SSR-25DA Solid State Relay – 25A DC to AC SSR Module for PID Temperature Control
SSR-25DA Solid State Relay – 25A DC to AC SSR Module for PID Temperature Control
The SSR-25DA Solid State Relay is a highly reliable DC-to-AC switching module designed for industrial automation, PID temperature control systems, and AC load management. It allows a DC input signal (3–32VDC) to control an AC output load (24–380VAC) with a maximum switching capacity of 25A. This silent, fast-switching relay features optoisolated inputs, eliminating noise and mechanical wear common in traditional relays.
⚙️ Key Features:
- ⚡ 25A Load Capacity – Handles high-voltage AC loads with stable switching
- 🔌 DC to AC Switching – Accepts 3–32VDC control input, switches 24–380VAC load
- 🔇 Silent Operation – No moving parts, no clicking noise, longer lifespan
- 🔧 Fast Response Time – Ideal for applications requiring rapid switching like PID temperature control
- 🧱 LED Indicator – Displays input signal status at a glance
- 🛠️ Panel Mount Design – Easy installation with screw terminals and solid construction
📦 Specifications:
- Model: SSR-25DA
- Input Control Voltage: 3–32VDC
- Output Load Voltage: 24–380VAC
- Rated Output Current: 25A
- Trigger Current: ≥7.5mA
- Output Type: Zero-cross AC switching
- Isolation: Optical isolation for protection
- Mounting: Panel mount with heat sink support recommended
💡 Applications:
- PID temperature controllers (heaters, ovens)
- AC motor control
- Lighting systems
- Industrial machinery automation
- Home appliance control systems

📌 Providing your diagram is essential so we can give you an accurate and fair quotation.
PCB Layout & Design Requirements
To ensure quality and accuracy, please note the following:
- All schematics must be clear, complete, and properly labeled
- Specify:
- Board dimensions (if available)
- Number of PCB layers
- Preferred components or footprints (if any)
- Hand-drawn, unclear, or incomplete schematics are not accepted
- Rush or urgent requests may incur additional charges
What’s Included in the Design Package
Each completed project includes the following deliverables:
