SAFETY
MONITORING RELAY WITH TIME DELAY: 3NC 1NO OUTPUT CONTACTS and 4NC  2NO
DELAYED CONTACTS

The VIPER
SCR-31-42TD-i safety relay with time delay with added diagnostics from IDEM has
been designed and manufactured in the UK 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-31-42TD-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:

·       DELAYED contacts: 4NC and 2NO (0-30 secs)

·       OUTPUT contacts: 3NC 1NO

·       Feedback circuit to monitor external contacts – used
for reinforcement of 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.

帶延時的安全繼電器

延時安全監(jiān)控繼電器:3NC 1NO輸出接點和4NC 2NO延時接點

VIPER
SCR-31-42TD-i帶有延時和附加診斷的idm安全繼電器是在英國設(shè)計和制造的，以滿足新的安全標(biāo)準(zhǔn)，并提供增強(qiáng)的LED診斷和簡化布線。

應(yīng)用包括安全聯(lián)鎖開關(guān)的監(jiān)測(警衛(wèi)門監(jiān)測)，緊急停止裝置和傳感器。

SCR-31-42TD-i內(nèi)部邏輯使用力導(dǎo)繼電器實現(xiàn)交叉監(jiān)控，這確保了一個單一的故障不會導(dǎo)致安全功能的丟失，并且所有故障都在下一個安全需求時或之前被檢測到。

特點:

延時觸點:4NC和2NO(0-30秒)

輸出觸點:3NC 1NO

監(jiān)測外部接點的反饋電路-用于加強(qiáng)接點。

通過led的可視指示，很容易診斷狀態(tài)。

至PLe, SILCL 3，類別4。

監(jiān)控手動或自動啟動。

單、雙通道操作。

輸出擴(kuò)展單元可用來增加輸出數(shù)量。
