Wiring Terminals — General Guidelines
Bulletin 900-TC16 Option Unit Terminals, refer to Option Unit Wiring
Bulletin 900-TC32 — Wiring Terminals
Note: Input power supply available: 100…240 V AC, or 24 V AC/DC
Bulletin 900-TC32
 The voltage output (SSR control output) is not electrically isolated from the controller’s internal circuits. When using a grounded
thermocouple, do not connect the control output terminals to earth ground. If the control output terminals are connected to earth ground,
errors will occur in the measured temperature values as a result of ground loop leakage current.
 Standard insulation ratings exist between any of the following: power supply terminals, input terminals, output terminals, and
communication terminals. If reinforced insulation is required, provide additional insulation, such as spacial distance or material insulation,
as defined by IEC 60664.
 Separate input leads and power lines to protect the Bulletin 900-TC8/900-TC16 and its lines from external noise.

RS-485 Communications Unit (Series B) ‡§
1 With 900Builder Lite Software
 900-CP1x or equivalent cable provides the physical connection between the PC and controller.
‡ Typically, an RS-232 to RS-485 converter such as the Cat. No. 900-CONVZ25 (see page 9-213) will be required between the personal computer (with
900Builder Lite softwar
e) and the Bulletin 900-TCx controller. In that case, a 900-CPx or equivalent cable provides the physical connection between the
converter and the PC. RS-485 allows linking up to 31 controllers with a single personal computer.
§ Series B provides baud rates up to 57.6 K bps.
