  • Page 4: Introduction

    This concept allows total electrical heat tracing control configured to the needs of the customer. The TC 816 hardware is based on electronic modules. With this approach the TC 816 can be set up for a huge variety of control tasks required for all electric heat tracing concepts Thermon has to offer.

  • Page 5: The Tc 816 For Process Temperature Maintenance

    TC 816 Operation Manual The TC 816 for Process Temperature Maintenance The enclosure of the TC 816 is constructed to be mounted on the back plane of a panel. The enclosure facili- tates 6 slots for electronic modules, each having its particular task.

  • Page 6: Slot 3: For Af Tit Tracing Input Module For Temperature

    The advantage is, that off the shelf Solid State relays can be connected to the TC 816 so switching capacity of a TC 816 system is only limited by the panel construction parameters like feeding power, cooling capacity in the panel.

  • Page 7: The Tcd 01 Tracing Control Display

    The TCD 01 tracing control display allows the operator to have full control over the heat tracing circuits which are controlled by the connected TC 816 temperature controllers. The TCD 01 is the host on the RS 485 data communication bus. It searches on the communication bus for TC 816 heat tracing temperature controllers which need to have their own unique communication address (to be set by DIP switches on the AF TC4 tracing central processing module).
