Data Sheet 902931 Page 2/10
Technical data
Input
Number of transmitters Up to 16 transmitters can be received per receiver.
Radio frequency 868.4 MHz (Europe);
915 MHz (America, Australia, Canada, and New Zealand);
Ten frequencies can be configured in the 915 MHz frequency band.
Open air range Up to 300 m when using the antenna wall holder with a 3 m antenna cable
When installing the antenna directly to the receiver, a reduced range of approx. 40 % must be
taken into account.
Measuring range limits Depending on the set sensor
Configuration Using the keys on the device or the setup program
Unit The units for temperature, pressure, potentiometer, and voltage
are configurable on the device or with the setup program.
Analog outputs
Quantity 4 analog outputs for basic type 902931/10, 2 analog outputs for basic type 902931/30
Output signal:
- Current
- Voltage Configurable with the keys on the device or the setup program
Load-independent direct current 0 to20 mA or 4 to 20 mA
Direct voltage 0 to 10 V
Transmission behavior Linear, freely scalable
Burden (at current output) ≤ 500 ohm
Load (at voltage output) ≥ 10 k ohm
Setting time for temperature changes The setting time depends on the transmission interval that is set in the transmitter.
Setting time after switch-on or reset
≤
5 s
Calibration conditions AC 230 V/22 °C (±3 K) or DC 24 V/22 °C (±3 K)
Accuracy
≤
±0.1 %
1
(accuracy includes calibration, linearization, burden influence, load error,
and voltage supply error)
Residual ripple
≤
±0.2 %
1
Electrical isolation The analog outputs are electrically isolated from each other and the interfaces.
Isolation voltage 50 V
Measuring circuit monitoring of the analog outputs
Underrange
- Current output 4 to 20 mA
- Current output 0 to 20 mA
- Voltage output 0 to 10 V
Dropping to 3.8 mA, then jump to the configured signaling
Dropping to -0.1 mA, then jump to the configured signaling
Dropping to -0.1 V, then jump to the configured signaling
Overrange
- Current output 4 to 20 mA
- Current output 0 to 20 mA
- Voltage output 0 to 10 V
Increasing to 20.5 mA, then jump to the configured signaling
Increasing to 20.5 mA, then jump to the configured signaling
Increasing to 10.25 V, then jump to the configured signaling
Probe short-circuit or
Probe/cable break and alarms:
- Current output 4 to 20 mA
- Current output 0 to 20 mA
- Voltage output 0 to 10 V
Positive signaling: > 21 mA
Negative signaling: < 3.6 mA
Positive signaling: > 21 mA
Negative signaling: < -0.1 mA
Positive signaling: > 10.5 V
Negative signaling: < -0.1 V
Output behavior The output behavior (positive or negative signaling) can be configured.
