Warning
Operation
D5090S relay module is suitable for the switching of safety related circuits, providing isolation between the input and output contacts.
D5090S provides two NO contacts for normally energized load and a NC contact for service purpose, in order to switch the NE load on both supply lines.
A “RELAY STATUS” yellow led lights when input is powered, showing that relay is energized.
Installation
D5090-102 series are relay output module housed in a plastic enclosure suitable for installation on EN/IEC60715 TH 35 DIN-Rail or on customized Termination Board.
D5090-102 series can be mounted with any orientation over the entire ambient temperature range.
Electrical connections are accommodated by polarized plug-in removable screw terminal blocks which can be plugged in/out into a powered unit without suffering or causing any damage
(for Zone 2 installations check the area to be nonhazardous before servicing).
Connect only one individual conductor per each clamping point, use conductors up to 2.5 mm²
(13 AWG) and a torque value of 0.5
-
0.6 Nm. Use only cables that are suitable for a temperature of at least 85°C.The wiring cables have to be proportionate in base to the current and the
length of the cable.
On the section “Function Diagram” and enclosure side a block diagram identifies all connections.
Identify the function and location of each connection terminal using the wiring diagram on the corresponding section, as an example:
Connect positive input at terminal “1” and negative input at “2”.
Connect positive Load Power DC/AC at terminal “7” and negative at terminal “8”.
Connect positive output NE or F&G/ND load at terminal “11” and negative at terminal “12”.
Installation and wiring must be in accordance to the relevant national/international installation standards (e.g. EN/IEC60079
-
14 Electrical apparatus for explosive gas atmospheres

Part
14: Electrical installations in hazardous areas (other than mines)), make sure that conductors are well isolated from each other and do not produce any unintentional connection.
Connect load relay contacts checking the load rating to be within the contact maximum rating (5 A 250 Vac 1250 VA, 5 A 250 Vdc 140 W resistive load).
To prevent relay contacts from damaging, connect an external protection (fuse or similar), chosen according to the relay breaking capacity diagram from installation
instructions.
The enclosure provides, according to EN60529, an IP20 minimum degree of protection (or similar to NEMA Standard 250 type 1). The unit shall be installed in an area of no more than
pollution degree 2 according to EN/IEC60664
-
1. When installed in EU Zone 2, the unit shall be mounted in a certified Ex enclosure that provides a degree of protection not less than IP54
in accordance with EN/IEC60079-15. When installed in a Class I, Division 2 Hazardous Location, the unit shall be mounted in a supplemental enclosure that provides a degree of
protection not less than IP54. The enclosure must have a door or cover accessible only by the use of a tool. The end user is responsible to ensure that the operating temperature of the
module is not exceeded in the end use application.
Units must be protected against dirt, dust, extreme mechanical (e.g. vibration, impact and shock) and thermal stress, and casual contacts. If enclosure needs to be cleaned use only a
cloth lightly moistened by a mixture of detergent in water.
Electrostatic Hazard: to avoid electrostatic hazard, the enclosure of D5090-102 series must be cleaned only with a damp or antistatic cloth.
Any penetration of cleaning liquid must be avoided to prevent damage to the unit.
Any unauthorized card modification must be avoided.
All circuits connected to D5090-102 series must comply with the overvoltage category II (or better) according to EN/IEC60664
-
1.
Warning: de-energize main power source (turn off power supply voltage) and disconnect plug-in terminal blocks before opening the enclosure to avoid electrical shock
when connected to live hazardous potential.
D5090-102 series are electrical apparatus installed on EN/IEC60715 TH 35 standard DIN-Rail located in Safe Area/Non Hazardous Locations or Zone 2, Group IIC T4 or Class I, Division
2, Group A, B, C, D, T4 Hazardous Area within the specified operating temperature limits Tamb - 40 to +70 °C.
D5090-102 series must be installed, operated and maintained only by qualified personnel, in accordance to the relevant national/international installation standards (e.g. IEC/EN60079-
14 Electrical apparatus for explosive gas atmospheres - Part 14: Electrical installations in hazardous areas (other than mines)), following the established installation rules. De-energize
power source (turn off power supply voltage) before plug or unplug the terminal blocks when installed in Hazardous Area or unless area is known to be nonhazardous.
Warning: substitution of components may impair suitability for Zone 2/Division 2. Avertissement: la substitution des composants peut nuire à l’aptitude à la Zone 2/Div. 2.
Explosion Hazard: to prevent ignition of flammable atmospheres, disconnect power before servicing or unless area is known to be nonhazardous. Danger d'Explosion: pour
éviter l’inflammation d’atmosphères inflammables, débrancher l’alimentation avant l’entretien ou à moins que région est connue pour être non dangereuse.
Warning: de
-
energize main power source (turn off power supply voltage) and disconnect plug
-
in terminal blocks before opening the enclosure to avoid electrical shock
when connected to live hazardous potential. Avertissement: débrancher l’alimentation (couper la tension d'alimentation) et les blocs de jonction enfichables avant d’ouvrir
le boîtier pour éviter les chocs électriques lorsqu’ils sont connectés à un potentiel dangereux.
Failure to properly installation or use of the equipment may risk to damage the unit or severe personal injury.
The unit cannot be repaired by the end user and must be returned to the manufacturer or his authorized representative. Any unauthorized modification must be avoided.
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 energized because relay output contacts (Out 1 and Out 2) are closed.
Indeed, disabling input, the “RELAY STATUS” yellow led must be turned off and load circuit must be de-energized because relay output contacts (Out 1 and Out 2) are open.
