Simpson Controllers/Meter Relays

3-1/2" and 4-1/2" 33 Series "Rugged Seal" Meter Relays with Amplifier Input -- $300-$456

* Four models available for a wide variety of control, alarm, limit applications

* Photo conductor sensing eliminates all interference with the indicating meter

* Incorporates an amplifier input which drives a rugged high torque pivot and jewel or taut-band meter

* All voltage ranges are 20,000 ohm/Volt (50 µA) and all current ranges have a 50 mV drop

* "Rugged Seal" construction withstands rigorous environmental conditions

* High-gain transistor switch circuit provides accurate switching with a "dead band" of no more than 0.5% of full scale

* Fail safe circuitry opens output relays in the event of power failure

* Calibration Accuracy: ±2% of full scale

* Control Point(s) Adjustment: Single 0-100% of arc; Double (Low limit) 0-95% of arc., (High limit) 5-100% of arc; Adjustable to within 4š of each other

* Power: 108-132 VAC, 50-400 Hz

* Operating Temp.: 5 to 50°C

* Sealed metal case, plastic window

Model 3324AIXA Temperature Meter Relays -- $474-$483

* High impedance, solid-state circuit eliminates thermocouple lead length adjustments

* Thermocouple resistance may be anywhere from 0 to 100 ohms

* All ranges use Simpson's rugged 1 milliamp pivot-and-jewel meter movement

* Electronic cold junction compensation is standard

Model 3344AIXA Motor Load Meter Relays -- $433-$446

* Can be field adjusted to match the rated load current for a motor with the 100% mark on the scale

* Built-in adjustment potentiometer eliminates winding turns on current transformer

* Built-in time delay eliminates the need for external time delays or manual overrides

* Standard delay: 5 sec. Programmable 0-5 sec, using external resistor. Factory adjustable to 20 sec. Time delay occurs only when pointer is upscale of the setpoint, may be disabled with external jumper. No time delay on low setpoint

* Scale: green 0-100%, red 100%-150%
