Overview Manuals Specifications Compensation Connections Installation

Features:

  • Local reference-junction compensation for two module groups
  • Dedicated screw terminals for thermocouple conductors
  • Two thermistor references carried through the cable interface
The compensation method built into IC670CHS004 measures temperature at the field-termination point instead of relying on a remote reference elsewhere in the enclosure.

Separating the thermocouple terminal block from the I/O-module base lets the temperature-sensitive field connections remain on their dedicated assembly.

IC670CHS003 provides the documented connector-to-connector arrangement when the paired thermocouple modules require a compatible two-position base.

The General Electric IC670CHS004 Thermocouple Terminal Block may remain available for quotation and legacy-system support through Apter Power.

Reference-Junction Arrangement

  • Thermistors: Two built-in thermistors provide local temperature references.
  • Module groups: Each thermistor supports the associated connected thermocouple module group.
  • Local method: The block is the preferred documented method for local cold-junction compensation.
  • Accuracy risk: Incorrect thermistor wiring can cause erroneous reported temperatures.

Thermocouple Signal Paths

  • Field terminals: Thermocouple leads connect to dedicated screw terminals.
  • Module cable: Wire-to-board connectors carry the signals to the separate I/O terminal block.
  • Polarity: Observe positive and negative thermocouple conductor assignments.
  • Pinout: Use the official connector diagram for every input and thermistor pair.

Grounding and Pairing

  • DIN rail: Mount the block on a grounded conductive DIN rail.
  • Chassis bond: Assembly screws must maintain the documented chassis-ground path.
  • Terminal base: IC670CHS003 offers the simplest connector-to-connector arrangement.
  • Inspection: Check cable seating and lead polarity before enabling local compensation.
Description
IC670CHS004 is the dedicated local reference-junction assembly for Field Control thermocouple measurements. Two built-in thermistors track terminal temperature for the two connected module groups, allowing the associated electronics to compensate the thermocouple inputs.

Thermocouple conductors land directly on the screw terminals of IC670CHS004, but the thermocouple I/O modules are mounted on a separate terminal base. Wire-to-board cables carry the input and thermistor circuits between the two assemblies.

A grounded conductive DIN rail is required so the assembly screws maintain the intended chassis-ground path. The pin assignments and thermocouple polarity shown for IC670CHS004 must be retained because a reversed lead or an incorrectly routed thermistor reference can produce an erroneous temperature.

Technical notes
IC670CHS004 keeps thermocouple leads on dedicated screw terminals while connector cables carry the measured signals and two thermistor references to the separate I/O-module base.
