D5098
- 5 A SIL 3 Relay Out Module for NE Load
G.M. International ISM0305-2
Warning
Operation
The single and dual channel D5098S and D5098D Relay Output modules are suitable for the switching of safety related circuits, up to SIL 3 level according to IEC 61508:2010 Ed.2,
for high risk industries. They provide isolation between input and output contacts. D5098S provides one NO contact for normally energized loads and one NC contact for service
purposes. D5098D provides two NO contacts for two normally energized loads and two NC contact for service purposes. When driving signals (terminals 1-2 for Channel 1 and 3-4 for
Channel 2, only for D5098D) are low (0 Vdc), the relays are de-energized, contacts at terminals 7-8 (for Channel 1) and 9-10 (for Channel 2) are open and loads are de-energized. When
driving signals are high (24 Vdc), the relays are energized, contacts at terminals 7-8 and 9-10 are closed and loads are energized. For each channel, presence of status of input / output
channel (energized or de-energized) is displayed by yellow LED.
Installation
D5098S and D5098D are relay output modules housed in a plastic enclosure suitable for installation on T35 DIN-Rail according to EN50022, or on customized Termination Board.
D5098 unit can be mounted with any orientation over the entire ambient temperature range. Electrical connection of conductors up to 2.5 mm² 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).
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” for Channel 1.
Connect positive input at terminal “3” and negative input at “4” for Channel 2 (only for D5098D).
For channel 1 output, connect positive or AC load supply line to contact common pole at terminal “7”.
Always for channel 1 output, connect SIL 3 NE load between negative or AC load supply line and the contact pole at terminal “8”.
In addition, if it’s necessary, connect service load (Not SIL) between negative or AC load supply line and the contact pole at terminal “11”.
For channel 2 output, connect positive or AC load supply line to contact common pole at terminal “9”.
Always for channel 1 output, connect SIL 3 NE load between negative or AC load supply line and the contact pole at terminal “10”.
In addition, if it’s necessary, connect service load (Not SIL) between negative or AC load supply line and the contact pole at terminal “12”.
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.
For each contact, 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 on data sheet.
The enclosure provides, according to
EN60529, an IP20 minimum degree of protection (or similar to NEMA Standard 250 type 1). For non-hazardous location, the unit shall be installed in an area of not more than pollution
degree 2. For hazardous location, the unit shall be installed in a certified Ex enclosure with a minimum ingress protection of at least IP54 in accordance with EN/IEC60079-15. 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 D5098 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. According to EN61010, D5098 must be connect-
ed to SELV or SELV-E power supplies. Relay output contact must be connected to load non exceeding category II overvoltage limits.
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.
D5098S and D5098D are electrical apparatus installed into standard EN50022 T35 DIN-Rail located in Safe Area or Zone 2, Group IIC, Temperature Classification T4, Hazardous Area
(according to EN/IEC60079-15) within the specified operating temperature limits Tamb - 40 to +70 °C. D5098 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. 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
.
Explosion Hazard: to prevent ignition of flammable or combustible atmospheres, disconnect power before servicing or unless area is known to be
nonhazardous.
Provision shall be assured, external to the equipment by the installation location, to provide a transient protection to not exceeding 120V or 140% of the peak rated voltage (whichever is
the greater) at the power supply terminals. 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 unit check that all wires are properly connected, particularly supply conductors and their polarity, input and output wires. Check conductors for exposed wires that
could touch each other causing dangerous unwanted shorts. Enabling each input, the related channel status yellow led must be lit and related load circuit must be energized because
relay output contacts are closed. Instead, disabling each input, the related channel status yellow led must be turned off and related load circuit must be de-energized because relay
output contacts are open.
