20 mA sensor
A 4 to 20 mA (0 to 20 mA) sensor can be connected on the voltage input
using an external 500 Ω resistor (twice 1 kΩ in parallel).
Figure 42:20 mA sensor
① Analog sensor
The following values apply:
• 4 mA = 2.0 V
• 10 mA = 5.0 V
• 20 mA = 10.0 V
(according to U = R
.
I=500Ω
.
10 mA = 5.0 V)
Modules with ..TAP13.. in their designation are provided with an additional
analog output.
Connecting analog inputs of the EASY4..-DC-ME expansion units
These DC expansion units allow you to process analog values of voltage,
current and temperature. The EASY4..-DC-ME DC expansion units convert
analog input and output values with a 10-bit resolution (0 - 1023).
When a Pt100 sensor is connected, the DC expansion units operate in the
range between -50 °C and 200 °C.
