1. Core Identity
IS220PTCCH1A is a Mark VIe-series thermocouple/RTD input slice that turns millivolt-level field signals into high-resolution temperature data for gas- and steam-turbine control loops.

3. Mechanical & Power
Ø Slice width: 38 mm – single-slot on Mark VIe I/O rack
Ø Power draw: 3.8 W @ 28 VDC (redundant feed from rack back-plane)
Ø Operating temp: –40 … +70 °C (G3 conformal coating standard)
4. Typical Application Hook-up
TC extension wires land on removable spring-clamp terminal blocks (IS-TBCH1A); cold-junction compensation is integrated in the slice, eliminating external ice-point references.
5. Certifications & Compliance
CE, UL 508, ATEX Zone 2, IEC 61000-6-2/4, IEEE 1613 (electric substation), RoHS.
