D1093
D1093 SIL 3 Relay Output Module with
Line and Load diagnostics DIN-Rail
Model D1093S
General Description:
The single channel DIN Rail Relay Output D1093S is a relay module suitable for the
switching of safety related circuits, up to SIL 3 level according to IEC61508, for high risk
industries. It provides isolation between the input and output contact.
D1093S provides 1 DPST contact for normally energized loads and
1 SPST contact for normally de-energized loads.
Diagnostic:
Line breakage detection for NE and ND load conditions.
Provides 1 SPST normally energized relay contact (closed) for fault indication.
It de-energizes (open contact) in case of load or line fault.
Function:
1 relay for safety related circuits, provides isolation between input/output/fault.
D1093S provides 1 DPST for NE loads and 1 SPST for ND loads.
SIL 3 Safety Function for NE load (de-energized in safe state) is available at
Terminal Blocks 5-6;
in this case, the safety function is met when the relay is de-energized (open contact).
SIL 3 Safety Function for ND load (energized in safe state) is available at
Terminal Blocks 7-8;
in this case, the safety function is met when the relay is energized (closed contact).
Signalling LEDs:
Power supply indication (green), relay status (yellow), line fault (red).
EMC:
Fully compliant with CE marking applicable requirements.
