Recommended replacement model (noua generatie Phoenix)

MACX MCR-T-UI-UP, Comanda nr.: 2811394

Supports RTD / thermocouple / Voltaj / current multi-input, enhanced isolation, fully configurable; mechanically compatible for rail installation, the mainstream replacement for this series.

Note importante

1. 2814113 is a factory pre-configured fixed-range version, not a blank programmable base module. Do not directly replace it with 2814090 because the range settings differ.
2. When purchasing second-hand spare parts, verify the input type, wiring method and output signal upon receipt.
3. Software: MCR configuration software can read and verify internal parameters (legacy MCR configuration tool).

Tabel de comparație: 2814113 (MCR-T-UI-E) VS 2811394 (MACX MCR-T-UI-UP)

✅ Critical Risk Reminder: It fits on the DIN rail mechanically, but terminal pinout is NOT compatible. Do not connect wiring directly without modification!

2. Standard Wiring for 2814113 (MCR-T-UI-E), Pt100 3-wire

Terminal definition per original drawing

1, 2, 3: RTD input (3-wire Pt100)

1: One end of RTD

2: Compensation wire (for 3-wire measurement)

3: The other end of RTD

5, 6: Analog 4-20mA output (5+, 6-, current loop to PLC AI)

11, 12: Sursa de alimentare DC24V (11=24V+, 12=0V/GND)

Remarcă: 2814113 is pre-configured, no DIP switch setting required. Power on and ready: -200℃ = 4mA, 850℃ = 20mA

3. Wiring of Replacement 2811394 MACX MCR-T-UI-UP (Target setting: Pt100 3-wire, -200~850℃, 4-20mA)

RTD 3-wire sensor: 4.1 /4.2 /4.3 (RTD input)

Analog current output: 2.1(OUT+), 2.2(OUT-) → PLC 4-20mA AI channel

Alimentare electrică: 1.1=24V+, 1.2=GND

2.3/2.4: Threshold relay contacts (leave unused if not required)

Strip length 7mm, tightening torque 0.5~0.6Nm, conductor 0.2~2.5mm²

4. Commissioning Procedure for On-site Replacement
5. Opriți: Cut power to the module, sensor and PLC; mark and label all wire numbers
6. Remove old module from rail and clip 2811394 to the same rail position
7. Rewire according to new terminal definition; confirm the 3-wire Pt100 compensation core is not swapped
8. Prepare PACTware + MACX DTM, Phoenix USB configuration cable (2902829)
9. Porniți, connect software to module and download parameters:

Senzor: Pt100, IEC60751, 3-sârmă

Gamă: Lower limit -200℃, upper limit +850℃

Mod de ieșire: 4…20mA, redirecţiona (low temperature = 4mA, high temperature = 20mA)

Filtra: default 0.5s (increase value for heavy interference)

Releu: disable threshold function if not needed

6. Calibrare & verification (obligatoriu)

Cold junction check: Compare Pt100 resistance and PLC current reading at ambient temperature

Simulation test: Use resistance box to simulate Pt100 resistance values, verify 4mA /20mA endpoints

7. Save parameters into module, power cycle and re-test to confirm parameters are retained after power loss
8. Archive parameter record, replacement complete
9. Lista de verificare pentru depanare (applies to both old and new modules)

Fixed 4mA output: Sensor open circuit, broken 3-wire compensation line, loose sensor terminals

Ieșire fixă ​​de 20 mA: Input short circuit, Pt100 resistance out of upper limit

Instabil / citire fluctuantă: Sensor cable routed together with power cables, ground interference; check isolation and single-end shield grounding

New module cannot be detected by software: USB driver, DTM version, tensiune de alimentare insuficientă, terminale libere
