DESCRIPTION
The Veris VTD Series are multi-function time delay relays equipped with an external
control switch input and designed for easy socket/DIN mounting. The VTD2P-F50
includes five functions shown at left, while the VTD1P-UNI and VTD2P-UNI include
the same five as the VTD2P-F50 plus five more, for the most versatile relay available.
Save inventory costs by purchasing one relay for all the functions you need.
FEATURES
●
VTD2P-F50 has thumb wheel adjustment for function and timing...ensures
accuracy and eliminates mechanical deviation
●
VTD1P/2P-UNI models are made with solid state relays for greater reliability
●
Two different housings provide multiple mounting options
