ABBV18345 Electro-Pneumatic Positioner

The ABBb TZIDC intelligent positioner, with the model number V18345 (standard model TZIDC - 100), is a sophisticated electro-pneumatic positioner. It combines high precision, adaptable control functions, and easy commissioning. It can be used for both single and double-acting actuators and offers fail-safe modes such as open/close or hold the last position. The standard model has HART communication and is compatible with PROFIBUS. There are also variant models like TZIDC - 110 (V18346 with PROFIBUS) and TZIDC - 120 (V18347 with fieldbus) for different communication requirements. It is suitable for both general and hazardous areas, with certifications like FM/ and ATEX. It features a built-in operating panel with a 2-line LCD display and four operating buttons for easy commissioning, configuration, and real-time monitoring



Advantages

Time Savings: The fully automatic determination of control parameters and their adaptation to the actuator save a significant amount of time during installation and maintenance.

Safety: Suitable for hazardous areas with FM/ and ATEX approvals. Offers fail-safe functions to ensure process safety even in demanding situations.

Versatility: Compatible with various pneumatic actuators (all sizes and types) and both linear and rotary control valves. Multiple communication options allow for easy integration into different control systems.

Cost-Effective: With its modular construction and high performance, it provides an excellent cost-performance ratio.
