- Page 5 Safety Function and Failure behavior: D5090S-086 is considered to be operating in Low Demand mode, as a Type A module, having Hardware Fault Tolerance (HFT) = 0. In the 1st Functional Safety application, the normal state operation of relay module is de-energized, with NE (Normally Energized) load.
- Page 6 Safety Function and Failure behavior: D5090S-086 is considered to be operating in Low Demand mode, as a Type A module, having Hardware Fault Tolerance (HFT) = 0. In the 2nd Functional Safety application, the normal state operation of relay module is de-energized, with NE (Normally Energized) load.
- Page 7 D5090S-086 relay module is suitable for the switching of safety related circuits, providing isolation between the input and output contacts. D5090S-086 provides two NC contacts for normally energized load and a NO contact for service purpose, in order to switch the NE load on both supply lines.
- Page 8 Start-up Before powering the inputs of unit check that all wires are properly connected, also verifying their polarity. Check conductors for exposed wires that could touch each other causing dangerous unwanted shorts. Enabling input, the “RELAY STATUS” yellow led must be lit and load circuit must be de-energized because relay output contacts (Out 1 and Out 2) are open. Indeed, disabling input, the “RELAY STATUS”...
