Warning
Operation
The single and dual channel 24 to 220 Vac / Vdc Loop powered Switch Repeater, D5093S-TB and D5093D-TB 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.
Each channel is able to reflect the presence of a 24 to 220 Vac / Vdc input signal to the output by closing an optocoupled NO open-drain transistor.
The presence of the input signal is also indicated by a “STATUS CHANNEL” Yellow LED on the front panel.
Installation
D5093-TB series are 24 to 220 Vac / Vdc Loop powered Switch Repeater modules housed in a plastic enclosure suitable for installation on customized Termination Board.
D5093-TB series can be mounted with any orientation over the entire ambient temperature range.
Electrical connection 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. For USA and Canada installations, 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.
In case of installation in zone 2, the connecting cables of non-intrinsically safe circuits must be safely routed in a cable duct or similar. The distance between the pluggable connection
terminal and the cable duct should not exceed 500 mm cable length.
On the section “Function Diagram” and enclosure side a block diagram identifies all connections.
Installation and wiring must be in accordance to the relevant national or international installation standards (e.g. IEC/EN60079-14 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 output transistors checking the load rating to be within the maximum rating (50 mA at 35 Vdc (
≤
0.5 Vdc voltage drop)).
The enclosure provides, according to EN60529, an IP20 minimum degree of protection (or similar to NEMA Standard 250 type 1). The equipment shall only be used in an area of at least
pollution degree 2, as defined in IEC 60664-1. When installed in EU Zone 2, the unit shall be installed in an enclosure that provides a minimum ingress protection of IP54 in accordance
with IEC 60079-0. 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 D5093-TB 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 D5093-TB 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.
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. When loop powered signal is applied to input channel with a value more than 21 Vac / Vdc for threshold 1, 40 Vac / Vdc for threshold 2, 50 Vac / Vdc for
threshold 3, 100 Vac / Vdc for threshold 4, 200 Vac / Vdc for threshold 5, the corresponding transistor output must be closed and the “STATUS CHANNEL” yellow LED must be lit.
Instead, when loop powered signal is less than 15 Vac / Vdc for threshold 1, 30 Vac / Vdc for threshold 2, 35 Vac / Vdc for threshold 3, 75 Vac / Vdc for threshold 4, 160 Vac / Vdc for
threshold 5, the corresponding transistor output must be open and the “STATUS CHANNEL” yellow LED must be turned off.
D5093-TB series is electrical apparatus installed on customized Termination Board located in Safe Area or Zone 2, Group IIC, Temperature Classification 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.
D5093-TB 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.
