 2, 4, 6 or 8 Relay Card with wide voltage control. Available in 12VDC or 24VDC These would have to be the most versatile relay cards on the market. Each relay can be operated by TTL levels, NPN and PNP open collector or 0 to 12V(0 to 24V if using 24VDC relays). Each relay has two inputs, marked LO and HI. As the names suggest a low on the LO input will operate the relay. Similarly a high on the HI input will also operate the relay. Specifications: Operating Voltage 12VDC (or 24VDC) Input low voltage (LO) 0 - 0.8V Input high voltage (HI) 2.4 - 12V (or 24VDC) We have operated these relays from an old style TTL 7404 Hex Inverter which have less drive capacity than the newer HC and HCT types. The inverter could operate the relay with both a low and a high output signal. But what is more important was that the High voltage dropped from 4V to 3.5V showing the output still had capacity to drive other TTL devices The relays
used are Goodsky RW-SS-122D Dimensions
