Engineering Selection Recommendations

G7SA-2A2B-DC24 is the primary direct substitute for FGRMS22-24. This relay maintains electrical equivalence across all critical parameters including coil voltage, contact configuration, current rating, and switching voltage specifications. The G7SA-2A2B-DC24 is active and ROHS3 compliant, providing regulatory compliance advantages over the obsolete FGRMS22-24. The transition from screw terminal to PC pin termination requires circuit board or connector adaptation during implementation.

P7SA-10F serves as a supporting component for G7SA series relay integration in DIN rail environments. This socket accommodates G7SA relays and maintains screw terminal connectivity, facilitating mechanical compatibility with existing DIN rail installations. The P7SA-10F is active and ROHS3 compliant.

Selection between direct relay substitution (G7SA-2A2B-DC24) and socket-based integration (G7SA-2A2B-DC24 with P7SA-10F) depends on existing circuit architecture and termination requirements.

Frequently Asked Questions (FAQ)

Q: Can G7SA-2A2B-DC24 directly replace FGRMS22-24 in all applications?

A: G7SA-2A2B-DC24 matches all electrical specifications of FGRMS22-24, including coil voltage, contact configuration, current rating, and switching voltage. However, termination style differs: FGRMS22-24 uses screw terminals while G7SA-2A2B-DC24 uses PC pins. Circuit board or connector modifications are required for direct substitution.

Q: What is the purpose of P7SA-10F in relation to FGRMS22-24 replacement?

A: P7SA-10F is a DIN rail socket designed for G7SA series relays. It enables mechanical mounting of G7SA-2A2B-DC24 relays on DIN rail and provides screw terminal connectivity, supporting integration strategies where direct board-level replacement is not feasible.

Q: Are both substitute parts ROHS3 compliant?

A: Yes. Both G7SA-2A2B-DC24 and P7SA-10F are ROHS3 compliant, providing regulatory compliance advantages over the obsolete FGRMS22-24.

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

A: Substitution compatibility is determined by coil voltage (24VDC), contact form (4PST-2NO/2NC), contact current rating (6A), switching voltage (250VAC, 125VDC maximum), coil current (15 mA), coil resistance (1.6 kOhms), and operating temperature range (-40°C to 85°C).

Q: Does G7SA-2A2B-DC24 maintain the same release time as FGRMS22-24?

A: Yes. Both parts specify a 10 ms release time, ensuring equivalent switching response characteristics.
