ABB TZIDC Digital Positioner

ABB TZIDC Digital Positioner

■ The TZIDC is an electronically configurable positioner with communication capabilities designed for mounting to pneumatic linear or rotary 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.

ABB TZIDC Digital Positioner

■ “Fail-freeze” function

If the electrical power supply should fail, the positioner output 1 (and 

2, if applicable) is closed and the pneumatic actuator stops (“freezes”) 

the valve in the current position. If compressed air supply should fail, 

the positioner depressurizes the actuator.

■ “Fail-safe” function

If the electrical power supply 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.


■ Input

Setpoint signal (two-wire technology)

Nominal range        4 ... 20 mA

Split range configuration between 20 ... 100 % of the nominal range

Max.                                  50 mA

Min.                                   3.6 mA

Starting at                        3.8 mA

Load voltage at              20 mA 9.7 V

Impedance at                20 mA 485 Ω

Digital input

Control voltage             0 ... 5 V DC

logical switching state "0" 11 ... 30 V DC

logical switching state "1"

Current max.                4 mA


■ Output

 

Compressed air output Range      0 ... 6 bar (0 ... 90 psi)

Air capacity                                      5.0 kg/h = 3.9 Nm3/h = 2.3 sfcm at 1.4 bar (20 psi) supply pressure

                                                           13 kg/h = 10 Nm3/h = 6.0 sfcm at 6 bar (90 psi) supply pressure

Output function

                                                           For single or double-acting actuators, air is vented from actuator or

                                                           actuator is blocked in case of (electrical) power failure

Shut-off values

                                                          End position 0 % = 0 ... 45 %

                                                          End position 100 % = 55 ... 100 %

Digital output (control circuit to DIN 19234 / NAMUR)

Supply voltage                                       5 ... 11 V DC

Current >0.35 mA ... < 1.2 mA     Switching state logical "0"

Current > 2.1 mA                                 Switching state logical "1"

Effective direction (configurable)     normally logical "0" or logical "1"
