Overview Manuals Applications Performance Configuration & Programming Temperature Range

Features:

  • Handles sixty-four isolated, single-ended 0–5 VDC analog input points.
  • Refreshes the input image at a documented 10 ms rate.
  • Supports software-selectable 12-bit or 14-bit conversion.
This ordering code identifies the high-density isolated 0–5 VDC analog-input module with sixty-four single-ended points.

Its fast acquisition and selectable conversion depth suit large groups of process measurements that feed TMR logic.

Commissioning should confirm scaling, resolution, shunt resistors, ETP assignment and the isolation strategy recorded in the project.

Availability is subject to Apter Power inventory and sourcing confirmation.

  • Aggregates dense banks of 0–5 VDC instrumentation in high-availability control cabinets.
  • Reads 0–20 mA transmitter loops through the specified 250-ohm input shunt.
  • Supports fast-changing process measurements where a 10 ms input refresh is required.
  • All sixty-four single-ended inputs are updated on the documented 10 ms acquisition cycle.
  • Programmable 12-bit or 14-bit conversion lets the project select the required measurement detail.
  • The isolated channel arrangement consolidates a large input count without sharing the non-isolated 3701 architecture.
  • Resolution is selected in the engineering configuration and must match the active application database.
  • Current-loop service uses the documented 250-ohm shunt to convert 0–20 mA into the voltage input.
  • Configured channel assignments must correspond to the external termination panel and interface cable.
  • Measurement accuracy is specified below 0.15% of full scale from 0°C to 60°C.
  • Temperature limits apply to the complete installed module and termination arrangement during operation.
  • Cabinet thermal conditions should be confirmed before the module is used at the edge of its stated range.
Description
Triconex 3720 provides sixty-four isolated, single-ended analog inputs for 0–5 VDC measurements in a TMR controller. Its triplicated acquisition structure carries each field value to the main processors while maintaining channel isolation at the module interface. The module therefore combines a large measurement population with the independent signal boundaries required by installations that separate field circuits at the input interface.

The high point count suits installations that must bring a large set of analog process variables into one chassis position. Selectable conversion resolution lets the engineering configuration balance measurement detail with the required response behavior. This makes the hardware appropriate for process areas where measurement separation and efficient use of chassis capacity are both important engineering considerations.

External termination hardware completes the path from field wiring to the backplane. Planning a replacement requires the existing resolution selection, current-conversion shunts and channel reference scheme to be preserved with the correct interface cable. Those selections should be recorded before maintenance so the replacement reproduces the intended conversion behavior, wiring separation and connection path without introducing hidden differences.

Technical notes
3720 resolution is programmable; preserve the 12/14-bit setting and verify the isolated single-ended termination path before moving channel data.
