The TZIDC is an electronically configurable positioner with
communication capabilities designed for mounting to pneumatic
linear or rotary actuators. It features a small and compact design, a
modular construction, and an excellent cost-performance ratio.
Fully automatic determination of the control parameters and
adaptation to the final control element yield considerable time savings
and an optimal control behavior.

An I/P module with subsequent pneumatic amplifier is used to control
the pneumatic actuator. The well-proven I/P module proportionally
converts the permanent electrical positioning signal from the CPU
into a pneumatic signal used to adjust a 3/3-way valve.
The air flow for pressurizing or depressurizing the actuator is
continuously adjusted. As a result, excellent control is achieved.
When reaching the set point, the 3/3-way valve is closed in center
position to minimize the air consumption.
Four different pneumatics versions are available: for single-acting or
double-acting actuators, each with “fail-safe” or “fail-freeze” function.

If the electrical power supply fails, the positioner output 1 is
depressurized, and the pneumatic actuator’s return spring moves the
valve to the defined safe position. In case of a double-acting actuator
the second output 2 is additionally pressurized.

If the electrical power supply should fail, the positioner output 1 (and
2, if applicable) is closed and the pneumatic actuator stops
(“freezes”) the valve in the current position. If compressed air supply
should fail, the positioner depressurizes the actuator.

The positioner has a built-in operating panel providing a 2-line LCD
and 4 pushbuttons for optimal local configuration, commissioning and
operational monitoring.
Alternatively, the appropriate configuration program and the available
communication option can be used.

The standard TZIDC model has a local communication interface (LKS
connector). Additionally, a “HART communication” option for
communication via the 20 mA signal is available. Both
communications are based on the HART Protocol.

In addition to its input for the analog position set point the TZIDC
positioner is equipped with a digital input which can be used to
activate various protective functions in the device via the process
control system. A digital output allows you to output collective alarms
or fault messages.

TheTZIDC basic model can be enhanced at any time by retrofitting
optional equipment. Option modules for analog or digital position
feedback or a shutdown-module can be installed. Additionally, a
mechanical position indicator, proximity switches or 24 V
microswitches are available for indicating the position independently
of the mother board function.
