SAFETY
MONITORING RELAY. 2NC and 1NO CONTACTS.

The VIPER
SCR-21-i safety monitoring relay with added diagnostics from IDEM had been
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-21-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.

FEATURES:

·       Outputs 2NC contacts and 1NO contact.

·       Feedback circuit to monitor external contacts.

·       Easy diagnosis of status via visual indication of
LEDs.

·       Up to PLe, SILCL 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-21-i安全繼電器

批準:

安全監測繼電器。

2NC和1NO觸點。

VIPER
SCR-21-i安全監測繼電器是在英國設計和制造的，附加了IDEM的診斷，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。

SCR-21-i內部邏輯采用力導繼電器實現交叉監控，確保單個故障不會導致安全功能的丟失，并確保所有故障在下一次安全需求時或之前被檢測到。

特點:

輸出2NC觸點和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。

至PLe, SILCL 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。
