The TZIDC-220 is a digital positioner for pneumatic linear or rotary actuators with PROFIBUS PA® communication, designed for use in hazardous environments. It features a compact aluminum housing with IP65/NEMA 4X rating, weighing 3.0 kg, and supports mounting per DIN/IEC 534 for linear actuators or VDI/VDE 3845 for rotary actuators. The device operates in ambient temperatures from −40 to 85 °C and accepts supply air pressures from 1.4 to 6 bar (20 to 90 psi), with a marine version rated to 1.6 to 5.5 bar (23 to 80 psi). It meets ATEX, IECEx, cFMus, EACEx, and DNV explosion protection approvals, with flameproof and intrinsic safety variants. The positioner includes a two-line LCD display and four buttons for local operation, and supports automatic commissioning. Pneumatic outputs are configurable for single-acting or double-acting actuators with fail-safe or fail-freeze functions.
The TZIDC-220 features a small and compact design, a modular construction, and an excellent cost-performance ratio. Fully automatic determination of the control parameters and adaptation to the final control element yield considerable time savings and an optimal control behavior.
