With the TZIDC designed for remote position sensors, the
positioner is supplied without a position sensor.
The 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 k , with line break detection
4 to 18 k ) can be connected.

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 Positioner /
TZIDC Control Unit Electrical Connection on page 22.
• 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.
