Product Overview
Crydom PS-240 is a compact, PCB-mount solid state relay in a SIP (Single In-line Package) through-hole form factor. It switches AC loads up to 240VAC at 2A steady state using a 3-32VDC control signal — no moving parts, no mechanical wear, no arcing. Zero-cross switching reduces EMI, making it well suited for resistive loads such as heaters. Opto-isolated input separates the control circuit from the load circuit.
Key Features
- Output: 240VAC maximum load voltage
- Load current: 2A steady state
- Control input: 3-32VDC
- Switching: Zero-cross (reduces EMI on resistive loads)
- Package: SIP — Single In-line Package, through-hole PCB mount
- Isolation: Opto-isolated input-to-output
- AC output only — not suitable for DC load switching
Applications
- Heater element control in industrial and HVAC systems
- PLC and microcontroller output switching for 120V/240V AC loads
- Lighting control and lamp switching
- Maker and prototyping projects requiring logic-level (3.3V/5V) control of mains voltage
- Packaging machinery and automation panel builds
Frequently Asked Questions
What control voltage does the PS-240 require?
3-32VDC. This range covers 3.3V and 5V logic directly, making it compatible with Arduino, Raspberry Pi, and most PLC digital outputs without a separate driver circuit.
Will this relay switch DC loads?
No. The PS-240 is an AC output relay and uses zero-cross switching. It will not turn off when used on a DC load. Use only on AC circuits.
Can it handle inductive loads like motors or solenoids?
Rated at 2A steady state. Inductive loads produce high startup surges that may exceed this rating. Verify your application's peak surge current against the datasheet before use. Not confirmed — check Crydom datasheet for peak surge rating.
What is included with this unit?
The PS-240 relay only. No documentation or mounting hardware included.
Crydom's PS series remains a trusted choice for compact PCB-mount SSR applications. Verify lead condition and confirm thermal requirements for your board layout before soldering.
