Product Overview
Engineered for board-level power switching, this 4-pin SIP module pairs optical isolation with an internal MOSFET output stage to control high-current direct current circuits. Handling loads from 0 to 60 VDC at up to 20 A with appropriate heat sinking, it provides bounce-free switching without mechanical contact wear. A 3.0 to 10.0 VDC control threshold allows direct interfacing with microcontrollers, PLC digital outputs, and standard low-voltage logic.
Key Features
- Load voltage range of 0 to 60 VDC
- Continuous load current rating of 20 A DC with appropriate heat sinking
- Control input voltage range of 3.0 to 10.0 VDC
- Maximum on-state resistance of 0.0033 ohms (3.3 mΩ)
- 2,500 Vrms input-to-output optical isolation
- 4-pin through-hole SIP package configuration
- SPST-NO (1 Form A) DC switching architecture
Applications
- Direct DC motor switching and solenoid valve actuation from microcontrollers
- High-amperage bench power supply output switching and programmable load benches
- Automotive 12V and 24V auxiliary accessory power switching without mechanical contact bounce
- Battery-backup cutover and renewable energy DC distribution panels
Frequently Asked Questions
What control voltage does this relay require to switch on?
The input control range is 3.0 to 10.0 VDC, switching on cleanly at 3.0 VDC and off below 1.0 VDC.
Can this relay switch AC mains or inductive AC loads?
No. The CMX60D20 uses an internal MOSFET output designed strictly for DC loads up to 60 VDC. Polarities are indicated on pins 1 (+) and 2 (-).
What distinguishes the CMX60D20 from lower-rated CMX series models like the CMX60D10?
The CMX60D20 carries a 20 A continuous load rating and 3.3 milliohm on-state resistance, doubling the current handling capability of the 10 A variant in the same SIP-4 board footprint. Each piece costs less as the order grows - see the price-break table on this page.
