PROFIBUS PA pressure transmitter
PROFIBUS PA transmitters are designed to be connected to the DP / PA segment coupler /
linking device. The permissible terminal voltage is within the range of 10.2 ... 32 VDC.
Use of a shielded cable is recommended. The shielding is bonded by means of the metal cable
gland.
IMPORTANT (NOTE)
The transmitter must be grounded.
The switch-on behavior corresponds to Draft DIN IEC 65C/155/CDV of June 1996. If the
transmitter is operated on an Ex segment coupler / linking device in accordance with
DIN EN 61 158-2 of October 1994, time-dependent current limiting may cause the maximum
number of devices to be reduced.
The "OUT" variable is transmitted cyclically. This consists of the output value and 1 byte of
status information. The output value is transmitted with 4 bytes as an IEEE 754 floating-point
type.
