SITRANS FX300
ELECTRICAL CONNECTIONS 4
The pulse output is a passive "open collector" output which is electrically separated from the current interface and the measuring sensor. It can be configured as a high current output or NAMUR output using a jumper on the amplifier board.
Jumper in NAMUR setting
Ri = 900 Ω
Umax = 36 VDC
The maximum frequency of the pulse output is fmax = 0.5 Hz
Jumper in high current setting
Open: | Maximum voltage Umax = 36 VDC | Closed current IR < 1 mA |
Closed: | Maximum current Imax = 100 mA | Voltage U < 2 VDC |
The maximum frequency of the pulse output is fmax = 0.5 Hz
