IC200ALG620 VersaMax Analog Input RTD Module 4 RTD with 16 bits of
resolution IC200ALG260 IC200ALG264 Fanuc GE
Product Description
The IC200ALG620 Analog Input RTD Module is an intelligent module
that accepts input signals from up to four RTD input devices and
provides input data with 16 bits of resolution.
No external power supply is required for this module. The
excitation current for the RTDs is provided by the module, which
automatically matches the excitation current to each configured RTD
type. The module accepts inputs from four independent 3-wire and/or
4-wire platinum, nickel, nickel/iron, or copper RTDs. Module
features include
▪ Selectable resistance measurements in tenths of ohms, tenths of
degrees Fahrenheit, or tenths of degrees Celsius ▪ Individual
channel configuration ▪ Selectable resistance ranges: 0 – 500 ohms
and 0 – 3000 ohms ▪ Selectable RTD input as resistance or
temperature (Celsius or Fahrenheit) ▪ Reports high/low,
under-range/over-range, open wire and input short alarms. ▪ Two
data acquisition rates based on 50 Hz and 60 Hz line frequencies ▪
Configurable channel activation The module automatically performs
A/D calibration at powerup. Automatic calibration is then repeated
periodically to compensate for changes in the ambient temperature.
LED Indicator
The OK LED indicates module status: ▪ On green indicates normal
operation ▪ Flashing green indicates boot mode or update ▪ Flashing
amber indicates self-diagnostic error ▪ Off indicates no 3.3V
backplane power.
