D1053
- SIL 2 Analog Signal Converter and Trip Amplifiers
G.M. International ISM0016-13
D1053 is an isolated Intrinsically Safe Associated Apparatus installed into standard EN50022 T35 DIN Rail located in Safe Area/ Non Hazardous Locations or Zone 2, Group IIC,
Temperature Classification T4, Class I, Division 2, Groups A, B, C, D, Temperature Code T4 and Class I, Zone 2, Group IIC, IIB, IIA Temperature Code T4 Hazardous Area/Hazardous
Locations (according to EN/IEC60079-15, FM Class No. 3611, CSA-C22.2 No. 213-M1987, CSA-E60079-15) within the specified operating temperature limits Tamb -20 to +60 °C,
and connected to equipment with a maximum limit for AC power supply Um of 250 Vrms.
Non-incendive field wiring is not recognized by the Canadian Electrical Code, installation is permitted in the US only.
For installation of the unit in a Class I, Division 2 or Class I, Zone 2 location, the wiring between the control equipment and the D1053 associated apparatus shall be accomplished
via conduit connections or another acceptable Division 2, Zone 2 wiring method according to the NEC and the CEC.
Not to be connected to control equipment that uses or generates more than 250 Vrms or Vdc with respect to earth ground.
D1053 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), BS 5345 Pt4, VDE 165,
ANSI/ISA RP12.06.01 Installation of Intrinsically Safe System for Hazardous (Classified) Locations, National Electrical Code NEC ANSI/NFPA 70 Section 504 and 505,
Canadian Electrical Code CEC) following the established installation rules, particular care shall be given to segregation and clear identification of I.S. conductors from non I.S. ones.
De-energize power source (turn off power supply voltage) before plug or unplug the terminal blocks when installed in Hazardous Area/Hazardous Locations or
unless area is known to be nonhazardous.
Warning: substitution of components may impair Intrinsic Safety and suitability for Division 2, 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.
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.
Warning
Operation
Input channel of D1053 accepts a current or voltage signal from Hazardous Area/Hazardous Locations from separately powered 3, 4 wire transmitter, voltage or current source, and
repeats or converts the current or voltage to a 0/4-20 mA or 0/1-5 V or 0/2-10 V floating output to drive a load in Safe Area/Non Hazardous Locations. In addition to the analog output the
barrier has also a two channel trip amplifiers providing two relay SPST contacts, alarm A and B, that can be configured as HIGH, LOW, LOW start-up, BURNOUT alarm operating mode
and NE or ND relay operating mode. Presence of supply power is displayed by a green signaling LED, status of alarm output A and B is displayed by two red LED.
