The PS710A-1A and PS710AL-1A are solid state relays with GaAs LEDs on the input side and MOS FETs on the output side. It is suitable for PLC applications due to its large continuous load current and low on-state resistance.
The NEC PS710A-1A and PS710AL-1A are solid‑state relays that combine a GaAs LED input with a MOSFET output. They are offered in a 6‑pin DIP package (PS710A‑1A) and a surface‑mount version (PS710AL‑1A) and are designed for PLC and other control applications.
Key specifications include a low on‑state resistance of 0.1 Ω, a continuous load current of 1.8 A, and an isolation voltage of 1500 V. The devices are UL, BSI and CSA approved and are suitable for measurement and FA equipment.
