Omron MY2IN-GS DPDT Relay with Latching Lever and LED

MY2IN-GS: 2-pole relay with a latching lever for circuit testing

The Omron MY2IN-GS is a DPDT miniature power relay that adds a manual latching lever to the standard MY2N-GS body. The lever lets a technician force the contacts closed, momentarily or locked, without energising the coil, which is invaluable when proving a relay sequence. Seven Star LLC supplies the MY2IN-GS in Oman and the GCC as an independent supplier in Muscat. Details follow below.

• MY is the miniature plug-in power relay series.
• 2 means two poles (DPDT) with an 8-pin footprint.
• I means a latching lever is fitted.
• N means a LED operation indicator and built-in mechanical indicators.
• GS is the series suffix; the datasheet ordering list adds -R and the coil voltage.

The lever colour identifies the coil: red for AC and blue for DC, and the LED is red for AC and green for DC.

MY2IN-GS technical specifications

Specifications follow the MY-GS datasheet. The lever should be operated with an insulated tool, as the datasheet describes pressing the yellow button for momentary operation.

How MY2IN-GS works and what the indicators show

The relay works like any plug-in electromechanical relay: coil current moves an armature that changes the contact state. The addition of a lever offers two manual positions. Slid one step, the lever exposes a yellow button which can be pressed to operate the contacts temporarily; slid two steps, the contacts lock in the operated position.

This design helps commissioning teams: instead of forcing signals or jumpering coil circuits, they can operate the relay by hand and observe the effect on the rest of the circuit. Care is needed, as a locked lever leaves the circuit energised regardless of the coil, so a locked relay should be recorded and released before handover.

Coil ratings for MY2IN-GS

Coil options for MY2IN-GS match those of the MY2N-GS. Choose the type that matches the control supply, and note that lever and LED colours depend on the coil type.

AC coil data from the datasheet (rated current measured at 23°C):

DC coil data from the datasheet (values in brackets are for models with LED indicators):

Must-operate voltage is 80% of rated voltage maximum for AC coils (30% minimum must-release) and the same 80% maximum for DC coils with 10% minimum must-release. Maximum voltage is 110% of rated. For specified characteristics, apply the rated voltage to the coil.

Sockets and related parts for MY2IN-GS

MY2IN-GS fits the same 8-pin sockets as other MY2 types. When used with a PCB-terminal socket such as PY08-02, the datasheet notes that a PYC-P mounting bracket should be checked for compatibility. It is the right relay where test access matters; for fixed circuits the cheaper MY2N-GS is enough.

Sockets are ordered separately. The datasheet also mentions the PYC-A1 and PYC-P retaining parts for joining socket and relay, and notes that a relay with a latching lever and a PCB-terminal socket need the PYC-P mounting bracket to be checked first.

Selection and ordering checklist for MY2IN-GS

Settle the following before requesting a quotation for MY2IN-GS.

• Confirm that a manual test lever is wanted and that site rules allow it on that circuit.
• Choose AC or DC coil and the voltage.
• Check load against 10 A at 250 VAC and inductive ratings.
• Select an 8-pin socket, noting PCB socket restrictions with the lever.
• Decide on diode or CR suppression versions if required (MY2IN-D1/D2-GS or MY2IN-CR-GS).
• Plan a procedure to ensure levers are returned to normal after testing.

Installation, commissioning and maintenance of MY2IN-GS

Install the MY2IN-GS as for any MY2 relay. Do not leave the lever in the locked state after testing.

• Use an insulated tool to press the yellow button.
• Record any relay left locked on purpose.
• Check coil voltage matches the colour code on the lever.
• Verify contact motion with the mechanical indicator.
• Keep a few spares since test levers can be mishandled during frequent testing.

Typical MY2IN-GS applications in Oman and the GCC

Latching-lever relays are favoured in shutdown and interlock panels where sequences must be proven without live plant: pump auto-start logic, burner management repeats, MCC control circuits and gas-turbine auxiliary panels. In Oman and the GCC they appear in plant maintenance specifications that demand testability.

In regions where plant turnaround time is expensive, the ability to prove circuits quickly pays back. The lever must nevertheless be controlled by permit-to-work practice.
