INPUT WIRING & SPECIFICATIONS

CAUTION

Risk of electric shock.

Dangerous and lethal voltages may be present on the input termi-

nals. Please take appropriate precautions to ensure safety.

CAUTION

Risk of danger.

The sensor input can potentially float to dangerous and unexpected volt-

ages depending on what external circuit it is connected to. Appropriate considerations

must be given to the potential of the sensor input with respect to earth common.

0/4–20mA DC is the most commonly used analog signal in industry, and is universally accepted.
As a current loop, it is unaffected by voltage drops in cables, and can be transmitted over long
distances without signal degradation.
