Applications
The TMV 2-1205SHI is used in industrial process control equipment, PLC backplanes, and motor drive gate isolators where 5200 VDC I/O galvanic isolation protects sensitive low-voltage circuitry from high-voltage rail transients. Medical device power supplies benefit from its high isolation rating and 2 W capacity for powering isolated analog front-ends or sensor interfaces. Fieldbus and RS-485 repeater boards also use this module to isolate communication grounds across hazardous-area barriers.

Frequently Asked Questions
What is the I/O isolation voltage rating of the TMV 2-1205SHI and why does it matter for industrial designs?
The TMV 2-1205SHI provides 5200 VDC input-to-output isolation, which is sufficient to meet IEC 61010 and IEC 60950 requirements for reinforced insulation in industrial control and measurement equipment. This high isolation rating protects microcontroller or DSP circuitry on the secondary side from voltage spikes and ground faults originating from motor drives, welding equipment, or high-voltage bus systems on the primary side.
How wide is the input voltage tolerance of the TMV 2-1205SHI, and what does this mean for unregulated 12 V bus applications?
The TMV 2-1205SHI accepts a ±10% input voltage variation around its 12 V nominal input, meaning it operates correctly from approximately 10.8 V to 13.2 V. This tolerance accommodates typical unregulated 12 V bus sag and overshoot in industrial equipment without requiring an additional pre-regulator, simplifying the power architecture and reducing total BOM cost.
What PCB mounting and package format does the TMV 2-1205SHI use, and how does it affect assembly?
The TMV 2-1205SHI uses an encapsulated SIP-7 (Single In-line Package, 7-pin) through-hole format, which simplifies PCB insertion and wave soldering in standard industrial manufacturing lines. The encapsulation provides mechanical protection against vibration and humidity ingress, making it suitable for harsh-environment PCBs in factory automation, transportation power systems, and outdoor control panels.
Can the TMV 2-1205SHI power an isolated RS-485 transceiver in a fieldbus network?
Yes, the TMV 2-1205SHI delivers 2 W at 5 V with 5200 VDC isolation, which is more than sufficient to power isolated RS-485 or CAN transceivers that typically draw 50 mA to 200 mA at 5 V. Its ±10% input tolerance handles the variable 12 V supply rail found in PLC cabinets and field junction boxes, ensuring reliable communication isolation across a fieldbus network even during load transients.
