SHINKAWA VM-5Y7-01/IS0 Relay Module
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.

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.

Matching the VM-5Y7 Suffix Code
Shinkawa relay modules are supplied in different versions, and the suffix after the base model (for example -01 and the option code that follows) defines the configuration. Read the full model code from the label on the installed module and compare it with the rack drawings. Record which monitor modules the relay module serves, how each relay is wired, and whether each contact works normally energised or de-energised in your plant. A module that looks the same but has a different option code may not behave the same way in your trip circuit.
Commissioning and Loop Checks
Relay outputs carry machine trips, so every point should be tested after a module change. Coordinate with operations and apply the bypasses your procedures require. A typical check sequence is:
- confirm the wiring on the rear terminal block against the loop drawings;
- force or simulate ALERT and DANGER states on the associated monitor module;
- check each relay LED and verify the change of state at the DCS, PLC, annunciator or trip relay;
- confirm the fail-safe behaviour by checking what the contacts do on power loss;
- record the results and remove bypasses only after all points pass.
Maintenance and Troubleshooting
- Alarm in the monitor but no signal in the DCS: check the relay LED first; if it has changed state, look for wiring, fuse or interposing relay problems downstream.
- Relay LED does not change on alarm: check the alarm assignment and logic settings in the monitor module before replacing the relay module.
- Intermittent contact behaviour: contacts switching loads beyond their rating or inductive loads without suppression wear faster; use interposing relays for larger loads.
Include relay outputs in your periodic proof testing of machinery protection trips, and keep a record of each module’s configuration.
Use in Oman and the GCC
VM-5 systems protect steam and gas turbines, compressors and generators across the region’s power, desalination and oil and gas plants. Because a failed relay module can take several trip paths out of service, many sites keep one tested spare per rack type.

Where Shinkawa vibration monitoring is used
Shinkawa systems measure shaft vibration, axial (thrust) position, speed, phase reference and bearing temperature on steam turbines, gas turbines, generators, compressors, pumps and fans. The monitors provide alarm and trip relays for machine protection and buffered signals for analysis. In the GCC they are met mainly in power stations, desalination plants, refineries and petrochemical units with Japanese or Korean machinery packages.Ordering Shinkawa parts: what we need
Shinkawa model codes are long and every field counts. A monitor such as VM-5K-411512-000-000-111-0/IS0/EX5 defines input type, range, options and suffix codes, so please copy the complete string from the module label, including everything after the slashes. For sensors, send the VL or FK model code, probe tip diameter, cable length and the matching driver or converter model, since probe, extension cable and driver work as a calibrated set. A serial number and a photo of the label help us confirm the item in the manufacturer's documentation. Where a model is no longer produced, we propose the successor the manufacturer names.Browse Shinkawa products by category: Vibration.
