SAFETY
MONITORING RELAY: 3NC and 1NO CONTACTS.
The VIPER
SCR-31-i safety monitoring relay with 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
SCR-31-i internal logic uses force guided relays to achieve cross monitoring,
this ensures that a single fault does not lead to the loss of the safety
function and that all faults are detected at or before the next safety demand.
*Note: For
items using PNP inputs such as safety light curtains and safety mats please
choose SCR-31P-i model.
FEATURES:
· Outputs 3NC contacts and 1NO contact.
· Feedback circuit to monitor external contacts.
· Easy diagnosis of status via visual indication of
LEDs.
· Up to PLe, SIL 3, Category 4.
· Monitored manual or automatic start.
· Single and dual channel operation.
· Output expansion units available to increase number
of outputs.
附加診斷的VIPER SCR-31-i安全繼電器
批準:
安全監控繼電器:3NC和1NO觸點。
VIPER
SCR-31-i安全監測繼電器是由IDEM公司在英國設計和制造的，以滿足新的安全標準，并提供增強的LED診斷和簡化布線。
應用包括安全聯鎖開關的監測(警衛門監測)，緊急停止裝置和傳感器。
scl
-31-i內部邏輯使用力導繼電器實現交叉監控，這確保了一個單一的故障不會導致安全功能的丟失，并且所有的故障都在下一個安全需求時或之前被檢測到。
*注:如使用PNP輸入，如安全燈罩、安全墊，請選擇scl - 31p -i型號。
特點:
輸出3NC和1NO觸點。
反饋電路監控外部接點。
通過led的可視指示，很容易診斷狀態。
到PLe, SIL 3，類別4。
監控手動或自動啟動。
單、雙通道操作。
輸出擴展單元可用來增加輸出數量。
