Description
The ProvibTech PT2060/53 PT2060/53-A0 O-SPEED Over-speed Module is a rack-based process signal and relay module engineered for overspeed detection and machinery protection. It features 1 channel per card and is powered through an internally converted rack power supply with approximately 8.0W typical consumption per module. The design supports high-precision signal processing from proximity probes and magnetic pickups.

The module accepts an input voltage range of +10 to -24VDC with input impedance greater than 20KΩ. It supports frequency input up to 10 kHz and can handle 1 to 255 events per revolution, with a maximum full-scale speed range of 60,000 RPM. The ProvibTech PT2060/53 PT2060/53-A0 O-SPEED Over-speed Module delivers accuracy depending on speed range, from ±0.1 RPM at low speed to 0.01% at high-speed conditions.

For signal conditioning, the module provides a -24VDC current-limited transducer power supply with less than 50mA per channel. Trigger thresholds can be configured from -17VDC to -3VDC, with selectable hysteresis between 0.5 and 2.5V. Alarm response is fast, with delay times under 30ms for frequencies above 300Hz, ensuring rapid protection response.

The ProvibTech PT2060/53 PT2060/53-A0 O-SPEED Over-speed Module includes LED indicators for OK/IO status (green), alarm status (red), and bypass mode indication. It also provides additional monitoring outputs such as speed, zero speed, reverse rotation protection, vibration, axial/thrust position, eccentricity, and differential expansion. These functions are assigned according to channel configuration, with channel 3 and 4 offering extended measurement capabilities.

When used in redundancy systems, the module requires a redundant power supply and a redundant PT2060/43 relay module. In such configurations, only channel 1 is active. The module also supports Modbus communication and configuration software access, allowing retrieval of alarm history, module status, and system events. Rack installation requires four slots for a complete overspeed protection setup.
