Technical data

10.2 Output

10.2.1 Output signal

Relay, transmitter power supply (standard)

Current, voltage, pulse, intrinsically safe transmitter power supply (option)

10.2.2 Signal on alarm

No measured value visible on the LC display, no background illumination, no sensor power

supply, no output signals, relays behave in safety-oriented manner.

10.2.3 Current/voltage output

Span:

• 0/4 to 20 mA (active), 0 to 10 V (active)

Load:

• ≤ 600 Ω (current output)

• Max. loop current 22 mA (voltage output)

Signal characterization:
