ABB V18345-1010551001 TZIDC-120 Intelligent Positioner

The ABB V18345-1010551001 is a TZIDC-120 intelligent positioner. This device provides precise valve positioning for industrial automation. You can mount it on linear actuators per DIN/IEC 534 standards. It also fits rotary actuators according to VDI/VDE 3845. The unit comes in a durable aluminum case with IP65 protection.

Technical Specifications of the V18345-1010551001

The ABB V18345-1010551001 uses two-wire 4-20 mA input technology. The nominal input range is 4 to 20 mA. The maximum input is 25 mA at 30V. The minimum starting current is 3.8 mA. Without analog feedback, the minimum is 3.4 mA. With analog feedback, the minimum is 3.5 mA.

Input and Communication Details

The load voltage at 20 mA is 8.7V DC without explosion protection. The impedance at 20 mA is 435 ohms without explosion protection. The ABB V18345-1010551001 includes a digital input for control. The control voltage is 24V DC with a 12-30V DC range. The digital output follows DIN 19234 / NAMUR standards.

Output and Pneumatic Specifications

The output range spans 0 to 6 bar (0 to 90 psi). Air capacity reaches 5.0 kg/h at 1.4 bar supply pressure. At 6 bar supply pressure, air capacity is 13 kg/h. The ABB V18345-1010551001 is double acting with fail freeze. In an electrical power failure, the actuator freezes in position. The output works for single or double acting actuators.

Housing and Protection

The case is made of varnished aluminum. The protection rating is IP65 (NEMA 4X). This suits harsh industrial environments. The ABB V18345-1010551001 uses cable connection with M20 x 1.5 thread. The air pipe connection uses 1/4-18 NPT thread.

Position Feedback

This unit includes a plug-in analog position feedback module. The signal range is 4 to 20 mA. This provides continuous position monitoring to your control system.

Installation Guidelines for the V18345-1010551001

Mount the ABB V18345-1010551001 on linear or rotary actuators. For linear actuators, follow DIN/IEC 534 guidelines. For rotary actuators, follow VDI/VDE 3845 standards. Use clean, dry instrument air for supply. Ensure proper grounding for the electrical connections. Set the shut-off values between 0-45% for 0% end position. Set shut-off values between 55-100% for 100% end position.
