KV-E4R is a four (4) relay output by Keyence. The KV-E4R has a rated load voltage of two-hundred and fifty (250) VAC/ Thirty (30) VDC, with a two (2) A inductive load and a resistive load of four (4) A.
The rated output current of the KV-E4R is a two (2) A/output (inductive load) with a four (4) A/output (resistive load) and a four (4) A/common.
The KV-E4R has no measurable current leakage while OFF. The KV-E4R has no measurable voltage residual while turned ON. The KV-E4R has a startup operation time (OFF to ON) and (ON to OFF) of ten (10) ms or less. The KV-E4R has an ON resistance of fifty (50) mΩ or less. The KV-E4R has an electrical relay lifespan of a hundred thousand (100,000) times or more (twenty (20) times/minute). The KV-E4R has a mechanical relay lifespan of twenty million (20,000,000) times or more. Relay replacement for the KV-E4R is not possible. The KV-E4R weighs approximately one hundred (100) grams. The Keyence KV-E4R is made of black plastic with a black and white wiring harness on the left. The KV-E4R has two (2) white buttons on the left labeled "CH". The top of the device is labeled in purple C1 zero through three (C1 0-3) with an OUT port on the top right. Along the bottom of the device is labeled in purple V1, V2, V3, V4, V5, with an OUT port on the bottom right. There are also four (4) LED lights labeled zero through three (0-3) and the fourth is labeled Ready/Error.
