The ABB TZIDC-200 is an intelligent electrical positioner.Model number V18348-10161310110 is its specific identifier.Product details are as follows:
Basic Information
Type:Electronically configurable positioner
Applications:Mounted on pneumatic linear or rotary actuators,suitable for hazardous areas requiring flameproof enclosures.
Communications:Supports HART communication protocol and comes standard with a local communication interface(LKS connector).
Technical Parameters
Input Signal:4-20mA two-wire technology,nominal range 4-20mA,split range configurable from 10%to 100%of nominal range,overcurrent protection 25mA/30V,maximum voltage drop 9.7V DC at 4mA,resistance 485 ohms at 20mA.
Digital Input:Control voltage 12-24V DC,maximum current 4mA.Output range:0-6 bar(0-90 psi),air flow rate is 5.0 kg/h(3.9 Nm³/h,2.3 scfm)at a supply pressure of 1.4 bar(20 psi),and air flow rate is 13 kg/h(10 Nm³/h,6.0 scfm)at a supply pressure of 6 bar(90 psi).With the spool valve option,the output range is 0-7 bar(0-100 psi),and air flow rate is 45 kg/h(20.0 scfm)at 7 bar(100 psi).
Air supply:Instrument air should be oil-,water-,and dust-free according to DIN/ISO 8573-1,with contamination and oil content class 3 and a dew point 10K below the operating temperature.Supply pressure is 1.4-6 bar(20-90 psi),or 1.4-7 bar(20-100 psi)with the spool valve option.
Operating temperature range:-40°C to+85°C.
Resolution:A/D conversion resolution greater than 4000 steps,sampling rate 20ms.
Features
Automatic control parameter adjustment:Control parameters are fully automatically determined and the positioner is adaptively adjusted to achieve optimal control.
Fail-safe and fail-lockout functions:In the”fail-safe”function,positioner Output 1 is depressurized in the event of a power failure,the pneumatic actuator’s return spring moves the valve to a safe position,and Output 2 of the double-acting actuator is pressurized.In the”fail-lockout”function,positioner Output 1 and Output 2(if available)are closed in the event of a power failure,and the pneumatic actuator locks the valve in its current position.In the event of a compressed air supply failure,the positioner depressurizes the actuator.
Easy operation and commissioning:A built-in operator panel with a 2-line LCD indicator and four operating buttons is provided for commissioning,configuration,and monitoring during on-site operation.Operation can also be performed via the provided communication interface using an appropriate configuration program.Comprehensive certifications:ATEX,FM,CSA,and IECEx certified,suitable for SIL2 safety circuits.
