Product Description

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

Multiple (up to 10) standard resistors.

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