More Information

Overview Manuals Identity and Fit Load Engineering Service Checks Application
  • Use RH916TA as the exact FBM242 module identity
  • Keep module power separate from external field power
  • Match the termination assembly and Type 4 cable before wiring

Foxboro RH916TA executes the FBM242 function by providing sixteen isolated solid-state output paths for externally powered industrial DC loads.

It communicates with the control processor over redundant A and B Module Fieldbus paths and continues on the active path if the other path is switched or unavailable.

The RH916TA label identifies the electronic module; its termination assembly and field-power design must be selected separately for the installed load circuits.

Availability, condition, price, and shipping time for RH916TA are confirmed during quotation.

Description
Foxboro RH916TA executes the FBM242 function by providing sixteen isolated solid-state output paths for externally powered industrial DC loads.

It communicates with the control processor over the redundant module Fieldbus and can be applied in single or supported redundant configurations.

The RH916TA label identifies the electronic module; its termination assembly and field-power design must be selected separately for the installed load circuits.

Technical notes
RH916TA is an FBM242 electronic module, not a termination assembly despite the letters TA in the part number. Use module-body dimensions and weight only.

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.
Is Foxboro RH916TA a termination assembly?
No. RH916TA is the current electronic module order code for FBM242; the field termination assembly and cable are separate hardware.
Can Foxboro RH916TA replace another FBM242 order code directly?
Confirm controller release, baseplate, A/B Module Fieldbus support, TA/cable set and database hardware identity before treating another suffix as interchangeable.
Why can one Foxboro RH916TA output trip while neighboring channels remain active?
Each channel is isolated and separately protected, so inspect that load's field supply, current, inrush, wiring, suppression and short-circuit condition.
What field supply should be measured when Foxboro RH916TA outputs do not energize?
Measure the actual loaded 15 to 60 VDC supply at the TA and channel return, not only the module's 24 VDC electronics supply.
Can Foxboro RH916TA outputs be paralleled for more current?
Do not parallel channels unless an exact approved engineering document permits it; use a correctly rated interposing device instead.
What should be preserved before moving Foxboro RH916TA to a new slot?
Preserve the controller path, A/B Module Fieldbus status, output mapping, TA terminals, safe states, forcing status, field-supply groups and load records.
What final checks matter after installing Foxboro RH916TA?
Verify each load separately, monitor loaded voltage and current, test output-fault diagnostics and safe states, then verify communication over both Module Fieldbus paths and the intended process sequence.
