WAGO (Germantown, WI) has introduced an addition
to its power supply line designed for isolation amplifiers
and signal conditioners. The EPSITRON 787-2852
shares a common profile with JUMPFLEX 857 and 2857
Series signal conditioners enabling the output voltage to
be directly commoned, eliminating the need for additional
wiring. Features include:
■ Availability with a nominal output voltage of 24 VDC
and capacity of 24 W.
■ An integrated redundancy diode.
■ A pluggable picoMAX female connector.
■ LEDs and an active DC OK signal for clear status
■ An input range from 85 to 264 VAC.
■ Approvals including cULus, ATEX/IECEx, and UL
Class 1, Division 2.
Single In-Line High Voltage Reed Relay
Standex-Meder Electronics (Cincinnati, OH) has
