Q1: What is the Honeywell 51303932-426 (MU-TSIM12) used for?
It is a single-channel Serial Interface FTA for Honeywell DCS systems, providing Modbus RTU communication between the control system and third-party field devices over EIA-232 or EIA-485 .
Q2: What protocol does it support?
Modbus RTU. It supports standard function codes including 01, 02, 03, 04, 05, 06, 08, and 16 .
Q3: What physical interfaces are available?
EIA-232 (RS-232) and EIA-485 (RS-485). EIA-485 operates in two-wire, half-duplex mode .
Q4: How many devices can be connected?
Up to 15 devices per FTA on an EIA-485 network. EIA-232 is point-to-point only .
Q5: What is the maximum cable distance?
EIA-232: 15 m (subject to 2500 pF capacitance limit). EIA-485: 1.2 km (4000 ft) .
Q6: Is this FTA CE compliant and conformally coated?
The 51303932-426 is CE compliant and not conformally coated .
Q7: Does it support redundancy?
No. Redundancy is not supported for this FTA .
Q8: What are the supported baud rates?

Q9: What terminal type does it use?
DB25 connector or compression terminals, Size A (6 inches / 152 mm) .
Q10: Is this a current or legacy product?
The TDC 3000 / TPS / Experion PKS is a legacy/mature platform. Confirm current availability and lifecycle status with Honeywell or an authorized distributor.
| Model | Description | When to Choose |
|---|---|---|
| 51303932-426 (MU-TSIM12) | Serial Interface FTA, Modbus RTU, CE compliant, non-coated | When Modbus RTU integration is required with CE compliance in standard environments |
| MU-TSIM13 | Extended-Range Modbus FTA | When extended address range or additional capability is required (confirm with Honeywell) |
| 51303932-428 (MC-TSIM12) | Modbus FTA, CE compliant, conformally coated | When conformal coating is required for harsh environments (confirm exact part number with Honeywell) |
| 51303932-403 (MU-TSIA12) | Serial Interface FTA for Allen-Bradley DF1 | When Allen-Bradley PLC integration is required instead of Modbus |
