What it is
The ABB PSTEK is a remote keypad (HMI) accessory for ABB's PST series softstarters, listed as Type Accessories and shipped with a 10 ft cable. It is not a standalone controller — it is the pendant-style operator interface that talks to a PST softstarter mounted elsewhere in the panel or on the motor. Compatibility is family-wide within the PST line, so one keypad covers parameter viewing, start/stop control and fault readout across the softstarter model range it is wired to.
Where it lives in the panel
The 10 ft cable lets the keypad mount on the cabinet door or an operator station while the PST softstarter sits inside the enclosure — useful when the starter is behind a barrier or in a section the operator cannot reach directly. No additional supply is implied beyond the cable run back to the softstarter.
Sourcing the PSTEK
No production-status entry is on record for the PSTEK, so active or obsolete status is not asserted. It is sourced to order against an RFQ as an ABB PST-line accessory.
