EQUIPMENT:
Equipment and systems covered by this Certificate are as follows:
The Relay Barriers of types EB3C-*N, EB3L-*N, EB3N-* and EB3S-B*N are associated apparatus intended for connection to passive
intrinsically safe circuits. They are provided with intrinsically safe I/O-circuits which can differ in the number of channels from 1 channel up to a
maximum of 16 channels. The signals of the intrinsically safe circuits are electrically isolated from the non-intrinsically safe circuits byoptocouplers and they are available via relay contacts or transistor switches.
Ambient Temperature -20 °C to +60 °C.
For electrical data, see the Annex to NL/DEK/ExTR21.0081/00.
Installation instructions
The instructions provided with the product shall be followed in detail to assure safe operation.
To maintain intrinsic safety, the signal input or output terminals (secondary) may only be connected to intrinsically safe circuits where both thewiring and the connected equipment maintain 500 V isolation to the hazardous area earthing/bonding connections, per clause 6.3.13 of IEC
60079-11 : 2011.
