SHINKAWA VM-5Y7-01/IS0 Relay Modul

Overview

The Shinkawa VM-5Y7 Relay Module is an output interface unit within the VM-5 series machinery protection system, converting monitor alarm states into hard-wired relay contacts for plant control and shutdown circuits. It provides four relay points covering DANGER1, ALERT1, DANGER2, and ALERT2 alarm signals from the connected VM-5 monitor modules.

Engineered for turbine supervisory instrumentation (TSI) and machinery protection applications, the VM-5Y7 delivers reliable, electrically isolated alarm outputs that integrate directly with PLC, DCS, and safety systems, providing the robust contact interface required for trip and annunciation duties.

Engineering & Design

The relay module is designed to plug into the VM-5 series instrument rack alongside monitor modules, with alarm contacts rated 250VAC 5A and 30VDC 5A for direct connection to external circuits. Each contact set is configured as normally energised or de-energised to match the alarm philosophy of the installation, and the plastic-sealed construction protects the relay mechanism from the rack environment.

With a contact life rated at 100,000 operations or more, the VM-5Y7 delivers long, dependable service life in continuous monitoring applications. The module operates from 0°C to 65°C with storage capability from -30°C to +85°C, consistent with the VM-5 series industrial specification.

Specifications

Relay modules are the final link between a machinery protection system and the plant trip and annunciation circuits, and the Shinkawa VM-5Y7 Relay Module is engineered to make that link dependable. Each VM-5Y7 provides four relay points that mirror the DANGER and ALERT states of the VM-5 monitors, giving the protection engineer a clean, hard-wired interface to the plant.

Alarm output reliability is essential, and the Shinkawa VM-5Y7 Relay Module provides it; Seven Star LLC supplies the Shinkawa VM-5Y7 Relay Module as a standard VM-5 series component.

The Shinkawa VM-5Y7 relay module provides the relay outputs for the alarm functions, and the Shinkawa VM-5Y7 relay module is the relay module of the vibration monitoring system.

The relay contacts of the VM-5Y7 are rated for the 250 V AC control circuits and are replaced as a complete module without soldering. The wiring of the relay outputs is made on the rear terminal block, and the module is labelled with the channel number for the annunciator mapping. The status of each relay is visible with the LED on the module front, which supports the point to point verification during the commissioning of the machine protection panel.

Why Seven Star LLC

Seven Star LLC supplies the Shinkawa VM-5Y7 Relay Module for machinery protection systems across the Gulf, with complete documentation and configuration guidance. Our specialists help confirm contact configuration and integration with your plant alarm and trip philosophy.

We support VM-5 system expansion, spares, and replacement programmes for turbine and compressor monitoring installations in power, oil and gas, and industrial facilities.

Interface Engineering

The 250VAC 5A and 30VDC 5A contact ratings of the VM-5Y7 are sufficient for direct connection of annunciator inputs, PLC cards, and interposing relays without additional buffering. The configurable normally energised or de-energised operation allows the module to match either energise-to-trip or de-energise-to-trip philosophies.

Rated for 100,000 operations or more, the relay contacts provide many years of service in continuous monitoring applications, and the plastic-sealed construction protects the internal mechanism from the rack environment.
