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
· Fee*ack 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.
带延时的安全继电器
批准:
延时安全监控继电器:3NC 1NO输出接点和4NC 2NO延时接点
VIPER SCR-31-42TD-i带有延时和附加诊断的idm安全继电器是在英国设计和制造的，以满足好新的安全标准，并提供增强的LED诊断和简化布线。
应用包括安全联锁开关的监测(警卫门监测)，紧急停止装置和传感器。
SCR-31-42TD-i内部逻辑使用力导继电器实现交叉监控，这确保了一个单一的故障不会导致安全功能的丢失，并且所有故障都在下一个安全需求时或之前被检测到。
特点:
延时触点:4NC和2NO(0-30秒)
输出触点:3NC 1NO
监测外部接点的反馈电路-用于加强接点。
通过led的可视指示，很容易诊断状态。
至PLe, SILCL 3，类别4。
监控手动或自动启动。
单、双通道操作。
输出扩展单元可用来增加输出数量。
