ABB V18345 Electro-Pneumatic Positioner Origin in Germany
Product Description
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
To linear actuators in accordance with the
standard Pos: 5.4 /Technische Daten / Datenblatt/Aktorik/Stellungsregler/Allgemein/Montage/Genormter Anbau an pneumatische Linearantriebe Lateral attachment is in accordance with DIN / IEC 534 (lateral
attachment to NAMUR). The required attachment kit is a complete
set of attachment material, but does not include the screwed pipe
connections and air pipes.
To rotary actuators in accordance with the
standard Pos: 5.6 /Technische Daten / Datenblatt/Aktorik/Stellungsregler/Allgemein/Montage/Genormter Anbau an pneumatische This attachment is designed for mounting according to the standard VDI/VDE 3845. The attachment kit consists of a console with mounting screws for mounting on a rotary actuator. The adapter for coupling the positioner feedback shaft to the actuator shaft has to be ordered separately. Screwed pipe connections and air pipes have to be provided on site.
Digital input
For the digital input, one of the following safety options can be
selected. You may use the operator’s panel or configuration program
to select an option.
- No function (default)
- Move to 0 % position
- Move to 100 % position
- Hold previous position
- disable local configuration
- Disable local configuration and operation
- Disable any access (no local or remote access via a PC)
The selected function is activated once the 24 V DC signal is no
longer applied (< 11 V DC).
Operating parameters
The following operating parameters can be set manually if required:
Signal
Signal min. 4 mA, max. signal 20 mA (0 ... 100 %)
freely selectable for split-range operation
min. range 20 % (3.2 mA)
recommended range > 50 % (8.0 mA)
Action (positioning signal)
Increasing: Signal 4 ... 20 mA = position 0 ... 100 %
Increasing: Signal 20 ... 4 mA = position 0 ... 100 %
Characteristic curve (travel = f {signal})
Linear, equal percentage 1:25 or 1:50 or 25:1 or 50:1 or freely
configurable with 20 reference points.
Travel limit
The positioning travel, i.e. the stroke or angle of rotation, can be
reduced as required within the full range of 0 ... 100 %, provided that
a minimum value of 20 % is observed.
Shut-off function
This parameter can be set separately for each end position. When
the respective configured limit value is exceeded, the shut-off
function causes immediate travel of the actuator until reaching the set
end position.
When the shut-off value is set to “0”, the position is further controlled,
even in the respective end position.
Travel time prolongation
This function can be used to increase the max. travel time for full
travel. This time parameter can be set separately for each direction.
