Connect the analog outputs (optional)
Electrocution hazard. Always remove power to the instrument before making electrical connections.
If the instrument has the optional analog output card, the instrument has four 4–20 mA analog
outputs. Such outputs are commonly used for analog signaling or to control other external devices.
Connect each analog output to an external device as necessary. Refer to
connect the analog outputs. Use the mobile application to configure each of the analog outputs to
agree with a measured parameter (e.g., pH or temperature).
Make connections with twisted-pair shielded wire and connect the shield to the shield terminal.
• Do not connect the shield at both ends of the cable.
• Use of non-shielded cable may result in radio frequency emission or susceptibility levels higher
than allowed.
• Maximum loop resistance is 500 Ω.
Notes:
• The analog output terminals accept 15 to 26 AWG wire.
• The analog outputs are isolated from the other electronics, but are not isolated from each other.
• The analog outputs are self-powered. Do not connect to a load with voltage that is independently
applied.
• The analog outputs cannot be used to supply power to a 2-wire (loop-powered) transmitter.
