ANALOG INPUTS AND OUTPUTS
Analog Inputs must be loop powered from the connected source. Input Channel 1 is typically used for
pH Input connection.
Analog Outputs are provided with 12 vdc loop power.

Digital Connector Pin Out
DIGITAL INPUTS AND OUTPUTS
These are TTL inputs and outputs. This means simple contact closure all that is needed on the inputs, and the
outputs provide 5 vdc with minimal current. They may be used to trip solid state relays with trigger voltages
of 3-5 vdc., or with other systems with similar inputs.
