MCR-T-UI-E Replacement DIN Rail Enclosure | 17.5mm Width Signal Isolator & Temperature Transmitter Module Shell
In industrial process control, chemical explosion-proof systems and temperature measurement projects, Phoenix Contact MCR-T-UI-E is a mainstream 3-way isolation temperature transmitter module, widely used for thermocouple, RTD signal conversion and galvanic isolation. However, genuine Phoenix MCR-T-UI-E housings face high procurement cost, long overseas delivery lead time and limited stock supply, which seriously restricts mass production delivery for domestic signal module manufacturers.
Our fully interchangeable MCR-T-UI-E compatible DIN rail enclosure solves this pain point perfectly. It adopts 1:1 copying of original size, internal PCB positioning structure, terminal window and DIN rail buckle design, supporting direct assembly of signal isolators, intrinsic safety barriers and 4-20mA temperature transmitter PCBs without circuit board redesign or mold modification.
What Is MCR-T-UI-E Compatible DIN Rail Module Housing?
The original Phoenix MCR-T-UI-E module adopts standard 17.5mm width DIN rail structure, overall dimension: 17.5(W) × 99(H) × 114.5(D)mm, RAL6021 green PA polyamide shell, dedicated for 3-isolation temperature signal conditioning circuitsPhoenix Contact USA.
Our replacement enclosure fully matches all structural parameters of MCR-T-UI-E:
- Exact identical overall dimension, internal PCB standoff height, upper/lower shell lock buckle;
- Front double-side terminal window reserved, compatible with pluggable screw PCB terminals (2EDG/KF series) consistent with original wiring port layout;
- Side vertical heat dissipation grille design, consistent air convection channel as genuine housing to avoid signal drift caused by heat accumulation;
- Integrated spring metal DIN rail buckle, perfectly snap onto NS35/7.5 & NS35/15 standard DIN rails;
- Pre-reserved PCB fixing screw posts, compatible with standard 2/3/4-wire RTD & thermocouple isolation circuit layout.
Standard color options: RAL6021 industrial green (direct substitute for original), customized gray, black, transparent top cover available.
Core Advantages Of MCR-T-UI-E Replacement DIN Rail Enclosure
1. 100% Dimensional Interchangeable, Zero PCB Redesign Cost
The core competitive strength of our MCR-T-UI-E compatible module housing is full dimensional consistency with genuine Phoenix MCR-T-UI-E shell. All internal positioning posts, terminal opening size, shell lock structure and heat dissipation slots are produced per original drawing tolerance ±0.05mm. Electronics factories can directly reuse existing signal isolator / temperature transmitter / safety barrier PCBs, saving new mold opening, circuit layout revision and prototype testing cost, cutting product development cycle by over 60%.
2. UL94-V0 Flame Retardant PA66 Material, Industrial Explosion-Proof Safety Standard
Whole shell injection molded with high-toughness flame retardant PA66 nylon, reach UL94-V0 fire resistance grade, stable working temperature range -40℃ ~ +105℃. Excellent insulation creepage distance meets intrinsic safety Ex barrier design requirement, withstand 1500V AC isolation voltage for input/output/power three-way isolation circuit, fully compliant with IEC 61010-1 industrial signal module safety standard. Anti-aging, oil mist and chemical vapor corrosion resistant, stable long-term operation in chemical plant, oil field and outdoor power cabinet harsh environments.
3. Optimized Side Vertical Heat Dissipation Grille, Consistent Signal Accuracy
Copy original MCR-T-UI-E vertical side heat dissipation channel design, forming upper-lower air convection inside the shell. Effectively discharge heat generated by isolation transformers and DC-DC power chips, avoid internal temperature rise leading to signal drift and temperature coefficient deviation, guarantee measurement accuracy ≤0.1%FS for long-time continuous operation, fully matching heat dissipation performance of imported original housing.
4. Universal Compatibility With All Signal Conditioning Circuit Boards
Front double large terminal window supports all mainstream pluggable screw PCB wiring terminals: 2EDG, 15EDG, KF barrier series terminals. Split upper/lower shell with side snap lock, only need flat screwdriver to open and close, convenient for mass PCB assembly production line operation. Internal large-capacity cavity reserves sufficient space for three-way isolation circuit, DIP isolation transformers and DIP switch configuration components, suitable for programmable temperature transmitters, passive/active signal isolators and intrinsic safety barriers.
5. Obvious Cost & Supply Advantages Over Imported Genuine Shell
- Lower unit price: Domestic integrated injection molding production, unit cost only 35%-50% of original Phoenix MCR-T-UI-E housing, greatly reduce finished signal module BOM cost;
- Fast delivery cycle: Sufficient spot stock of 17.5mm MCR compatible green shells, bulk order shipment within 1-3 working days, no 4-8 weeks overseas lead time;
- Flexible customization: Support shell surface silk screen LOGO, custom ventilation hole layout, transparent observation window and special shell color without high minimum order quantity;
- Complete matching accessories: Supporting TBUS power bus connector, plastic end baffles and module marking labels one-stop supply.
