SpeedSys T11 – 1‑Channel Speed Monitor and Switch with Display

Functional replacement for Jaquet T411 and T412

The SpeedSys T11 is a modern, single‑channel speed monitoring and switching device designed to replace legacy Jaquet T411/T412 units. It provides accurate speed measurement, relay output for switching or alarm functions, and an integrated display for local monitoring.

Key Features

  • 1‑Channel Speed Monitoring – Measures rotational speed from a single sensor input.

  • Integrated Display – Real‑time speed readout for local monitoring and verification.

  • Sensor Compatibility – Works with 2‑wire passive (VR/MPU) and 3‑wire active (Hall‑effect/proximity) sensors.

  • Analog Output – High‑accuracy 4–20 mA output for PLC or control system integration.

  • Relay Output – 1× SPDT relay for overspeed/underspeed or alarm indication, fast response under 4 ms.

  • Diagnostic Functions – Monitors sensor health, detects open‑ or short‑circuits, and provides status indication.

  • Modern Configuration – Fully adjustable limits and parameters using onboard controls or digital interface.

  • Compact Industrial Design – Rugged housing for panel mounting, low power consumption, and wide operating temperature range.
