Meter Relays
How we set the pace in the race. Relays without delays. Style. Performance. Versatiltiy. Direct Drive.
Optemp. Optronic. Two models: The Deede MR2. The Beede MR4. The MR2 is characterized by a
centrally-located, dual concentric, setpoint control kob assembly and full view set pointers.
The MR4 by offset control knobs with gear-driven set pointers neatly recessed behind
the dial for more accurate set pointer positioning. They come in two cases: The Centurion
with molded high-impact Noryl resin (N-190) case and glass window for tough spots.
The QA with a clear Lexan front for where it's friendlier.
Both come in 3" or 4" cases. Both have optical, non-contacting set points with continuous
indication. The solid state optics are completely immune to light. They come as a
complete unit with integral power supply and relays, or as a meter with set pointers and
optical switching elements only. The IRLED light sources are solid state for long life.
The setpoint control knobs are designed for rough handling. Both have a coincidence within
1% of full scale over the operating span, and indication accuracy of ±2% of full scale, ±1%
optional. Deadband of 0.5%. Ambient temperature range of -20°F to +165°F.
Silver cadmium oxide, gold finished contacts rated 5 amps A.C. resistive @ 115 to 230 VAC.
Isolation voltage of 1500 VRMS, rear terminals to panel.
Powwer requirements of 115/230 VAC @ 47 to 63Hz. 12 to 24 optional. Power consumption of 5 watts max.
Standard Relay operating logic for all Beede controllers is "Failsafe Mode".
