Vibro-meter VMF RLC16 Relay Output Module

The Vibro-meter VMF RLC16 is a high-density relay output module designed for the VMF series condition monitoring system. This module provides discrete alarm and trip outputs for machinery protection applications, enabling direct connection to plant safety systems, PLCs, and alarm annunciators.

Relay Specifications

The module features 16 independent form C (SPDT) relay channels, each providing normally open and normally closed contacts. Relays are rated for industrial control applications with high contact reliability. The contact design utilizes silver alloy with gold flash for consistent performance across the operational lifetime, suitable for switching both AC and DC loads.

• Relay Channels: 16 independent form C relays

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

• Contact Material: Silver alloy with gold plating

• Operate Time: 8 ms maximum

• Release Time: 4 ms maximum

• Mechanical Life: 10 million operations

• Electrical Life: 100,000 operations at rated load

• Isolation: 1500 V RMS coil to contacts

Alarm Configuration

Relay logic is fully programmable through the VMF system software, allowing each relay to be assigned to any combination of monitored parameters across the rack. Configurable features include latching or non-latching operation, programmable time delays, 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.

Diagnostic Capabilities

Front panel LEDs provide clear visual indication of each relay channel state, with distinct colors for energized and de-energized conditions. The module includes continuous coil integrity monitoring, reporting any relay failures to the system controller. In the event of communication loss with the system controller, each relay can be configured to maintain its last state or revert to a predetermined safe state based on application requirements.
