SAFETY
EXPANSION UNIT FOR SCR-i RELAYS: 3NC and 1NO DELAYED CONTACTS (0-30
seconds)
The VIPER
SEU-31TD-i expansion unit with time delay and added diagnostics from IDEM is
designed and manufactured in the United Kingdom to meet the latest safety
standards and offer enhanced LED diagnostics and simplified wiring.
Applications
include the monitoring of safety interlock switches (guard door monitoring),
emergency stop devices and sensors.
The
SEU-31TD-i is an expansion unit with the added benefit of time delayed
contacts. It has been designed to connect to a standard VIPER SCR-i safety
relay to offer extra time delayed output contacts to the end user.
FEATURES:
· Delayed contacts: 3NC 1NO (0-30 seconds).
· Feedback circuit to monitor external contacts – used
for reinforcement of contacts.
· Easy diagnosis of status via visual indication of
LEDs.
· Up to PLd, SIL 2, Category 3.
· Monitored manual or automatic start.
· Single and dual channel operation.
· Output expansion units available to increase number
of outputs.
