Voltage & Temperature Input Terminal (GS-4VT) input module

Item		Description
Type of measurement		Analog voltage or Temperature, Logic (signal pattern) or Pulse (instant or accumulated count)
Number of channel		Voltage/Temperature: 4 channels (measurement type for channels can each be separately selected) Logic/pulse: 4 channels (measurement type for channels can be selected as set of 4 channels)
Input method of voltage/temp.		Scans by the photo-MOS-relay, all channels isolated input
Measuring range of voltage		20, 50, 100, 200, 500 mV, 1, 2, 5, 10, 20, 50 V F.S. and 1-5V F.S.
Measuring accuracy		0.15 % of F.S.
Input impedance		1 M ohms
Maximum input voltage		Between positive ("+") and negative ("-") input terminal: 60 V Between negative ("-") terminal of channels: 60 V Between negative ("-") terminal of channel and "GND": 60 V
Withstand voltage		Between negative ("-") terminal of channels: 350 V p-p (1 minute) Between negative ("-") terminal of channel and "GND": 350 V p-p (1 minute)
Measuring range of temperature		Thermocouple: K type -200 °C to 1370 °C, T type -200 °C to 400 °C
Measuring accuracy		K type -200 ≤ TS ≤ -100 °C: ± (0.05% of reading + 2.0 °C) -100 < TS ≤ 1370 °C: ± (0.05% of reading + 1.0 °C) T type -200 ≤ TS ≤ -100 °C: ± (0.1% of reading + 1.5 °C) -100 < TS ≤ 400 °C: ± (0.1% of reading + 0.5 °C) Reference Junction Compensation (R.J.C.): ± 0.5 °C
Burnout checking		Displaying warning when Thermocouple has failed
Unit of temperature measurement		Switchable °C and °F
