• A99
• NTC 2k2 ohm
• Ni1000 JC
• Ni1000 JC Extended
• Ni1000 Landis and Gyr
• Ni1000 DIN
• Pt1000
• Ratiometric
The measurement unit is also configurable to enable the controller to
propagate via network the measured value according to the appropriate
scale unit. Available configurable units are:
• Temperature
• Percentage
• Air Pressure
• Liquid Pressure
• Flow
• Concentration
• Ampere
• Voltage
A configurable filter constant in seconds is performed by the FX15 on
its Analog Inputs for the reduction of signal instability. An additional
Anti-Spike filter can be configured to limit the rate of change of the
input values to the value indicated by this attribute.
The FX15 provides a jumper configurable (Terminal 13) +5V AVPS
(Analog Voltage Power Supply) or a +16V External VDC, supply for
active analog input sensors (See
Jumper Details at page 12)
The EXT VDC can supply up to 80 mA for a maximum of four 0/4-20
mA active sensors. The AVPS can supply up to 10 mA for ratiometric
sensors.
Connecting Active 0-10 V Sensors
The FX15 can accept all the active temperature, pressure, flow and
humidity sensors providing 0-10 VDC signals.
Figure 32 shows the connection between an FX15 and an HT-9001
probe.
