Vibro-Meter VMF-RLC16-V111 200-570-101-015 & 200-570-000-111 16-Channel Relay Logic Cards: Overview and Technical Specifications
Brand and Model Identification
The VMF-RLC16-V111 200-570-101-015 and 200-570-000-111 are high-reliability 16-channel Relay Logic Cards (RLC16) manufactured by Meggitt Vibro-Meter (now part of Meggitt Sensing Systems), designed specifically for integration with the VM600 series of machinery protection and condition monitoring systems. These robust relay output modules serve as critical components for translating monitoring system alarms and control signals into physical relay actions, enabling direct interface with industrial control systems, shutdown mechanisms, and alarm notification devices across various industrial sectors. The two model numbers represent variations of the same RLC16 card, with the 200-570-101-015 being a specific version of the VMF-RLC16-V111 variant, while 200-570-000-111 is the standard RLC16 card configuration.
General Specifications
Both VMF-RLC16-V111 cards operate on a 24V DC power supply (standard for industrial automation systems) and feature a robust construction suitable for harsh industrial environments. They support live insertion and removal within the VM600 rack, allowing for hot-swapping capabilities without system shutdown, minimizing operational downtime. The modules have a typical weight of 0.34 kg (340g) and compact dimensions of 100mm x 233mm x 35mm (WxHxD), making them space-efficient for installation in standard VM600 racks. They are designed to be compatible with VM600 IOC series input/output interface cards, which provide the necessary terminal connections for external devices.
Physical Dimensions and Weight
Dimensions: 100mm (width) × 233mm (height) × 35mm (depth) for the card itself; designed for standard VM600 rack mounting
Weight: 0.34 kg (340 grams) for the RLC16 module alone
Form Factor: VM600 rack-mountable module, occupying 1 slot in the VM600 system rack
Mounting: Card-edge connector for secure integration with VM600 backplane bus
Front Panel: Features LED status indicators for power and system communication status
Key Features
The VMF-RLC16-V111 cards offer a comprehensive set of features for industrial machinery protection and condition monitoring applications:
Equipped with 16 individually configurable Single-Pole Double-Throw (SPDT) relays providing versatile switching capabilities for alarm and control functions
Each relay is associated with 3 terminals on a screw-terminal connector accessible at the rear of the VM600 rack for easy wiring connections
Relays are controlled by open-collector drivers under software control via the VM600 backplane bus
Jumpers on the RLC16 card allow the selection of relay normally energized (NE) or normally de-energized (NDE) states to accommodate different safety requirements
Provides additional relay capacity beyond the standard 4 relays on IOC4T and IOC8T cards, making it ideal for complex machinery protection schemes requiring multiple alarm outputs
Supports VM600 system safety-line to drive all system relays to a safe state in case of critical system faults
Compatible with VibroSight® software for configuration, monitoring, and diagnostic purposes
Designed for use in machinery protection systems (MPS) and condition and performance monitoring systems (CMS)
Hot-swappable design allows for module replacement without system shutdown, ensuring continuous operation during maintenance
Input Specifications
The VMF-RLC16-V111 cards receive control signals from the VM600 system backplane bus for relay operation:
Backplane bus input: Receives control signals from VM600 CPU modules (VMF-CPUM) and monitoring cards (MPC4, AMC8, CMC16) via the VM600 open-collector bus (OC Bus)
Control inputs: Digital signals from monitoring cards indicating alarm conditions (warning, alarm, shutdown) or other system events requiring relay activation
Safety-line input: Receives system safety-line signal to drive all relays to a preconfigured safe state in case of critical system failure
Configuration inputs: Jumper settings for selecting NE/NDE states for each relay, allowing hardware-based configuration of relay behavior
Output Specifications
The VMF-RLC16-V111 cards provide versatile relay outputs for integration with external industrial systems:
16 SPDT relay outputs: Each relay provides three connection points (common, normally open, normally closed) for flexible switching configurations
Relay contact ratings: Typically rated for 250V AC/30V DC at 5A resistive load, ensuring compatibility with most industrial control circuits
Relay operation: Each relay can be individually configured to respond to specific alarm conditions or system events via VibroSight® software
Status outputs: Front-panel LED indicators for power and communication status, providing visual confirmation of module operation
Safe state operation: All relays can be driven to a safe state via the VM600 system safety-line, ensuring machinery protection even during system faults
