Description
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.
