17.2 Output
17.2.1 Output signal
Designation Option
1)
PNP switch 4 to 20 mA output (4-wire), IO-Link 7
PNP switch output (3-wire) 4
2 x PNP switch output (4-wire), IO-Link 8
1) Product Configurator, order code for "Output"
17.2.2 Range of adjustment
• Switch output
Switch point (SP): 0.5 to 100 % in increments of 0.1% (min. 1 mbar * (0.015 psi)) of the
upper range limit (URL) switchback point (RSP): 0 to 99.5% in increments of 0.1% (min.
1 mbar * (0.015 psi)) of the upper range limit (URL)
Minimum distance between SP and RSP: 0.5 % URL
• Analog output (if available)
Lower range value (LRV) and upper range value (URV) can be set anywhere within the
sensor range (LRL - URL). Turn down for analog output up to 5:1 of upper sensor limit
(URL).
• Factory setting (if no customer-specific setting is ordered):
Switch point SP1: 90 %; switchback point RP1: 10 %;
Switch point SP2: 95 %; switchback point RP2: 15 %;
Analog output: LRV 0 %; URV 100 %
* For measuring ranges with a negative gauge pressure up to 4 bar (60 psi), the increment
when setting the switch point is min. 10 mbar (0.15 psi)
17.2.3 Switching capacity
• Switch state ON
3)
: I
a
≤ 200 mA
4)
; switch state OFF: I
a
≤100 μA
• Switch cycles: >10,000,000
• Voltage drop PNP: ≤2 V
• Overload protection: Automatic load testing of switching current;
– Max. capacitive load: 1 μF at max. supply voltage (without resistive load)
– Max. cycle duration: 0.5 s; min. t
on
: 40 μs
– Periodic disconnection from protective circuit in the event of overcurrent (f = 2 Hz) and
"F804" displayed
17.2.4 Signal range 4 to 20 mA
3.8 mA to 20.5 mA
17.2.5 Load (for devices with analog output)
In order to guarantee sufficient terminal voltage, a maximum load resistance R
L
(including
line resistance) must not be exceeded depending on the supply voltage U
B
of the supply
unit.
The maximum load resistance depends on the terminal voltage and is calculated according
to the following formula:
3) 100 mA can be guaranteed over the entire temperature range for the switch outputs "2 x PNP" and "1 x PNP + 4 to 20 mA output". For lower
ambient temperatures, higher currents are possible but cannot be guaranteed. Typical value at 20 °C (68 °F) approx. 200 mA. 200 mA can be
guaranteed over the entire temperature range for the "1 x PNP" current output.
4) Larger currents are supported, thus deviating from the IO-Link standard.
