About the KV-E4XR
The KV-E4XR has four (4) inputs and four (4) relay outputs device by Keyence. The KV-E4XR has a nineteen (19) V minimum ON voltage. The maximum OFF current for the KV-E4XR is two (2) mA. The input time constant (switchable between two (2) levels by using special auxiliary relays 2609 to 2612). The input time constant also has a ten (10) ms ± twenty percent (20%), ten (10) µs ± twenty (20%) for both rising (OFF to ON) and falling (ON to OFF) edges. The KV-E4XR has an inductive load voltage rating of two-hundred and fifty (250) VAC/ thirty (30) VDC, two (2) A. The KV-E4XR also has a resistive load of four (4) A.
The KV-E4XR has a rated output current of two (2) A/output (inductive load), four (4) A/output (resistive load), four (4) A/common. The KV-E4XR has no measurable current leakage while OFF and no residual voltage while turned ON. The KV-E4XR has a start-up operation time (OFF to ON and ON to OFF) often (10) ms or less. The KV-E4XR has an ON resistance of fifty (50) mΩ or less. The KV-E4XR has an electrical relay lifespan of one hundred thousand (100,000) times or more. The KV-E4XR has a mechanical relay lifespan of twenty million (20,000,000) times or more. The relay is not replaceable with this device. The KV-E4XR has a maximum input rating of twenty-six point four (26.4) VDC. The input voltage is twenty-four (24) VDC, five-point three (5.3) mA, and an input impedance of four point three (4.3) kΩ.
