General Description: The The D5294S is a relay module suitable for the switching of safety related circuits, up to SIL 3 level according to IEC 61508:2010 Ed. 2 for high risk industries.
It provides isolation between input and output contacts. A wide compatibility towards different DCS/PLC is guaranteed: driving line pulse testing, executed by DCS/PLC, is permitted by
a dedicated internal circuit, to prevent relay and LED flickering. Internal relay coil short circuit is detected by the module. D5294S has 2+2 SPST relay contacts connected in parallel
and then in series to avoid spurious trips and to increase availability (see function diagram). High availability SIL 3 Safety Function for NE load or F&G / ND load is available at Terminal
Blocks 13-14. When the driving signal is low (0 Vdc), the relay is de-energized, contacts at terminals 13-15 and 14-16 are open and load is de-energized. When the driving signal is
high (24 Vdc), the relay is energized, contacts at terminals 13-15 and 14-16 are closed, the load is energized. Load is isolated from supply on both polarities: +/AC, -/AC.
Load and Line Diagnostic: Line and load short/open circuit detection is provided, with solenoid resistance measurement, even in presence of series connected diodes.
A patented proprietary resistance measuring technique performs the load short and open circuit diagnosis in de-energized load status, for DC or AC supply systems. Load RMS voltage
(before and after its energization) and current are measured by the module. Load voltage, current and resistance can automatically be acquired from field. User configurable limits set
the minimum and maximum values of load resistance, supply voltage (DC or AC) and load current. Earth leakage detection on both AC phases is available in de-energized load condi-
tion. The fault in the field is directly mirrored to the PLC DO: few systems may exceptionally require an external resistor at terminals 7 and 8. All diagnostic conditions, that detect a fault
on line and load, open the fault relay contacts and are also available from a RS485 Modbus output to identify any specific fault. Diagnostic functions with fault relay NO contacts and
RS485 Modbus output are SIL 2 rated according to IEC 61511. Mounting on standard DIN-Rail, with or without Power Bus, or on customized Termination Boards, in Safe Area / Non
Hazardous Location or in Zone 2 / Class I, Division 2 or Class I, Zone 2.
Functional Safety Management Certification:
G.M. International is certified by TUV to conform to IEC61508:2010
part 1 clauses 5-6 for safety related systems up to and included SIL3.
The module is fully programmable to set the operation parameters from PC by the GM Pocket Portable Adapter PPC5092 via USB serial line and SWC5090 Configurator software.
Measured values and diagnostic alarms can be read on both serial configuration or Modbus output line.
