Pneumatic connection
30 TZIDC, TZIDC-110, TZIDC-120 42/18-84-EN
All pneumatic piping connections are located on the right side of the positioner. To connect the
pneumatic pipes, G1/4 or 1/4-18 NPT tap holes are provided. The positioner is labeled
according to the tap holes available. The corresponding pipe connections must be included.
The level of supply pressure must be adjusted to the output pressure in the actuator required to
provide increased actuating force. The operating range for the positioner is between 1.4 ... 6 bar
(20 ... 90 psi).
Arrange the connections according to their marks:
Designation Pipe connection
- Air supply, pressure 1.4 ... 6 bar (20 ... 90 psi)
OUT1 Output pressure for actuator
OUT2 Output pressure for actuator (2nd connection with double-acting actuator)
