More Information

Overview Manuals Applications Certifications Installation Operating Environment

Features:

  • Provides eight individually isolated 4-20 mA input channels.
  • Supports field-powered and locally powered current loops.
  • Adds input conditioning and surge protection ahead of the electronics module.
The current ordering configuration is 1C31227G01, the current-input personality module used with Ovation electronics module 1C31224G01 for eight 14-bit channels.

It receives 4-20 mA field signals, supports either field or local loop power and passes conditioned data to the Ovation Serial I/O Bus through the electronics module.

Before commissioning, verify the exact electronics-module pairing, the loop-power source, terminal connections and single-point shield grounding for every channel.

Availability is subject to Apter Power inventory and sourcing confirmation.
Verified resources for Emerson 1C31227G01: Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
  • Measures eight 4-20 mA process-transmitter loops in an Ovation I/O cabinet.
  • Supports locally powered current loops supplied from the cabinet auxiliary 24 VDC source.
  • Supports field-powered current inputs where loop power is provided outside the cabinet.
  • The 4-20 mA configuration is the CE Mark-certified arrangement in this analog-input group.
  • The cited certification applies to the documented current-input pairing, not the voltage-input variant.
  • The installed system must retain the wiring and enclosure conditions referenced by the Ovation manual.
  • Use shielded twisted-pair wire for every current-input field connection.
  • Select the terminal positions for field power or local power exactly as shown on the module label.
  • Bond the input return and cable shield at the cabinet or field device without creating a second grounding point.
  • The subsystem is rated for operation from 0 to 60°C.
  • Storage is permitted from -40 to 85°C before installation or service.
  • Relative humidity must remain between 0 and 95% without condensation.
Description
1C31227G01 is the current-input personality module in an Ovation 14-bit analog-input subsystem. It provides eight individually isolated 4-20 mA channels when combined with the matching 1C31224G01 electronics module.

The module conditions current-loop signals, routes them to the electronics module and provides surge protection for the input circuits. It supports both field-powered devices and local loop power from the 24 VDC auxiliary supply.

Confirm the 1C31224G01 pairing, loop-power method, terminal designations and shield grounding before installation. The current-input configuration is the CE Mark-certified member of this module group.

Technical notes
Use 1C31227G01 only with the 1C31224G01 electronics module, and verify 4-20 mA loop power source, isolation, polarity, and auxiliary 24 VDC wiring.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Which input signal does 1C31227G01 accept?
It is the eight-channel personality module for 4-20 mA current inputs.
How does 1C31227G01 fit into the documented analog-input card pair?
The official subsystem table pairs it with 1C31224G01.
Can 1C31227G01 power a transmitter loop locally?
Yes. The documented arrangement can use the internal 24 VDC auxiliary source or a field-powered loop.
Which field-wiring practice applies to 1C31227G01 analog input channels?
Use shielded twisted-pair cable and apply the terminal and grounding arrangement shown in the Ovation manual.
Can a different 1C31227 revision replace 1C31227G01 without matching its input function?
No. G01 is the current-input version; the voltage-input G02 has a different range and wiring.
What must be confirmed when requesting a 1C31227G01 quotation?
Confirm the exact G01 suffix, matching electronics module, loop-power method and required quantity.
