Figure 3-27 ADAM-4018 8-channel Thermocouple Input Module
Channels:
- Six differential, two single-ended
Accepts:
- J, K, T, E, R, S and B thermocouples
- Millivolt inputs: ±15 mV, ±50 mV, ±100 mV and ±500 mV
- Volt inputs: ±1 V and ±2.5 V
- Current input: ±20 mA (requires a 125 resistor)
The module forwards the data to the host computer in engineering units
(oC, mV, V or mA)
