D1061
- RS422 / RS485 Fieldbus Isolating Repeater
G.M. International ISM0068-12
D1061 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 D1061 associated apparatus shall be accomplished
via conduit connections or another acceptable Division 2, Zone 2 wiring method according to the NEC and the CEC.
The wiring between the Intrinsically Safe Equipment located in Hazardous Area/Hazardous Locations and the D1061 Associated Apparatus must have a minimum insulation
thickness of 0.25 mm.
Not to be connected to control equipment that uses or generates more than 250 Vrms or Vdc with respect to earth ground.
D1061 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.
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
D1061 fieldbus isolating repeater provides proper isolation and driving of an RS422/RS485 intrinsically safe line, located in Hazardous Area/Hazardous Location communicating with a
RS422/RS485 line located in Safe Area/Non Hazardous Locations.
The unit also acts as a level translator adding the capability to connect an RS232 line located in Safe Area/Non Hazardous Locations and provides the proper line commutation without
the need of additional control lines. The RS422 connection may be used on both sides instead of the RS485 2 wire connection.
Both the Profibus DP communication protocol and user-defined protocols are supported at baud rates from 1200 b/s to 1.5 MB/s for Profibus DP and from 1200 b/s up to 115200 b/s for
RS232 protocols. The unit provides the line termination capability on both Hazardous and Safe side.
The receive/transmit switching of line drivers is managed by the internal logic so that, at the end of a communication frame, the transmitting driver is held active for a time equal to
9, 10, 11 or 12 bit units before releasing the line.
A “POWER ON” green led lits when input power is present, two yellow led monitor the transmission activities.
