Power Supply Operative Limits; Ped Information Integration - ABB 2600T Pressure Transmitter Series User Manual

364xS User's Manual

Power supply operative limits

The transmitter operates on a minimum voltage of 10.5 Vdc to a maximum of 42 Vdc and is protected
against polarity inversion.
Note The transmitter operates from 10.5 to 42 Vdc with no load (additional load allows operation over
42 Vdc). For EEx ia and intrinsically safe (FM, CSA and SAA) approval power supply must not exceed
30 Vdc. In some countries the maximum power supply voltage is limited to a lower value.
Minimum operating voltage is 15.3 Vdc if on terminals for external meter neither link nor remote indicator is
present.
The total loop resistance is indicated in the expression below.
R (kohm) = (Supply voltage - Minimum operating voltage) / 22.5
The total loop resistance is the sum of the resistance of all elements of the loop, including wiring,
conditioning resistor, safety barriers and additional indicators (excluding the equivalent resistance of the
transmitter). Where a configuration device (HART), such as the Hand Held Communicator or a Modem is
likely to be used, a resistance of 250 ohm minimum should be present between the power supply and the
point of insertion of these devices, to allow communication.
Several types of safety barriers, either passive or active, can be satisfactorily used in conjunction with the
364 pressure transmitter models. Nevertheless, in case of use of active barriers, check with the supplier if
the model is suitable for use with smart transmitters allowing the connection of the configuration devices in
the "safe" or non-hazardous area.

PED information integration

The transmitter may be used in compliance with the Pressure Equipment Directive 97/23/EC in compliance
with article 3 comma 3. It is recommended to select the correct fail safe mode for the 4-20 mA signal (as per
Namur NE43 recommendation). See also the relevant instructions about the failsafe direction in this manual
For Safety reason the use of the transmitter is limited as following described.
