2.2 Wiring (Cont’d)
Connectors D and E are input terminals, each requiring p/n SC-CBLE25MM cable / terminal
block assembly.
Thermocouples can be connected to any input of either connector D or E.
For linear inputs (4 – 20 mA or 0 – 5 VDC) it is recommended to connect the wires to the
appropriate terminals for connector D. However, either connector D or E may be used. See
previous page for information on DIP switch settings for 4 – 20 mA inputs.
Any RTD inputs require the RTD module p/n SC-RTD, which includes the cable assembly. In
this case ,p/n SC-CBLE25MM will not be required. Note that (1) SC-RTD will handle up to 12
RTD inputs and can be connected to either connector D (Ch # 1 – 12) or connector E (Ch #
13 – 24).
Instructions for SC-RTD module configuration are in Appendix E.
