TH0240 Standard Resistance Multiplexer

1. Summary

TH0240 is a precise resistance channel-switch device, integrates ultra sensitive, high efficiency, polarized sealed relay, which can eliminate the self-heating effect in the relay. TH0240 improves the efficiency by eliminating the need to continually change leads when measuring groups of resistors.

2. Features

• 10 four terminal channels.

• Sealed Relays with 3 A carrying capacity.

• Copper tellurium terminal.

• Insulation resistance> 1012 Ω.

• The LED indicator on front panel is convenient for observing the selected channel.

• Front Panel or RS232 interface.

3. Application

☆ Establish automatic resistance measurement system

TH0240 Establish automatic resistance measurement system

• Multiple (up to 10) standard resistors.

• The channel of reference standard resistance can be automatically switched according to the value of measured resistance.
