GL100 Terminal
4ch Voltage / Temperature Terminal

Voltage Temp Logic Pulse Terminal

Connects the GL100 for up to 4ch of voltage DC (20mV to 50V as well as 1-5V) and thermocouple (K or T type) temperature measurement. Each voltage / temperature channel is configurable. Combination of pulse and logic channels can be measured at the same time.
