FGRMS22-24-LED Equivalent & Substitute Parts

Part Overview

The FGRMS22-24-LED is a 24VDC relay manufactured by Omron Automation and Safety, configured as a 4PST (4-pole, single-throw) device with 2 Form A and 2 Form B contacts. This relay is designed for industrial control applications requiring simultaneous switching of multiple circuits at 6A contact rating. The product is currently obsolete, making identification of functionally equivalent alternatives essential for system maintenance, repair, and redesign applications.

Engineering Selection Recommendations

The G7SA-2A2B-DC24 is the primary direct substitute for the FGRMS22-24-LED relay. Both components share identical electrical specifications including 24VDC coil voltage, 4PST contact configuration, 6A contact rating, and 10 ms release time. The G7SA-2A2B-DC24 is currently in active production status with ROHS3 compliance and REACH Unaffected classification, providing long-term availability and regulatory compliance advantages over the obsolete FGRMS22-24-LED.

The primary difference between these relays is mounting and termination approach. The FGRMS22-24-LED uses DIN Rail mounting with screw terminals, while the G7SA-2A2B-DC24 employs socketable through-hole mounting with PC pin termination. For applications requiring DIN Rail screw terminal configuration, the G7SA-2A2B-DC24 can be paired with the P7SA-14F-ND DC24 relay socket, which provides 14-position DIN Rail mounting with screw terminal connectivity compatible with G7SA series relays.

Selection between direct relay substitution and socket-based configuration depends on existing circuit board layout and installation infrastructure. Both approaches maintain full electrical equivalence to the original FGRMS22-24-LED specification.

Frequently Asked Questions (FAQ)

Q: Can the G7SA-2A2B-DC24 directly replace the FGRMS22-24-LED in existing applications?

A: The G7SA-2A2B-DC24 provides complete electrical equivalence with identical coil voltage, contact configuration, current rating, and switching characteristics. However, mounting and termination differences require mechanical adaptation. Direct socket-to-socket replacement is not possible without circuit board modification or use of an intermediate relay socket.

Q: What is the purpose of the P7SA-14F-ND DC24 socket in relation to relay substitution?

A: The P7SA-14F-ND DC24 is a 14-position DIN Rail relay socket designed for G7SA series relays. It provides screw terminal connectivity and DIN Rail mounting, enabling G7SA-2A2B-DC24 relays to be installed in applications originally designed for DIN Rail mounted relays with screw terminals. This socket facilitates mechanical compatibility without requiring circuit board redesign.

Q: Are there any compliance or regulatory differences between the FGRMS22-24-LED and G7SA-2A2B-DC24?

A: The G7SA-2A2B-DC24 carries ROHS3 compliance and REACH Unaffected status, providing current regulatory alignment. The obsolete FGRMS22-24-LED does not carry these certifications. Both components share EAR99 ECCN classification and identical MSL ratings. For new designs or systems requiring current compliance documentation, the G7SA-2A2B-DC24 is the appropriate selection.

Q: What are the key electrical parameters that determine substitution compatibility?

A: Substitution compatibility is determined by coil voltage (24VDC), contact configuration (4PST-2NO/2NC), contact current rating (6A), switching voltage capability (250VAC, 125VDC), coil current (15 mA), and operating temperature range (-40°C ~ 85°C). All substitute parts must maintain these specifications within the defined tolerances.

Q: Can the G7SA-2A2B-DC24 be used in high-temperature or low-temperature environments?

A: The G7SA-2A2B-DC24 maintains full operational specifications across the -40°C ~ 85°C temperature range, identical to the FGRMS22-24-LED. No derating or special considerations are required within this range.
