The IC200ALG620 is an intelligent, 4-channel, 16-bit high-precision analog input RTD module designed for the GE VersaMax series. Requiring no external power supply, it autonomously generates and matches the correct excitation current for various 3-wire and 4-wire RTD sensors, including Platinum, Nickel, Copper, and Nickel/Iron. Users can individually configure each channel, select resistance ranges between 0-500 and 0-3000 ohms, and choose to output data as raw resistance or in tenths of degrees Celsius or Fahrenheit.
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
The module features robust monitoring that real-time reports high/low, under/over-range, open wire, and input short circuit alarms to the PLC. It offers two data acquisition rates optimized for 50 Hz and 60 Hz line frequencies to suppress ambient electrical interference.
Additionally, the module performs an automatic A/D calibration at powerup and repeats this process periodically during operation, effectively eliminating measurement drift caused by ambient temperature changes to ensure long-term data stability.
The mechanical enclosure of this module features a tool-free click-in structure that locks onto standard VersaMax carriers, completing all data communication and logic interaction via the internal backplane bus. Its hardware architecture includes high-isolation electrical protection circuitry, preventing external surges or ground loop noise from transmitting to the core PLC central processing unit.
The module retains channel configurations even during power loss. In the event of a field hardware replacement, a new module automatically receives parameter downloads from the controller the moment it is plugged into the carrier and powered up, achieving industrial-grade module replacement and plug-and-play functionality.

Oil and Gas Industry
Used for monitoring bearing temperatures at pumping stations along long-distance pipelines and real-time monitoring of multi-point temperatures within crude oil storage tanks.
Thermal Power and Heating Industry
Used for the precise measurement of boiler feedwater temperatures, steam pipeline wall temperatures, and medium temperatures within urban district heating exchange stations.
Pharmaceutical Machinery Industry
Used for internal temperature verification of autoclaves and precise control of shelf temperatures in pharmaceutical freeze dryers (lyophilizers).
Metallurgy and Metal Processing Industry
Cyclicly collects multi-point temperatures in industrial heat treatment furnaces (such as annealing and quenching furnaces) to ensure uniform heating of metal materials.
Plastics and Rubber Molding Industry
Used for precise closed-loop temperature control of multi-stage heating zones in injection molding barrels and heating platens in rubber vulcanizing machines.
Lithium-ion Battery and New Energy Manufacturing Industry
Performs high-density multi-point temperature compliance monitoring in battery cell high-temperature aging rooms and vacuum baking ovens.
If an IC200ALG620 module is configured to measure 0-500 or 0-3000 Ohms resistance, and the actual resistance is at the low end of the range, then the analog-to-digital conversion produces zero (a short circuit). When this occurs, the module reports the configured Channel Default value from the Input Parameters tab of the module configuration. If configured for 0 500, this happens below 2.9 Ohms. If configured for 0-3000, this happens below 22.1 Ohms.
The IC200ALG620 has four RTD channels. When all four channels are configured to inactive mode, head-ends including CPUs or NIUs will report a “loss of IO module” fault that points to the IC200ALG620 itself. To avoid this fault, you should configure at least one channel as active. When IC200ALG630 or IC200ALG620 modules are present in GNIU or PNIU rack and a 'Clear all' command is issued from Machine Edition software, Machine Edition may get disconnected, displaying timeout error "error 8097 - host disconnect has occurred".
When this error is logged, the Configuration is still cleared. To avoid this error “Request Timeout” value in “Additional Configuration” in “Target Properties” should be increased to 30s or more.
The General Electric IC200ALG620 is a 4-channel Analog Input RTD Module from the VersaMax series. It captures resistance signals from field RTD sensors and converts them into digital data for the PLC. Each channel integrates electrical isolation and utilizes hardware-level filtering within the enclosure to suppress electromagnetic cross-talk and high-frequency noise from long-distance transmission, ensuring continuous and stable process temperature acquisition.
It is a 4-channel, 16-bit high-precision analog input module within the GE VersaMax PLC series, specifically designed for temperature measurement by connecting to RTD (Resistance Temperature Detector) sensors.
How do you use the IC200ALG620?
Plug it into a corresponding VersaMax carrier, connect the RTD sensor cables, and configure the channel types via Proficy Machine Edition software. The PLC can then directly read the converted digital temperature values.
What types of RTD sensors does the IC200ALG620 support?
It supports Platinum (25/100/1000 ohms), Copper (10/50/100 ohms), Nickel (100/120 ohms), and Nickel/Iron (604 ohms) sensors.
How many input channels does the IC200ALG620 have?
The module provides 4 fully independent input channels.
What wiring configurations does the IC200ALG620 support?
It supports 3-wire and 4-wire RTD wiring methods to compensate for lead resistance errors in long-distance cables.
