Isolating-Signal-Converter TV 501-Ex
with intrinsically safe outputs
Features
M Universal inputs 0/4 ... 20 mA and 0/2 ... 10 V
M Intrinsically safe outputs Ex II (1) G [Ex ia Ga] IIC
Ex II (1) D [Ex ia Da] IIIC
for 0/4 ... 20 mA simultaneous 0/2 ... 10 V
M Supply voltage 10 ... 30 V AC/DC or
85 ... 253 V AC/110 ... 125 V DC
M Full 3-port isolation
M Power on LED
M 22.5mm case for TS35 DIN rail mounting
General information
Isolating signal converter TV501 can be used to isolate and convert 0/4 ... 20 mA and 0/2 ... 10 V signals to the
hazardous area. The universal design of the in- and outputs and the wide range of supply voltage limits the devices into 2 models.
Short information
Current output Ex-i
Max. burden ≤ 1 kΩ. Useful to drive I/P Transmitters, proportional valves and loop
powered panelmeter installed in hazardous areas.
The connected devices need to be certified depending on operation-places.
Multi-range
Inputs and outputs are configurable between 0/4 ... 20 mA and 0/2 ... 10 V by
DIP-switches at the front panel.
