Omron MY2IN-CR-GS-R AC110/120 General Purpose Relay Guide
The Omron MY2IN-CR-GS-R AC110/120 general purpose relay is an 8-pin plug-in relay designed for AC control circuits. It features DPDT contacts, a 110/120 VAC coil, mechanical and LED indicators, coil surge absorption, and a lockable push test button. Omron Europe lists these features for this exact model, making it one of the more service-oriented versions in the MY-GS-R lineup. :contentReference[oaicite:6]{index=6}
Technical Overview
This relay is designed for applications where visual feedback, test functionality, and coil protection are important. The LED indicator helps confirm coil energization, while the mechanical indicator shows contact operation. The lockable push test button supports controlled testing during commissioning or troubleshooting, provided safe working procedures are followed.
The DPDT contact arrangement allows one AC coil signal to switch two independent circuits. This is useful in industrial control panels, machine control, HVAC systems, lighting control, access systems, and auxiliary switching networks.
AC Coil and Relay Behavior
The AC110/120 coil rating makes this relay suitable for panels using 110 or 120 VAC control power. Omron’s related MY2 AC110/120 data lists coil ratings for 110 VAC and 120 VAC at both 50 Hz and 60 Hz, with DPDT contact form, silver contacts, and plug-in terminals. :contentReference[oaicite:7]{index=7}
The built-in coil surge absorption is an important feature because relay coils can create electrical noise or voltage transients when energized or de-energized. Integrated suppression helps reduce stress on surrounding control components and can support cleaner panel operation.
Why the Test Button Matters
The lockable push test button is helpful during panel commissioning and maintenance. It allows a technician to manually operate the relay for circuit verification. This can speed up functional checks, but it must be used carefully because manually forcing a relay can energize connected loads.
Common Applications
The Omron MY2IN-CR-GS-R AC110/120 relay is well suited for AC control panels, industrial machines, building control systems, pump control cabinets, HVAC switching, access control circuits, and relay logic panels. Its combination of LED indication, mechanical indication, surge absorption, and test operation makes it especially useful in environments where diagnostics matter.
Selection Guidance
Before using this relay, confirm that the control voltage is 110/120 VAC, the socket matches the 8-pin configuration, and the load connected to each contact is within the relay’s permitted rating. For inductive loads, engineers should also evaluate additional protection and contact life expectations.
