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).
The TCD 01 tracing control display shall be powered by an external 24 Vdc power supply. That supply can be
the same providing the 24 Vdc power to drive the solid state relays or mechanical contactors in the panel.
Two versions of the TCD 01 are available.
•
A TCD 01 for single phase current display per tracing circuit (firmware AZ 871)
•
A TCD 01 for three phase current display per tracing circuit (firmware AZ 884)
