Honeywell TC-SMPD01 SIM FTA Power Adapter 24 VDC

The Honeywell TC-SMPD01 is a 24 VDC SIM FTA Power Adapter used in Honeywell Serial Interface Module (SIM) configurations. It provides the external DC power connection required by the SIM-to-FTA interface arrangement, supporting communication between a Honeywell serial interface module and its associated field termination assembly (FTA).

Technical Specifications

Function and System Configuration

The TC-SMPD01 forms part of the Honeywell Serial Interface Module hardware configuration. It is used with the TC-MUX021 serial interface module and the TC-KSM003 SIM-to-Power Adapter Cable to establish the power connection between the adapter and the SIM assembly.

The adapter supports the external power arrangement for serial interface configurations using compatible FTAs, including Modbus and Allen-Bradley DF1 interfaces. The associated FTA and cabinet cable must be selected according to the communication interface and installation arrangement.

Power Supply and Installation Requirements

The 24 VDC supply must be a dedicated floating power source used exclusively for the TC-SMPD01. Honeywell warns that sharing the supply with other equipment or using a non-floating source can introduce voltage transients that may damage the associated TC-MUX021 SIM.

For installation, the 24 VDC supply connects to terminal block J5 with correct polarity. The SIM-to-Power Adapter Cable connects to J1. The adapter can be mounted on a user-supplied DIN rail or directly on a suitable flat mounting surface.

Compatible Components

The documented SIM configuration includes the following components:

• TC-MUX021: Two-channel Serial Interface Module.
• TC-KSM003: 3 m SIM-to-Power Adapter Cable.
• TC-SMPD01: 24 VDC SIM FTA Power Adapter.
• TC-SMPC01: Alternative SIM FTA Power Adapter rated for 85-265 VAC.
• MC-TSIM12: Modbus Field Termination Assembly.
• MC-TSIA12: Allen-Bradley DF1 Field Termination Assembly.
• MU-KLAMxx / MU-KSXxxx: Internal or external cabinet cables, respectively.

Frequently Asked Questions

Q: What is the function of the Honeywell TC-SMPD01?

A: It provides the 24 VDC power connection for the SIM FTA configuration, connecting to the Serial Interface Module through the dedicated adapter cable.

Q: Can the TC-SMPD01 use a shared 24 VDC power supply?

A: No. Honeywell specifies a dedicated floating 24 VDC supply for this adapter to prevent voltage transients that could damage the associated SIM.

Q: Can the TC-SMPD01 replace the TC-SMPC01?

A: Both serve as SIM FTA Power Adapters, but their power input requirements differ. The TC-SMPD01 is the 24 VDC version, whereas the TC-SMPC01 is the 85-265 VAC version. They should not be treated as electrically interchangeable without changing the power supply arrangement.
