The dual channel Switch/Proximity Detector Repeater, D5030D, module is a unit suitable for applications requiring SIL 3 level (according to IEC 61508) in safety related systems for high risk industries.

The unit can be configured for switch or proximity detector (EN60947-5-6, NAMUR), NO or NC and for NE or ND SPST (D5030D) or SPDT (D5030S) relay output contact. Each channel enables a Safe Area load to be controlled by a switch, or a proximity detector, located in Hazardous Area.

Fault detection circuit (DIP switch configurable) is available for both proximity sensor and switch equipped with end of line resistors. In case of fault, when enabled it de-energizes the corresponding output relay and turns the fault LED on; when disabled the corresponding output relay repeats the input line open or closed status as configured.

D5030D is programmable via dip switches as single input and two independent outputs. Out 2 can be programmed for output duplicating Out 1 or Fault detection Out. In case of duplication, relay actuation can be independently configured for each output. In case of fault output, relay actuation can be programmed as normally energized or normally de-energized. Mounting on standard DIN-Rail, with or without Power Bus, in Safe Area or in Zone 2.

SIL Level:
D5030D, according IEC 61508 & IEC 61511, is suitable for applications up to safety integrity level SIL 3.
SIL 3 according to IEC 61508 for Tproof = 2 / 4 years (10 / 20 % of total SIF), considering 100 mA max contact current.
SIL 2 according to IEC 61508 for Tproof = 5 / 10 years (10 / 20 % of total SIF), considering 4 A max contact current.
