Megger TM200 Digital Timer

Overview

The Megger TM200 is a rugged, compact and precise digital timer designed for a broad range of electrical timing tasks, from relay pick-up and drop-out measurements to general contact and switch timing in the field or on the bench. Housed in a small, portable enclosure, it combines laboratory-grade timing accuracy with the durability needed for everyday industrial use, making it a practical tool for protection, maintenance and commissioning engineers.

The TM200 measures the time between a start and a stop event with 1 ms resolution across a 0 to 999.999 second range and an accuracy of ±0.02% plus one digit. Both the start and stop inputs accept either dry-contact (potential-free) or voltage signals, so the timer can be triggered directly from relay contacts or from applied AC or DC control voltages without additional interfacing. This flexibility, together with its simple operation and mains adapter supply, lets the TM200 slot into almost any timing application.

Key Features

• Precise single-channel timing from 0 to 999.999 s with 1 ms resolution and ±0.02% + 1 digit accuracy.
• Start and stop inputs each accept dry-contact or voltage sensing for maximum triggering flexibility.
• Voltage sensing on AC and DC control signals; contact sensing distinguishes closed (0–1 kΩ) from open (≥4 kΩ) contacts.
• Rugged, compact and lightweight design (about 1 kg) for easy field portability.
• Broad application range across relay testing, contact timing and general electrical measurements.
• Simple mains-adapter power supply with wide 100–240 V AC input.

Applications

• Measuring relay operate and release times in protection and control systems.
• Timing of contactors, switches, contacts and other electromechanical devices.
• Commissioning and routine maintenance testing where a precise, portable timer is required.
• General-purpose electrical timing on the bench or in the field.

What’s in the Box

• TM200 digital timer.
• Mains power adapter (100–240 V AC input, 5 V DC output).
• Test leads for start/stop contact and voltage sensing.
• Carrying case and user documentation.
