EMAS SSRP1DA040 solid state relay with 40 A output rating, 4–32 V DC control input and 24–320 V AC load switching for industrial automation applications.
£47.26
The EMAS SSRP1DA040 is a compact single-phase solid state relay (SSR) designed for reliable electronic switching of AC loads in industrial automation, heating control and electrical control panel applications. With a 40 A load current rating and DC control input, it provides fast, silent and long-life switching without mechanical contacts.
Featuring a 4–32 V DC control input and a 24–320 V AC load voltage range, the SSRP1DA040 enables PLCs, temperature controllers and automation equipment to control AC loads efficiently. Its panel mounting design, LED indication and finger-safe terminals support straightforward installation in industrial systems.
The EMAS SSRP1DA040 uses solid state semiconductor switching technology to provide dependable operation for applications requiring frequent switching cycles. With no mechanical moving parts, it helps reduce wear and improve operational reliability compared with traditional electromechanical relays.
Solid state relays provide fast and reliable switching by using semiconductor technology instead of mechanical contacts. The EMAS SSRP1DA040 is designed for applications requiring high switching frequency, reduced maintenance and quiet operation.
Its DC control input makes it suitable for integration with PLC outputs, temperature controllers and industrial automation equipment, while the AC output stage supports a wide range of electrical loads.
