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.
