Three types of input system enable to measure various phenomena

Input system 1 : Multifunction analog input ports

Contains a highly isolated input system which ensures that signals are not corrupted by noise from other channels. The GL840's inputs are suitable for combined measurements
from voltage, temperature, humidity, logic, and pulse signals.

The standard configuration has 20 analog input channels. It is expandable to 200 channels by adding optional 20 channels extension terminal base unit (B-566) and input
terminal units (B-564 or B-565).

Withstand voltage & Accuracy		Multi-input type (B-564)	Withstand-voltage type (B-565)
Voltage	Input voltage range	20 mV to 100 V	20 mV to 100 V
Voltage	Max. voltage (Input - GND)	60 Vp-p	300 Vp-p
Temp.	Thermocouple	R, S, B, K, E, T, J, N, W (WRe5-26)
Temp.	RTD (Resistance Temp. Detector)	Pt100 (IEC751), Pt1000 (IEC751), JPt100 (JIS)
Accuracy	Voltage	± 0.1% of F.S.	± (0.05% of FS + 10μV)
Accuracy	Temperature*	± 1.55 ºC	± 1.1 ºC

* Accuracy rating for K-type thermocouple at 100˚C includes reference junction compensation. Accuracy varies by temperature levels and thermocouple types.

The following shows how a standard configuration is expanded to more than 40 channels
