ABB V18345-1027420001 TZIDC Electro-Pneumatic Positioner

The ABB V18345-1027420001 is a TZIDC electro-pneumatic positioner. This device provides precise valve control 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 varnished aluminum case with IP65 (NEMA 4X) protection.

Technical Specifications of the V18345-1027420001

The ABB V18345-1027420001 uses a 4-20 mA input with two-wire technology. It includes a connector plug for LKS adapter. The housing is made of varnished aluminum. The protection rating is IP65 (NEMA 4X) for harsh environments. The design uses standard varnish and coding.

Explosion Protection Certification

This unit has GOST Russia explosion protection approval. The certification is Ex II 2 G EEx ib II C T6. This makes the ABB V18345-1027420001 suitable for hazardous locations. Always follow local regulations for installation in explosive atmospheres.

Output and Safe Position

The output is double acting with fail safe. In an electrical power failure, the actuator moves to a safe position. The cable connection uses 1/2-14 NPT thread. The air pipe connection uses 1/4-18 NPT thread. The ABB V18345-1027420001 comes without analog position feedback. It also comes without mechanical feedback.

Input Signal Details

The nominal input range is 4 to 20 mA. Split range configuration works between 20% and 100% of nominal range. 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.

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 V18345-1027420001 includes a digital input for control. The control voltage is 24V DC with a 12-30V DC range.

Pneumatic Output 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. A booster is available on request for higher flow. The output function works for single or double acting actuators.

Travel and Limit Configuration

The shut-off values are configurable. End position 0% ranges from 0 to 45%. End position 100% ranges from 55 to 100%. For rotary actuators, the used angle range is 25 to 120 degrees. An optional 270 degree range is available. For linear actuators, the used range is 25 to 60 degrees.

The ABB V18345-1027420001 allows travel limit configuration. Min and max limits are freely configurable within 0 to 100% of total travel. The minimum range must exceed 20%. Travel time prolongation ranges from 0 to 200 seconds. This can be set separately for each direction. The positioning time limit ranges from 0 to 200 seconds.

Physical Dimensions

The dimensions are 16.85 cm in depth. The width is 9.29 cm. The height is 8.95 cm. The ABB V18345-1027420001 weighs 1.70 kg.

Installation Guidelines for the V18345-1027420001

Mount the ABB V18345-1027420001 on linear or rotary actuators. Ensure GOST explosion protection requirements are met for hazardous locations. Use clean, dry instrument air for supply. Configure the fail safe direction based on your application. Set travel limits and time parameters as needed. Verify the positioning time limit matches your process requirements.
