With the TZIDC designed for remote position sensors, the
positioner is supplied without a position sensor.
The housing (TZIDC Control Unit) contains the electronics and
pneumatics along with the following options, where applicable:
• Analog position feedback
• Digital position feedback
Any position sensor (4 to 30 kΩ, with line break detection
4 to 18 kΩ) can be connected.

4 Shielded connection cable
Connect the positioner (TZIDC Control Unit) and remote position
sensor while observing the following instructions:
• A shielded 3-wire cable with a maximum length of 10 m (33 ft)
must be used for the connection.
• Route the cable into the terminal compartment through the
EMC cable glands. Ensure that the shielding is secured
correctly in the EMC cable glands.
• Connect the cables in accordance with the electrical
connections and tighten the screws of the terminals so that
they are hand-tight.
• The electrical connection of the TZIDC Control Unit and the
optional modules are described in TZIDC / TZIDC Control
Unit terminal assignment on page 33.
• If the TZIDC Control Unit is fastened such that it is it non-
conductive, the housing must be grounded (TZIDC Control
Unit and remote position sensor housing with the same
electric potential); otherwise control deviations could occur
with regard to analog position feedback.
• Use wire end ferrules when connecting.
• The pneumatic outputs must be connected to the actuator
using cables of at least Ø 6 mm (0.23 in).
• If the device is being operated on a cylinder, for reasons
associated with linearity you should run automatic
adjustment for rotary actuators.
