4 signal relay board, 4 wide voltage input, Multi-protocol card with 2 part horizontal connectors.
General purpose relay card with 4 opto-isolated, 12V operating, 120V, 3A signal relays and 4, 3V to 60V, AC/DC, opto-isolated voltage sensing inputs.
This card has 3 communication options:
This card also has 2 powering options:
- USB power
- External 5V DC with reverse polarity protection
Two LEDs indicate data transfers between your control hardware and the relay card for help with debugging and testing.
Each relay channel or voltage sensing input has its own LED to indicate status.
The card has been designed with future expansion in mind including access up to 6, 5V DIO channels connected to the main controller. The programming pins for the control processor are also available to enable re-purposing of the card by loading application specific software.
Nylon feet are fitted in each corner which will take self tapping screws. They can easily be removed to allow the cards to be mounted on pillars or stacked.
There is also a perspex cover available which offers general protection of the card and prevents accidental contact with any of the relay contacts or screw terminal connections. In addition, there is a DIN rail mount/cover option available.
These are industry standard relay boards and products. High quality equipment, for professional electronic automation, connectivity, and control.
