Brief description

The TZIDC-200 is an electronically configurable positioner with communication capabilities designed for mounting to pneumatic linear or part-turn actuators. It 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.

Pneumatics

ABB TZIDC-200 Digital Positioner V18348 Positioner

An I/P module with subsequent pneumatic amplifier is used to control the pneumatic actuator. The well-proven I/P module

proportionally converts the permanent electrical setpoint signal from the CPU into a pneumatic signal used to adjust a 3/3-way valve.

The air flow for pressurizing or depressurizing the actuator is continuously adjusted. As a result, excellent control is achieved. When reaching the setpoint, the 3/3-way valve is closed in center position to minimize the air consumption.

Four different pneumatics versions are available: for singleacting or double-acting actuators, each with “fail-safe” or “failfreeze”function.

“Fail-safe” function

If the electrical supply power fails, the positioner output 1 is depressurized, and the pneumatic actuator’s return spring moves the valve to the defined safe position. In case of a double-acting actuator the second output 2 is additionally pressurized.
