Repair GE-Emerson IC670CHS101 Field Control Hot Insertion I/O Terminal Block

The GE-Emerson IC670CHS101 Field Control Hot Insertion I/O Terminal Block is a generic wiring base that provides module mounting, backplane communications, and terminals for user connections. Two modules can be installed on one germinal block. Modules screw into the terminal block for vibration resistance. Modules can be removed without disturbing field wiring.

The I/O Terminal Block includes 37 terminals. The A and B terminals are typically used for power connections to the terminal block. The rest of the terminals are individually used for I/O wiring.

Each terminal on an I/O Terminal Block or Auxiliary Terminal Block with Barrier Terminals accommodates up to two AWG #14 through AWG #22 wires. Use copper wire rated for 194°F. Recommended terminal torque is 8in/lb. 

The safety ground wire should be AWG #14, not more than 4in long.

The Hot Insertion Terminal Block permits hot insertion/removal of modules without affecting the Bus Interface Unit or other modules in the I/O station. Hot insertion/removal can only be performed in non-hazardous locations.
