PRODUCT DESCRIPTION
Selectable analogue inputs with 60 Hz interference rejection
ICS Triplex T3420A is the Regent analogue input module with 60 Hz rejection. It accepts sixteen single-ended or eight differential voltage signals, conditions and multiplexes them, and converts the measurements into twelve-bit data for the controller I/O interface.
Input range and operating mode are selected by internal jumpers and the matching software definition. Current signals require external precision conversion resistors, and transmitter loop power is supplied separately. Calibration must match the selected range and mode before the module enters service.

REGENT EQUIPMENT
Match T3420A to the documented Regent configuration
This Regent module measures analogue voltage inputs; current signals require the documented external resistor arrangement. Match the configured channel mode, voltage range, termination, references and external transmitter supply.
Match sixteen single-ended or eight differential inputs, the appropriate termination assembly and upper 9/lower 15 keys. Verify the selected voltage range, external current-conversion resistors and separate transmitter loop supply.
Select the standard-response module and correct single-ended or differential mode in WINTERPRET; verify scaling and voting.
Features:
- Sixteen single-ended or eight differential inputs
- Twelve-bit analogue conversion
- Selectable unipolar and bipolar voltage ranges
The ICS Triplex T3420A regent analogue input module requires the appropriate mounting, connections and configuration to be verified before system integration and commissioning.
INTERCHANGEABILITY
Verify the complete replacement identity before commissioning
Record the complete T3420A identity and compare its hardware revision with the installed item. Retain T3420A rather than assuming equivalence to the fast-response T3420AF. Check range and filter jumpers, software mode, field references and calibration together.
Match sixteen single-ended or eight differential inputs, the appropriate termination assembly and upper 9/lower 15 keys. Select the standard-response module and correct single-ended or differential mode in WINTERPRET; verify scaling and voting.
Use the controlled manufacturer procedure and the approved maintenance plan. The NOSIG indication has range-specific thresholds; not every out-of-range signal sets it. Use the correct manufacturer threshold table and site alarm logic.
Features:
- Complete order identity retained
- Companion equipment and configuration checked
- No unconditional substitution claim
The ICS Triplex T3420A regent analogue input module requires replacement verification against the complete installed configuration and current manufacturer documentation.

FREQUENTLY ASKED QUESTIONS
Questions buyers ask about T3420A
Direct answers about identity, compatibility, stock, warranty, payment and shipping.
-
How many analogue channels can be used?
Sixteen single-ended or eight differential inputs, depending on jumper and software configuration. Each group contains eight single-ended or four differential channels. -
Is T3420A the fast-response version?
No. T3420A is the 60 Hz rejection version. T3420AF has different filtering and response characteristics, even though both use the same channel-mode options. -
Can a 4-20 mA transmitter be connected without conversion components?
Current measurement uses external precision 250 ohm resistors. The documented 4-20 mA arrangement uses the 1-5 V range and requires the proper termination and transmitter loop supply. -
Does the module supply power to two-wire transmitters?
No. The manufacturer explicitly states that analog field-loop power is not supplied by the module. Provide the approved external loop supply and wiring. -
Does the 1.80 ms figure describe all signal response?
No. It is the repeating eight-channel differential update period. Filter response and controller access timing are separate; single-ended full-channel updates take 3.60 ms. -
When is calibration required?
The manual requires calibration when changing the operating voltage range or channel mode and once per year after installation. Follow the complete procedure with controlled field disconnection and process safeguards. -
Will every abnormal analogue value set NOSIG?
No. The manufacturer defines separate out-of-range thresholds for each selected range and warns that some out-of-range signals do not set NOSIG. Verify the actual range and alarm logic.
