch to the meter’s ground. It does not provide electrical isolation between the meter and the receiving device. The CDI-IPO provides this isolation.

The pulse output built into CDI flowmeters is an open-collector transistor output that functions as a switch to the meter’s ground. It does not provide electrical isolation between the meter and the receiving device. The IPO provides this isolation.
The CDI 5200 IPO interface provides an optically-isolated output that simulates a relay contact. The output floats with respect to the meter’s ground, and eliminates the need for any direct electrical connection between the meter and the receiving device.
| Input Power: | 2mA @ 18-24vDC |
| Max Load Current: | 600mA |
| Blocking Voltage: | 60V |
| Output Resistance: | 0.8 Ohms |
| Isolation Voltage: | 1500 Volts |
Unscrew the cover of the meter and lift out the display circuit board. The blue jumper wire may be removed from the terminal block, if it is present. Install the 5200-IPO with its two pins in the PULSE and DISP + terminals, and tighten the screws. Connect the wires from the receiving device to the two terminals of the terminal block.
The two terminals are interchangeable. Do not connect a ground wire from the receiving device to the meter unless the meter is being powered by the receiving device.
Do not wire the IPO into a circuit in which the current could exceed 600 mA or the voltage could exceed 60 Volts. Do not connect the IPO between a voltage source and a common or neutral terminal without a suitable current-limiting resistor.
