Transmitters with inputs for voltage and current sensors

Connectors are included.

GS42/GS42E Wired sockets for 2 x voltage/current inputs with sensor supply. Also has the option to be powered from an external 9VDC regulated supply if the sensor supply is not used (when used like this, the transmitter is referred to as a GS42E). GS-31
GS44/GS44E Wired sockets for 4 x voltage/current inputs, sensor supply and external supply switch. When configured for external power connection the transmitter is referred to as a GS44E.
GS44AVE The GS44AVE is intended for use with any sensor where an averaged rather than instantaneous value at the time of transmission is required. The averaging technique includes values that can change during a transmission interval. At the point of transmission the averaged value of the last 30 values, sampled every 10 seconds per channel, is sent.
External power supply type MP9U is included.
