Looking for Ssr-25da Module? DC To AC SSR-25DA Solid State Relay Module 3-32 VDC /24-380VAC 25A is available at Zbotic with fast shipping across India.
Product Description:
This product is a DC to AC SSR-25DA Solid State Relay Module. It can control high-current AC loads with a low-voltage DC input. It has a 3-32V DC input range, a 24-380V AC output range, and a 25A current rating. A solid-state relay (SSR) is different from a mechanical relay because it has no moving parts. This makes it more reliable, faster, and longer-lasting than a mechanical relay. It also requires less power to operate.
This SSR uses a zero cross trigger control method, which means it switches on or off when the AC output crosses zero volts. This reduces noise and electromagnetic interference. The SSR has four screw terminals for easy wiring and a plastic cover for safety.
Features:
- Long service life and high reliability
- Reduced electromagnetic interference.
- Highly reliable, compact size designed to offer users maximum simplicity.
Package includes :
1 x DC To AC SSR-25DA Solid State Relay Module 3-32 VDC /24-380VAC 25A
DC To AC SSR-25DA Solid State Relay Module 3-32 VDC Overview
The DC To AC SSR-25DA Solid State Relay Module 3-32 VDC is designed to switch high-current AC loads up to 25 A using a low-voltage DC control signal. Ideal for reliable, silent operation, this SSR employs zero cross switching for minimal electrical noise and extended component life.

How to Use DC To AC SSR-25DA Solid State Relay Module 3-32 VDC
Connect a DC control voltage (3–32 VDC) to the input terminals (+ and –) and wire the output terminals in series with your AC load and supply (24–380 VAC). Mount the module on a heat sink or DIN rail, ensure proper wiring torque, and observe polarity when connecting the DC input. Power up the control circuit to switch the AC load with minimal noise and wear.

Frequently Asked Questions
What is the minimum DC input required to activate the SSR-25DA?
The SSR-25DA switches reliably with any DC input voltage between 3 V and 32 V. Below 3 V, the relay may not engage fully.
Can I switch inductive loads like motors or transformers?
Yes, the zero cross trigger reduces inrush current and EMI, making it suitable for many inductive loads. For heavy inductive loads, a proper heatsink and snubber circuit are recommended.
How should I mount and cool the SSR-25DA module?
Mount the relay on a DIN rail or panel using the built-in mounting holes. Attach a compatible heatsink if switching near the 25 A limit, and allow airflow around the module to maintain safe operating temperatures.
