ABB V18345-2011221001 Digital positioner TZIDC communication via HART

V18345-2011221001: intrinsically safe explosion-proof type.

Basic functions and features: It adopts microprocessor control, takes TEIP11 as the core component, combines microprocessing technology, and has built-in communication function. It has high positioning accuracy and large travel range, with a linear travel of 20-150mm and a rotary travel of 125 degrees. The gas capacity is ≥13.5kg/hour and the gas consumption is ≤0.03kg/hour. The debugging process can be simplified through the automatic zero/span adjustment function. It uses sensor technology for temperature and position compensation, with a vibration resistance of up to 10g, 10-150Hz, and an operating temperature range of -40℃ to +85℃.

Structural design: The housing is made of aluminum alloy, painted, with a protection level of IP65 (NEMA 4X), which is sturdy and durable and can adapt to a variety of harsh environments. It can be installed on linear actuators that meet DIN/IEC 534/NAMUR standards, as well as angular actuators that meet VDI/VDE 3845 standards, and can also be installed as a whole.

Safety features: It is an intrinsically safe explosion-proof product and can be used in hazardous areas where flammable and explosive gases or dust exist. It can effectively prevent safety accidents such as explosions caused by sparks or thermal effects generated by electrical equipment, and ensure safe and reliable operation in hazardous environments.

Communication and operation: It is equipped with HART communication protocol as standard, and can interact with the control system through the HART communication interface to achieve remote monitoring and parameter adjustment. It also has a local operation panel with a two-line LCD display and four operation buttons to facilitate on-site parameter configuration, debugging and operation monitoring.

Input and output configuration: The input is a 4-20mA signal, which uses a two-wire connection and has a plug for the LKS adapter. It has an analog position feedback function, and the feedback signal range is 4-20mA, which is realized through a plug-in module. In terms of fault safety, it is a single-acting, fault-locking (three-break protection) design, that is, when there is a power failure, gas failure, or signal failure, the valve can be kept in the current position to ensure system safety. In terms of connection, the cable thread is 1/2-14NPT and the air pipe thread is 1/4-18NPT.

In summary, the ABB TZIDC V18345 - 2011221001 positioner is widely used in industrial fields such as petroleum, electricity, metallurgy, papermaking, and water treatment due to its high-precision positioning, good environmental adaptability, rich communication functions, and reliable safety performance. It can accurately control pneumatic control valves and ensure the stable operation of industrial processes.
