Product Overview
Positioner Design and Configuration
The ABB V18345-2010420001 is a TZIDC electro-pneumatic positioner from the TZIDC series. Therefore, this positioner is intelligent and configurable with an indicator and operator panel. The case is made of varnished aluminum with IP65 (NEMA 4X) protection. Consequently, the V18345-2010420001 suits mounting to linear actuators per DIN/IEC 534 or NAMUR standards. It also mounts to rotary actuators per VDI/VDE 3845 specifications. The mechanical position indicator provides clear visual feedback.
Output and Safe Position Configuration
The V18345-2010420001 features double acting output with fail-safe positioning. Therefore, in case of electrical power failure, the positioner moves the actuator to a safe position. The two-wire technology accepts a 4 to 20 mA nominal input range. Consequently, the positioner integrates seamlessly into existing control loops. The HART protocol 5.1 enables digital communication for configuration and diagnostics.
Construction and Environmental Protection
The aluminum housing features electrostatic dipping varnish with epoxy resin. Therefore, the case is stove-hardened for durability. The case is varnished black (RAL 9005) with a matte finish. Consequently, the V18345-2010420001 withstands harsh industrial environments. The IP65 and NEMA 4X ratings ensure protection against dust and water jets.
