8521-TC-SA Safety Control Module

8521-TC-SA can be placed directly after the Profibus DP master to convert a single-cable bus into a redundant bus; it can also be placed in the slave to convert a redundant bus into a non-redundant cable, and at the same time, it has the performance of optocoupler isolation and interference reduction. The product is industrial grade design, IP30 protection level, wave pattern aluminium reinforced chassis, 35mm rail mounting, DC (9-36) V wide power input, with relay alarm output, dual power supply redundancy and isolation protection and other advantages.

8521-TC-SA Features:

* Support the predetermined communication rate in the standard specification.

* Supports dip switches to manually set all the standard rates or rate adaptive (all electrical interfaces must be the same rate).

* 6 dual-colour LED status indicators, power failure relay output alarm.

* 4000V lightning protection, 1.5 A overcurrent, 600W surge protection for electrical interface. Industrial grade design, EMC test certification.

* DC9-36V wide redundant dual power supply, DC1500V power isolation, reverse connection protection.

* IP30 protection level, wave pattern aluminium reinforced chassis, using standard industrial 35mm rail mounting.
