ABB V18345-1021120001 TZIDC Electro-Pneumatic Positioner

The ABB V18345-1021120001 is a TZIDC electro-pneumatic positioner. This device is intelligent and configurable with an indicator and operator panel. 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 an aluminum case with IP65 (NEMA 4X) protection.

Technical Specifications of the V18345-1021120001

The ABB V18345-1021120001 uses a 4-20 mA input with LKS adapter. It includes an FSK module for HART communication. The housing is made of aluminum with electrostatic dipping varnish. The case is varnished black, RAL 9005, matt finish. The cap is Pantone 420.

Environmental Certifications and Protection

This unit has FM/CSA explosion protection approval. The ambient temperature range is -40°C to +85°C for operation. The same range applies for storage and transport. With SJ2-S1N proximity switches, the range is -25°C to +85°C. Operational relative humidity is 95% annual average with condensation allowed. Transport and storage humidity is 75% annual average, non-condensing.

Output and Safe Position

The output is double acting with fail freeze. In an electrical failure, the actuator freezes in position. The electrical connection uses 1/2-14 NPT thread. The air connection uses 1/4-18 NPT thread. The ABB V18345-1021120001 comes without analog position feedback. It also comes without mechanical feedback.

Electrical Connections Details

Screw terminals accept max 1.0 mm² for options. For analog signal, max wire size is 2.5 mm². Do not expose the terminals to strain. Cable entry uses two threads of 1/2-14 NPT or M20 x 1.5. One thread comes with a cable gland. The other thread comes with a pipe plug. Pneumatic connections use G 1/4 or 1/4-18 NPT threads.

Case Construction

The ABB V18345-1021120001 uses an aluminum case with IP65 / NEMA 4X protection. The surface uses electrostatic dipping varnish. The varnish is stove-hardened for durability. No mechanical indicator is present on this model.

Installation Guidelines for the V18345-1021120001

Mount the ABB V18345-1021120001 on linear or rotary actuators. Ensure FM/CSA requirements are met for hazardous locations. Use proper strain relief for all electrical connections. Do not allow terminal strain during wiring. Select the appropriate cable entry thread for your region. Use clean, dry instrument air for supply.
