Bitronics VTAIE1 Three Phase Voltmeter Module

Bitronics VTAIE1 Three Phase Volt Meter is a panel‑mounted voltmeter module in the Bitronics TriPlex family that reads phase voltages on a four‑wire, three‑phase system. It accepts universal voltage inputs in the 20–280 V DC or 55–200 V AC range, enabling direct connection to common low‑voltage DC and AC power circuits without external scaling. In a four‑wire configuration, the VTAIE1 measures phase voltages for A, B, and C (phase‑to‑neutral); a companion VTAIE2 covers the three‑wire (phase‑to‑phase) configuration. The module is designed for use with Bitronics faceplate legends, with options such as KVOLTS/A‑B/C and KVOLTS/1/2/3 to label the voltages on the panel. As part of Bitronics’ TriPlex/PowerPlex monitoring solutions, it provides reliable voltage readings for each phase in industrial power‑monitoring panels. Distributor listings note that the VTAIE1 has been discontinued by the manufacturer, with remaining stock typically available through secondary channels.
