General Description: The single and dual channel 24 to 220 Vac/Vdc Loop powered Switch Repeater D5093S and D5093D modules are units suitable for applications requiring SIL 3 level (according to IEC 61508:2010 Ed.2) in safety related systems for high risk industries. Each channel is able to reflect the presence of a 24 to 220 Vac/Vdc input signal to the output by closing an optically coupled NO open-drain transistor (solid-state relay, MOSFET output).

The 2 channels of the D5093D module could be used to increase the hardware fault tolerance, needed for a higher SIL of a certain Safety Function, as they are completely independent from each other, not containing common components. In fact, the analysis results got for D5093S (single channel) are also valid for each channel of D5093D (double ch.).

Connect a variable DC / AC source to any input terminals couple (7-8 for D5093S and 7-8, 9-10 for D5093D). Connect the positive output terminals (1 for D5093S and 1, 3 for D5093D) to the series of a current limiting resistor (i.e. 1 kΩ) and the positive pole of a DC voltage generator (i.e. 24 Vdc); then connect the output negative terminals (2 for D5093S and 2, 4 for D5093D) to the negative pole of the DC voltage generator.
Operation The single and dual channel 24 to 220 Vac / Vdc Loop powered Switch Repeater, D5093S and D5093D module is a unit suitable for applications requiring SIL 3 level (according to IEC 61508:2010 Ed. 2) in safety related systems for high risk industries.
