Modules RY1 and RY2

Modules RY1 (non-latching) and RY2 (latching) are NAI’s latest generation Relay Modules. They provide multichannel, signal switching capabilities up to 220 VDC / 250 VAC @ 2 A maximum (cumulative maximum switching power 60 W / 62.5 VA per channel).  These modules are used in our multifunction embedded boards and SBCs, and also for testing and non-critical embedded applications.

These two mechanical relay-interface modules feature four individual single-pole, user SPDT Form C (changeover/break-before-make type) relays (channels). Each channel has a common input terminal (C), a normally closed output terminal (N/C), and a normally open (N/O) output terminal. The channel either energizes or de-energizes the relays (close or open) so that the signal provided on (C) may be switched/directed to either the (N/C) or (N/O) terminals.

The second set of pole contacts is used for the Background Built-In-Test (BIT) status. Interrupts can be enabled/configured for each channel to indicate if a BIT fault (state of secondary set of contacts does not match command) occurs. Internal debounce circuits for each channel provide the required time delay to eliminate false signals resulting from contact bounce commonly experienced with mechanical relays and switches.

RY1 Relay Non-Latching Module

The relays on this module remain de-energized or in the "reset" position until commanded to the "set" position. The contacts remain in the "set" position until commanded to the "reset" position. A board level reset is issued if power is removed from the board or the module.

RY2 Relay Latching Module

The relays on this module use magnetic latching to assure that once a relay channel is "set" or "reset," the channel will remain at the last commanded position, even if power is removed from the board or the module.
