Cameron Scanner 3100 EFM - Analog Inputs; Pulse Inputs

Analog Inputs
The analog inputs (Figure 3.7), which can be congured for a 0 to 5 V, 1 to 5 V, 0 to 20 mA or 4 to 20 mA signal, can
be used to receive readings from a pressure or temperature transmitter for use in any ow run. Alternatively, they can be
used to log measurements from any device with a 0 to 5 V, 1 to 5 V, 0 to 20 mA or 4 to 20 mA output. An on-board resis-
tor is automatically enabled when a current input is congured in the Scanner 3100 web interface. Therefore, no external
resistor is required for use with a current input.
The Scanner 3100 provides approximately 10 VDC at 20 mA for powering a 0 to 5 V or 1 to 5 V transmitter. It is not
suitable for powering a 4 to 20 mA transmitter. For reduced power consumption, disable analog inputs in the Scanner
3100 web interface when they are not in use.

Pulse Inputs
Pulse inputs (Figure 3.8) provide an input for high-amplitude pulse (frequency) signals, such as signals from a turbine
meter equipped with a preamplier (shown at left) or signals from a positive displacement meter (shown at right).
