|Model SM series are a Potentiometer setting meter relays with dual Hi & Lo setting.
The setters are used multi-turns resistive potentiometers as preset buffers which setting
able to be read directly in display for switch selection. The input functions of the units are of
wide varieties & ranges, including many parameters of industry process and power system
as DCV, ACV, DCA, ACA, DC rate, temerature, Frequency, Speed, Load cell as standard
products. For wide application, with some external transducers, the series can be extended
to a wider field application as watt, var, power factor & etc.
The unit provides four digits display up to 9999 counts with find resolution & the displays are of high rate-super bringhtness LED,
Dual control outputs compliant Hi & Lo setting of SPDT relay contacts of an on-off control type. The outputs also comply delaying function
adjusted 0-30 seconds standardly & longer requirement for 0-60 or 0-120 secs based on specified request. Dead band also an option
availably is selectively & alternatively to time delayer.
Special design in meter front of an open-door type, convenient to preset & protects setting to avoid undesired changes
in field application.
