ABB DIGITAL POSITIONERS Performance for harshest environments

The TZIDC and EDP300 series digital positioners provide flexible

and cost-effective valve management and control. Their durability

and unmatched shock and vibration immunity up to 10 g and 80 Hz

means that they are suitable for use even under harsh conditions.

The challenge – handling over 100.000 strokes a year

Most control valves in many processes will rarely

have to move, commonly enabling operators to opt

for positioners with lifetimes of less than 100.000

strokes. However, there are some applications

where valves will need to handle frequent changes

in process conditions. In such applications, where

100.000 strokes may occur in a single year alone,

there is a need for a positioner that can handle

these changes with minimal need for maintenance.

The solution – unrivalled performance performing

1.000.000 strokes

The answer is ABB’s TZIDC positioner. In a four

month trial, an ABB TZIDC positioner underwent

a customer durability test which saw it perform

1.000.000 strokes without any deterioration in

performance or fault or interruption.

Offering remote communication via 4 to 20 mA

HART, PROFIBUS PA or Foundation Fieldbus,

the TZIDC sets the standard for safe and eco

nomic control of industrial processes. Its built-in

intelligence enables it to adapt itself to any

control valve at the push of a button, while a

host of service, diagnostic and safety functions,

including fail-freeze and fail-safe action, help to

provide a high level of operational performance.

The TZIDC and EDP300 is suitable for use with

linear, part-turn, and single or double-acting actu

ators and is protected to IP65/NEMA 4X, making

it ideal for harsh environments. You can rely on

the TZIDC and EDP300 to provide the highest

levels of availability, enabling you to maximize

the profitability of your process through improved

plant uptime.
