Honeywell FC-TPSU-2430 DC/DC Power Converter
Configured for power conversion and loop distribution in Honeywell Safety Manager networks, the FC-TPSU-2430 DC/DC power converter provides reliable physical and electrical execution. The conformal-coated module accepts an input voltage ranging from 18 to 36 VDC and delivers a regulated 30 VDC output at 1 A to power compatible field termination assemblies and instrumentation.
Power Conversion & Electrical Protection
The internal switching architecture features short-circuit current limiting, overvoltage protection, and 1500 VDC isolation to safeguard control system sub-racks. Standard DIN rail mounting geometry supports rapid installation inside industrial process automation control cabinets.
Loop Measurement Accuracy
Process control and safety instrumented systems demand stable supply voltages and low electrical noise profiles to preserve loop measurement accuracy. The module provides regulated 30 VDC auxiliary power with 1500 VDC isolation, effectively preventing ground loops and transient noise from propagating into analog input circuits. Low output ripple under 0.1 V RMS ensures clean voltage delivery to HART-enabled 4-20 mA field transmitters, preserving frequency-shift keying digital communications without signal distortion.

Field Installation Guidelines
Mount the converter securely onto a standard TS32 or TS35 x 7.5 mm DIN rail inside the instrument cabinet. Fasten mechanical end anchors on both sides of the module to prevent lateral displacement caused by industrial machinery vibration.
Route 24 VDC primary input power cables and 30 VDC output supply cables through separate wire ducts. Strip incoming conductors to 7 mm and connect them to the dedicated screw terminals, ensuring proper wire gauge selection up to 2.5 mm2 (AWG 14) and tightening screws to 0.5 Nm torque.
Land the panel earth conductor onto the designated chassis ground terminal to establish low-impedance grounding. Verify input supply polarity and measure output voltage under no-load conditions prior to energizing connected field termination assemblies.
Frequently Asked Questions
Q: How does the power converter respond to a sustained short circuit on its output load terminals? A: The converter incorporates built-in short-circuit protection that clamps output current below 3.3 A, preventing thermal damage to the internal power stage and automatically resuming normal 30 VDC regulation once the fault clears.
Q: What is the primary function of the 30 VDC output provided by this module? A: The regulated 30 VDC output provides isolated DC power to specific Honeywell Safety Manager field termination assemblies and field transmitters requiring loop supply voltages above standard 24 VDC rails.
Q: Can this unit operate reliably in unconditioned field control cabinets? A: Yes, the unit features a conformal-coated printed circuit board assembly and operates across an extended ambient temperature range of -40 to 70 deg C, offering resistance to moisture and atmospheric contaminants.
