Basic model
1)
1 LKS plug
2 Positioning signal 4 ... 20 mA / bus connector 9 ... 32 V DC
1)
3 Digital input
1)
4 Digital output
5 Supply air: 1.4 ... 6 bar (20 ... 90 psi)
6 Exhaust
7 I/P module with 3/3-way valve
8 Position sensor (optional up to 270° rotation angle)
IMPORTANT (NOTE)
With optional upgrades either the "Installation kit for digital feedback with proximity switches" (13) or the "Installation
kit for digital feedback with microswitches 24 V" (14) can be used.
In both cases, the "mechanical position indicator" (8) must be installed.

Functionality
The TZIDC, TZIDC-110, TZIDC-120 is an electronically configurable positioner with
communication capabilities designed for mounting on pneumatic linear or rotary actuators.
Fully automatic determination of the control parameters and adaptation to the final control
element yield considerable time savings and an optimal control behavior.
