9202A
Pulse isolator
9202A
– Interface for NAMUR sensors and switches
– Extended self-diagnostics and detection of cable fault
– 1 or 2 channels
– Can be supplied separately or installed on power rail, PR type 9400
– SIL 2-certified via Full Assessment
Advanced features
• Configuration and monitoring by way of detachable display
front (PR 4511/4501).
• Selection of direct or inverted function for each channel via
PR 4511/4501.
• Advanced monitoring of internal communication and stored
data.
• Optional redundant supply via power rail and/ or separate
supply.
• SIL 2 functionality is optional and must be activated in a menu
point.
Connections
Application
• The device can be mounted in and receive signals from nonclassified area and zone 2.
• Pulse isolator for transmission of signals from NAMUR
sensors and mechanical switches.
• Monitoring of error events and cable breakage via the
individual status relay and/or a collective electronic signal via
the power rail.
• The 9202A has been designed, developed and certified for
use in SIL 2 applications according to the requirements of IEC
61508.
Technical characteristics
• 1 green and 2 yellow/red front LEDs indicate operation status
and malfunction.
• 2.6 kVAC galvanic isolation between input, output and supply.
Mounting
• The devices can be mounted vertically or horizontally without
distance between neighbouring units.
