D5048S SIL 3 Digital Output Driver, NE Loads, Loop Powered, DIN-Rail and Termination Board INSTRUCTION MANUAL
■The single channel Loop Powered Digital Output Isolator, D5048S, is suitable for driving solenoid valves, visual or audible alarms to alert a plant operator, or other process control devices in Hazardous Area from a driving signal in Safe Area. It can also be used as a controllable supply to power measuring or process control equipment.
■Its use is allowed in applications requiring up to SIL 3 level (according to IEC 61508:2010 Ed. 2) in safety related systems for high risk industries.
■The Safety PLC or DCS driving signal powers the field device through the D5048S, which provides isolation and is capable of monitoring the conditions of the line.
■Short and open circuit diagnostic monitoring, dip-switch selectable and active when input power is present, provides LED indication and NC transistor output signaling.
■When fault is detected output is de-energized until normal condition is restored. Line short and open output circuit fault detection is also reflected on the PLC / DCS input circuit providing less than 10 mA consumption. In alternative, input impedance can be set to a value always lower than 2 kΩ.
■An override input, dip-switch selectable, is provided to permit a safety system to override the control signal. When enabled, a low input voltage always de-energizes the field device regardless of the input signal.
■Three basic output circuits are selectable, with different safety parameters, to interface the majority of devices on the market.
■The selection among the three output characteristics is obtained by connecting the field device to a different terminal block.
■Mounting on standard DIN-Rail, with or without Power Bus to provide fault signal, or on customized Termination Boards, in Safe Area / Non Hazardous Location or in Zone 2 / Class I, Division 2 or Class I, Zone 2.
