Eight 24VDC Relay Card on DIN Rail

Eight 24VDC Relay Card on DIN Rail
Eight 24VDC Relay Card which can mount on DIN Rail 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 12VDC. 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.

Operating Voltage 24VDC
Input low voltage (LO) 0 - 0.8V
Input high voltage (HI) 2.4 - 24V

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

Each single pole changeover relay contacts SPDT will switch 10A/24VDC , 10A/50VAC
Coil Resistance for the relays is 1600ohm(24V)

Current consumption for 2 relay card (24V)
All relays off 4mA
One relay on 24mA
Two relays on 44mA
A LED shows the state of each relay
. The Relay Cards are available in 12VDC or 24VDC
Four 3.5mm holes in each corner allow easy mounting on a panel
