Overview

The TC-4 for Experimental / LSA aircraft is a 2 1/4" Sunlight readable 4 channel thermocouple color display instrument.

Instrument can be configured for 5 different temperature display screens. The display can be configured to group EGTs and CHTs to common settings or each thermocouple channel can be independently displayed with individual programmable high alarm and probe type. The TC-4 also has a trend graph and maximum values display screen.

The TC-4s high accuracy is due to its built in thermocouple linearization curves and cold junction compensation techniques. Temperature probes can be common J, K or E type thermocouple probes as used in CHT and EGT senders. Temperatures can be displayed in degrees Celsius or degrees Fahrenheit from -100C to 1200C (-148F to 2192F).

The TC-4 also features a built in engine leaning facility which allows the pilot to optimize the fuel mixture according to peak EGT temperatures as well as a cruise mode facility to provide instant identification of changing EGT/CHT trends.

The TC-4 can also be interfaced via the CAN bus to an external RDAC unit (Remote Data Acquisition Unit). This allows for easier installation as the RDAC unit is normally mounted in the engine compartment.

Reviews

Installed this instrument into my RV-9. All four cylinders were connected to the instrument with bayonet probes. It installed in minutes in a, now, unused locaction. I connected the wiring and the probes, turned it on and it fired right up indicating the current OAT. Used the manual to set it up for my desired displays and it was very easy. Im considering getting another for my EGTs.

Q&A

Q: Does this come with four CHT thermocouples? If not, which do you recommend for my Jabiru engine?

No, you will have to purchase CHT probes separately, please view see # 11-05562

Q: What type of plug attaches to the rear of this MGL Vega TC-4 unit? Or do the Thermocouplers attach directly to the rear?

The thermocouplers attach to the unit via a DB9 male connector.
