TP857 (3BSE030192R1) is a dedicated DIN‑rail mounting baseplate built for the ABB AC 800M / 800xA DCS platform. It exclusively accepts the CI857 INSUM communication interface module, delivering ModuleBus signal routing, power distribution, and physical mechanical mounting within control cabinets. This baseplate establishes shielded signal paths and power terminals for stable INSUM field‑device communication, widely deployed in power generation, petrochemical, pulp‑and‑paper and heavy‑process manufacturing sites. OEM status: Obsolete original manufacturing; units are sourced via global procurement portals as new‑surplus or refurbished spare stock.
Core Technical Specifications
- Manufacturer Part Number: TP857 / 3BSE030192R1

- Compatible System: ABB AC 800M Controller, System 800xA; minimum firmware revision AC 800M V5.1
- Power Supply: 24 VDC (±20 %), max 5 W total power consumption with CI857 installed; rated current 200 mA @24VDC
- Isolation: 500 VAC isolation between ModuleBus and power domain
- Mechanical: Standard 35 mm DIN‑rail mounting; dimensions 119 mm W × 132 mm H × 45 mm D; weight approx. 0.3 kg; reinforced polycarbonate housing
- Connectors: 2‑pin power terminal, 12‑pin shielded ModuleBus connector, 9‑pin D‑Sub INSUM port, dedicated protective‑earth screw terminal
- Environmental: Operating temperature −25 °C ~ +70 °C; storage −40 °C ~ +85 °C; humidity 5‑95 % non‑condensing; vibration resistance 1 g (10‑500 Hz); IP20 (cabinet‑mounted)
Key Features
- Purpose‑built hardware carrier for CI857 INSUM interface, cannot operate standalone without the matched communication module.
- Integrated shielded ModuleBus and INSUM field‑port routing to reduce EMI interference in electrically noisy plant environments.
- Secure DIN‑rail locking mechanism plus dedicated PE grounding point for cabinet‑level noise suppression.
- Compact footprint optimizes cabinet space for retrofits and spare‑part replacement on legacy AC 800M installations.
Incoming Quality‑Check Procedure
- Visual inspection: Examine housing for cracks, burn marks, bent D‑Sub pins, damaged terminal screw blocks and PCB edge wear.
- Part‑label validation: Cross‑check printed part number 3BSE030192R1 against hardware marking; confirm no label tampering or overlay stickers.
- Connector continuity: Inspect ModuleBus, power terminals and 9‑pin D‑Sub for bent or recessed pins.
- Compatibility cross‑reference: Confirm target controller firmware meets minimum V5.1 requirement before installation.
- Power‑on bench test: Fit CI857 module, apply 24 VDC supply, verify module presence indication within 800xA hardware diagnostic tree.
Critical Technical Warnings & Procurement Notes
- This baseplate works only with . It is not interchangeable with other AC800M communication module baseplates; mismatched hardware will cause communication drop‑out or hardware fault codes.
- Firmware mismatch between AC800M controller and /TP857 assembly will trigger offline status; verify target site firmware revision prior to order placement.
- For refurbished units, inspect D‑Sub INSUM port for pin corrosion; field‑side port damage is a common failure mode on used hardware.
- Obsolete OEM production; lead times vary widely depending on global stock availability. Plan adequate turnaround for customs documentation and import clearance.
- Do not hot‑plug the INSUM D‑Sub cable under full process load; disengage field‑side power before connecting or disconnecting the 9‑pin connector.
Frequently Asked Questions
Q: Can TP857 run without module installed?A: No. TP857 is purely a mounting and routing baseplate; all INSUM communication functions reside on the interface module.
Q: Does this baseplate support hot‑swap?A: Physical hot‑removal from DIN‑rail is mechanically possible, but full process interlock and field‑device power shutdown is strongly recommended before removal to avoid INSUM bus communication collapse.
Q: What happens if I use controller firmware lower than V5.1?A: The ‑ assembly will not be recognized by the AC800M controller, showing unknown hardware in system diagnostics. Firmware upgrade of the controller is mandatory.
Q: Is 3BSE030192R1 the only order number for ?A: Yes, 3BSE030192R1 is the unique material designation for baseplate; no alternate OEM part numbers exist for this hardware.
