3515| Triconex |Pulse Totalizer Input (PTI) Module

Description

The 3515 Pulse Totalizer Input (PTI) Module, part of the TMR series, offers 32 independent 31-bit counters for precise measurement from active-flow or per-unit sensors. It supports hot-swap functionality with a hot-spare module and provides ongoing diagnostics for each channel.

Features

• 32 individual 31-bit counters
• Three isolated input channels
• Continuous diagnostics and fault detection
• Hot-swap capability with a hot-spare module
• Counter overflow indication via negative integer count
• Point isolation at 1500 VDC minimum
