Sensor Connections
The OM-USB-5201 supports type types J, K, R, S, T, N, E, and B thermocouples.
Thermocouple selection
The thermocouple type you select depends on your application needs. Review the temperature ranges and
accuracies of each type to determine which is best suited for your application.
Screw terminal pin out
The OM-USB-5201 has four rows of screw terminals — two rows on the top edge of the housing, and two rows
on the bottom edge. Each row has 26 connections. Between each bank of screw terminals are two integrated
CJC sensors used for thermocouple measurements. Signals are identified in Figure 2.
