Electro-Pneumatic Positioner TZIDC: Key Features and Specifications

The modular design allows for future enhancements through retrofitting optional equipment. These include plug-in modules for analog or digital position feedback and a shutdown module. Additionally, mechanical position indicators, proximity switches, or 24 V microswitches can be installed for independent position signaling.

Technical Specifications and Environmental Capabilities

The TZIDC boasts impressive technical specifications:

• Input: 4-20 mA two-wire technology, with a nominal range and configurable split ranges (20-100%). Digital input for control voltages (0-5V DC for logic "0", 11-30V DC for logic "1").

• Output: Compressed air output ranging from 0-6 bar (0-90 psi), with air capacities up to (10Nm3/h or 6.0sfcm) at 6 bar supply pressure. Digital output for control circuits.

• Travel: Rotation angles of 25-120° (optional 270° for rotary actuators) and travel limits of 25-60 mm for linear actuators.

• Air Supply: Requires instrument air free of oil, water, and dust (acc. to DIN/ISO 8573-1), with a supply pressure of 1.4-6 bar (20-90 psi). Air consumption is minimal, less than 0.03kg/h (0.015scfm).

• Performance: Characteristic deviation ≤0.5%, adjustable tolerance band (0.3-10%), and dead band (0.1-10%). Resolution is greater than 4000 steps with a sample rate of 20 ms.

• Environmental: Operates reliably in ambient temperatures from -40 to 85°C (-40 to 185°F) and relative humidity of 95% (annual average, condensation permissible). The housing is made of aluminum with IP 65 / NEMA 4X protection, featuring an electrostatic dipping varnish. It meets seismic requirements of DIN/IEC 68-3-3 Class III and is unaffected by mounting orientation.

The TZIDC positioner is a robust, flexible, and high-performance solution for precise pneumatic actuator control in diverse industrial environments, backed by comprehensive safety certifications and advanced communication capabilities.
