DESCRIPTION
The TDH-8070/71 Time Delay Relays have been designed with thick film hybrid microelectronics timing circuits
and MIL-PRF-6106 relays, packaged in a hermetically sealed military style enclosure. The TDH-8070/71 series
are qualified to MIL-R-83726/29 and designed to withstand severe environmental conditions encountered in
military/aerospace applications. These relays are suited for use in power control, communication circuits and
many other applications where power switching and high reliability are required over a wide temperature range.
