Vibro-meter VM600 PNR200-570-000-111 Relay Module

The Vibro-meter VM600 PNR200-570-000-111 is a 16-channel relay output module designed for the VM600 machinery protection and condition monitoring system. This module provides discrete alarm and trip outputs from measurement cards and system controllers, enabling direct connection to plant safety systems, PLCs, alarm annunciators, and other industrial control equipment.

Electrical Specifications

Each relay channel is rated for switching voltages up to 250 V AC and 30 V DC, with a maximum switching current of 5 A resistive load. The relay coils are energized based on alarm conditions received from the VM600 system controller, with each channel independently programmable for any combination of monitored parameters across all measurement cards in the rack. Status LEDs on the front panel provide clear visual indication of each relay state.

• Relay Channels: 16 independent form C (SPDT) relays

• Contact Rating: 250 V AC, 5 A; 30 V DC, 5 A (resistive)

• Contact Material: Silver alloy with gold flash

• Operate Time: 8 ms maximum

• Release Time: 4 ms maximum

• Mechanical Life: 10 million operations minimum

• Electrical Life: 100,000 operations at rated load

• Isolation: 1500 V RMS between coil and contacts

Configuration and Alarm Logic

Relay logic is fully programmable through the VM600 MPS software, allowing engineers to assign each relay channel to specific measurement parameters, alarm levels, and logic combinations. Configurable options include latching or non-latching operation, programmable time delays for alarm confirmation, and voting schemes for multi-channel trip decisions. The module supports both normally energized and normally de-energized relay configurations to accommodate different safety philosophies and fail-safe requirements.

Diagnostics and Reliability

The PNR200-570-000-111 incorporates comprehensive diagnostic features to ensure reliable operation. Front panel LEDs provide visual indication of each relay channel status. The module performs continuous monitoring of relay coil integrity and reports any detected faults to the system controller. In the event of a communication failure with the controller, the module can be configured to maintain last valid states or revert to predetermined safe states based on application requirements.
