ABB V18345-1010251001 TZIDC-120 Intelligent Positioner

The ABB V18345-1010251001 is a TZIDC-120 intelligent positioner. This device features an indicator and operator panel for local configuration. 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 protection.

Technical Specifications of the V18345-1010251001

The ABB V18345-1010251001 uses two-wire 4-20 mA input technology. The input 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.

Output and Safe Position

The output is single acting with fail freeze. In an electrical failure, the actuator freezes in position. The air pipe connection uses 1/4-18 NPT thread. The cable connection uses M20 x 1.5 thread. The ABB V18345-1010251001 includes a plug-in analog position feedback module. The feedback signal range is 4 to 20 mA.

Pneumatic Specifications

The supply pressure ranges from 1.4 to 6 bar (20 to 90 psi). Do not exceed the maximum operating pressure of your actuator. The air consumption is very low at less than 0.03 kg/h. This consumption stays independent of supply pressure.

Signal and Action Configuration

The ABB V18345-1010251001 supports direct or reverse signal action. Direct action means 4-20 mA signal equals 0-100% position. Reverse action means 20-4 mA signal equals 0-100% position. The characteristic curve options include linear and equal percentage. You can also configure freely with 20 reference points.

Accuracy and Performance

The characteristic deviation is ≤ 0.5%. The tolerance band adjusts from 0.3 to 10%. The dead band adjusts from 0.1 to 10%. The A/D conversion resolution exceeds 4000 steps. The sample rate is 20 milliseconds.

Environmental Influences

The influence of ambient temperature is ≤ 0.5% per 10°C change. The influence of vibration is ≤ ±1% up to 10g and 80 Hz. The ABB V18345-1010251001 meets DIN/IEC 68-3-3 Class III seismic requirements. Mounting orientation has no effect on performance.

Installation Guidelines for the V18345-1010251001

Mount the ABB V18345-1010251001 on linear or rotary actuators. Use clean, dry instrument air for supply. Do not exceed the actuator's maximum operating pressure. Set the characteristic curve using the operator panel. Configure direct or reverse action based on your application. Adjust dead band and tolerance band for optimal control.
