PRODUCT DESCRIPTION
T7481A 24 V DC monitored guarded output module
T7481A is a Regent + Plus monitored guarded output module for 24 V DC field loads. Sixteen outputs are divided into two isolated groups, with redundant switching and automatic checks intended to detect internal faults and external load problems.
The module monitors open loads, short circuits and blown fuses while reporting channel status to the controller. Single-module and parallel-module arrangements have different fault responses, and the A variant supports lower minimum load current than the original T7481.

Manuals & support
REGENT + PLUS EQUIPMENT
Match T7481A to the documented Regent + Plus configuration
T7481A belongs to the Regent + Plus monitored guarded output family. It connects compatible 24 V DC field loads through sixteen outputs, arranged as two isolated groups of eight.
For the documented parallel arrangement, both modules require dual-mode configuration and the correct partner assembly and slot references. Uncoordinated output tests can otherwise report faults.
Load selection must include off-state leakage as well as on-state current. The lower-current A variant is not a reason to ignore load release voltage, fusing or field-power checks.
Features:
- Two separately powered output groups
- Configured single or parallel operation
- Load and fuse fault diagnostics
The ICS Triplex T7481A monitored guarded output module requires the appropriate mounting, connections and configuration to be verified before system integration and commissioning.
INTERCHANGEABILITY
Verify the complete replacement identity before commissioning
Retain the complete T7481A designation. The non-A T7481 has different low-current load and off-state leakage limits, so a matching family name alone does not establish interchangeability.
Confirm the supplied revision, field loads, chassis arrangement, fuses and application configuration against controlled site records. This page does not establish the revision of the stock offered.
Use the full manufacturer maintenance procedure and approved isolation plan. Online replacement is conditional on the documented fault-tolerant arrangement, not a blanket permission for live wiring work.
Features:
- Preserve the A suffix
- Check load and configuration compatibility
- Validate the approved maintenance arrangement
The ICS Triplex T7481A monitored guarded output module requires replacement verification against the complete installed configuration and current manufacturer documentation.

FREQUENTLY ASKED QUESTIONS
Questions buyers ask about T7481A
Direct answers about identity, compatibility, stock, warranty, payment and shipping.
-
What does the A suffix change on T7481A?
The manual distinguishes T7481A from T7481 by its lower minimum load current: 5 mA rather than 20 mA. Their off-state leakage limits also differ. Preserve the suffix when ordering. -
Which loads does the manufacturer describe?
The manual identifies solenoids, actuators and process interlock outputs. Check the actual field voltage, current and guaranteed off-state behavior before selecting a load. -
How many outputs and power groups are provided?
There are 16 outputs divided into two electrically isolated groups of eight. Each group has its own field-power terminals. -
Can one module provide fault-tolerant operation?
The documented fault-tolerant arrangement uses two modules wired in parallel and configured for dual mode. A single module is a different fail-safe arrangement; do not treat them as equivalent. -
What do load/fuse fault indications cover?
The diagnostics detect open loads, shorted loads and blown fuses. Missing field power can also cause all channels in that group to report load/fuse faults. -
Does disabling a fault LED stop load monitoring?
No. The configuration option suppresses the front-panel indication only. Fault monitoring continues and its status remains available to the controller. -
Which details matter before replacement?
Verify the complete part number, load behavior, field wiring, fuse type, fault-mode selection and single or dual configuration. Slot-key numbers are not reproduced here because the manual table uses inconsistent model labels.
