These meters feature a clean line design that enhaces the look of your panel. Kinfe edge pointers and shadow free acrylic covers help to pinpoint values easily. Pointers for upper and lower limits are color codes for easy identification. The 196 Series Meter-Relays contain an exclusive light sensitive transistor switch that provides the ultimate in control simplicity and reliability. This switch controls the load relays with no pointer contacts or mechanical interference in the meter mechanism.

Meter relay Specifcations
Alarm Control: Each realy is engineered for on-off (automatic reset) control.
Power: 117 VAC operation (50 or 60 Hz), no special power supply needed
Lamp: Long lamp life, under rated voltage operated, 5 year life expectancy
Safe Operation: In case of loss of control power, setpoint relays immediately de-energize
Setpoint Coincidence ±2% of full scale at 117 VAC power
Repeatability: 0.3% of full scale
Setpoint Travel: 100% of full scale double setpoint can be positioned within 2 mechanical degrees of each other- 2.2% of full scale
Contact Rating: 5 AAC non-inductive at 120 V 5 ADC non-inductive at 28 V 0.2 ADC non-inductive at 125 V
Load Relay: DPDT per setpoint
Position of use: Vertical (scale) standard or to specified angle or position
Full scale deflection: 90 °
Full scale length:
21⁄2” 2.06”
31⁄2” 2.88”
41⁄2” 3.93”
Movement: Pivot and Jewel
In this design the coil and pointer are supported by polished steel pivots at each end which fit into jewel bearings. Pivot and jewel meters are recommended for high vibration environments because of the mechanism’s inherent stability and strength. Accuracy and repeatability are almost equal to the taut-band’s, and good performance from the pivot and jewel construction is the reason for its long popularity.
Case: ABS plastic, Black with grey back
Cover: Polycarbonate plastic cover and window.
Overload rating: 1 second- 1000% -DC A ; ≤ 100 VDC -1000%, >100 VDC @ 200% ; 150% AC A and ACV Continous – 150% except DCV @ 120%
