بریر ضد انفجار D5090S

توضیحات محصول

General Description
The single channel Relay Output, D5090S-086 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
Two mutually exclusive (by DIP-Switch programming) monitoring circuits are provided
1) line input monitoring, to allow DCS/PLC line monitoring function: when enabled, the
module permits a wide compatibility towards different DCS/PLC. Driving line pulse
testing, executed by DCS/PLC, is permitted by a dedicated internal circuit, to prevent
relay and LED flickering
2) low voltage input monitoring: when enabled, the module reflects a high impedance
state to the control unit when the driving voltage is below the specified threshold
D5090S-086 provides two NC contacts for normally energized load and a NO contact for
service purpose, in order to switch the NE load on both supply lines
