TTD Series Configurable Fault Annunciator for Engine Protection

Key Features

• 48 Configurable Sensor Inputs – Supports up to 48 monitoring channels that can be connected to normally open or normally closed sensors, enabling comprehensive monitoring of multiple engine and equipment parameters.
• Flexible Alarm and Shutdown Configuration – Each sensor input can be configured to trigger either an alarm notification or an automatic shutdown, allowing operators to customize protection strategies for critical equipment.
• Event History and Run Hour Tracking – Built-in memory records recent shutdown events and alarms along with associated run hours, helping maintenance teams quickly diagnose faults and review equipment performance history.
• Modbus RTU Communication – Equipped with RS232 or RS485 communication interfaces that support Modbus RTU protocol for seamless integration with PLCs, SCADA systems, and remote monitoring platforms.
• Integrated Tachometer Monitoring – Optional tachometer functionality enables engine speed monitoring with configurable overspeed and underspeed protection for improved operational safety.
• Built-in Test Mode – Allows technicians to verify sensor circuits and system functionality without triggering a shutdown condition, simplifying maintenance and system testing.
• Rugged Industrial Design – Engineered for demanding environments including marine, oil & gas, and industrial installations where reliability and equipment protection are critical.

Typical Applications

This direct mount temperature gauge with adjustable limit switch is widely used in applications requiring both temperature indication and automatic protective action.

The TTD Series configurable fault annunciator is widely used in industrial and marine environments where reliable monitoring and shutdown protection are required to safeguard critical equipment.

• Marine Engine Monitoring – Provides fault indication and shutdown protection for propulsion and auxiliary engines operating in commercial vessels and marine installations.
• Oil and Gas Equipment Protection – Monitors compressors, pumps, and field equipment in upstream and midstream operations where continuous operation and safety are essential.
• Industrial Pump Systems – Detects abnormal conditions such as overheating, pressure faults, or lubrication issues to prevent pump damage and costly downtime.
• Gas Compressor Monitoring – Enables early fault detection and automatic shutdown to protect compressors used in gas processing and transmission facilities.
• Generator and Power Systems – Helps monitor engine-driven generators and power equipment by detecting operational faults and triggering alarms or shutdown when necessary.
