Bulletins 900-TC8 and 900-TC16
Note: Input power supply available: 100…240 V AC, or 24 V AC/DC
Bulletin 900-TC8 — Wiring Terminals
Option Unit Terminals, refer to page 9-211.
 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.
 Solderless lugs are recommended when wiring to the Bulletin 900-TC8/900-TC16 wire terminals. However, if lugs are not used, the
controller’s screw terminals will accept two solid or stranded wires (no mixing) 14…24 AWG.
 Tighten the terminal screws using a torque 0.74…0.90 N•m.
 Use a 7.2 mm open or round solderless lug for M3.5 screws.
 Never attempt to remove the controller terminal block from the controller case. Damage may result.
