external 5mm (0.2in) jumper such as Altech #8879 can be used to connect adjacent points. When

an external jumper is used, the wire capacity is reduced from AWG #14 (2.10mm

2Wire to Board Connectors

The I/O Terminal Block with Connectors (catalog number IC670CHS003 and 103) has two 20-pin

male connectors for I/O wiring. The mating connector is Amp part number 178289-8. The

connectors are keyed to prevent wrong insertion. Any tin-plated contact in the AMP D-3000 series

can be used with the connector (Amp part number 1-175217-5 for high contact force receptacle for

20-24 gauge (0.20-0.56mm

2wires), 1-175218-5 for high contact force receptacle for 16-20 gauge

(0.56-1.42mm

). A kit containing two mating connector housings and contacts is available as GE

Fanuc part number IC670ACC003. The kit contains pins for 16-20 gauge wire. A crimping tool is

not provided in this kit.

Thermocouple Terminal Block

The Thermocouple Terminal Block (IC670CHS004), which has two built-in thermistors, can be

used to provide local reference junction compensation for thermocouples used in conjunction with

Field Control Thermocouple modules.

Thermocouples are connected to the screw terminals on the Thermocouple Terminal Block.

Thermocouple modules are installed on a separate I/O Terminal Block (IC670CHS003, -002, or

-001) and connected to Wire-to-Board connectors on the Thermocouple Terminal Block. Terminal

Block IC670CHS003 provides connector to connector installation
