INTRODUCTION
The UNICONT PDF-
01 and PDF-
01-6/A/C Ex devices are 2-wire on-site indicators that can be inserted into a 4 … 20 mA current loop without the need for
additional power supply. Since the displayed value is proportional to the input, the units are suitable for indication of temperature, pressure, level, etc. values,
the information carried by the loop current. The customer can program the engineering units and the indication range.
The HART capable UNICONT P
F-
01-4 and P
F-
01-8/B/D Ex 3-wire process indicators require additional power supply. Besides displaying the loop
current or the process values, these units convert input current to HART signals and so enable devices that have analogue outputs only to be integrated into
HART multidrop systems. The ratio between the input and output current can be programmed.
The intelligent electronics and HART communication enables versatile signal processing and remote programming. The software uses the Universal HART
commands No. 1-3, 6, 7, 11-18 and device specific commands No128-132, 135 and 139 of the HART Revision 5.
Robust enclosure makes applications under harsh conditions also possible. Explosion proof versions are available for hazardous environments.
