Dual Relay SnipCard

The Dual Relay SnipCard (basic version) is equipped with two relay 36V – 2A max. In addition, there are two signaling LEDs to indicate the logic state of the corresponding relay.
The Dual Relay SnipCard is designed to make relays working in interlocked mode (optional) and to be able to insert a delay on the implementation of hardware control (optional), so you do not change the logic state of the relay in the event of a reset of the CPU board.
Alternatively to the Dual Relay SnipCard, in case you need a higher power device, in the space of the slot it’s possible to mount a single relay 10 A max. By mounting the single relay, on the terminal are available both the NO and NC contact.
