DESCRIPTION: The PSR-1 is a Light Sensitive Resistor that may be used as an input to indicate the presence of light at the sensor location. The PSR-1-T is a PSR-1 coupled with a B420-P transmitter. The PSR-1-T produces a 4 - 20mA output signal. The sensor is designed to be mounted in the end of a weatherproof conduit box. APPLICATION: The PSR-1 has a resistance in darkness in excess of 1 M/uni03A9 and resistance in bright light of less than 1.5 k/uni03A9. The PSR-1 and PSR-1-T indicate the presence or absence of light. They should not be used for foot-candle control of occupied spaces. The PSR-1-T is calibrated for 4mA in bright light > 100 foot-candles and 20mA in darkness < 0.1 foot-candles. SPECIFICATIONS: PSR-1 Output (non-linear) >1 M/uni03A9 in dark <1.5 k/uni03A9 in bright light Temperature -25˚C to 75˚C (-13˚F to 167˚F) PSR-1-T Power 12 - 35 VDC Max curr ent draw 22mA Output (linear) 4 - 20mA (current limited to 22mA) Temperature -25˚C to 75˚C (-13˚F to 167˚F) PSR: PRODUCT ORDERING INFORMATION Power Supply 4-20mA loop Device AE-LPI-X + - LPI + LPI - LCD PWR + OUT - + - DDC + - LOOP POWERED INDICATOR-EXECUTIVE ENCLOSURE SERIES DESCRIPTION: The AE-LPI-X is a loop powered indicator in an executive space enclosure.

DAMPER END SWITCH - DES-100 SERIES DESCRIPTION: The damper position switch is a mechanically activated electrical switch which provides accurate and reliable indication of damper blade position. Unlike standard limit switches which only indicate damper drive linkage position, the position switch is mounted directly on the main damper drive axle or on an auxiliary axle off of an indirectly driven blade. This assures true damper blade position indication. DESIGN FEATURES:
- Adjustable axle mounted collar provides for easy set-up and adjustment minimizing labour costs.
- Electrical enclosure has a 1/2" knockout which allows for quick and easy installation.
- Dual, opposed switches in the same enclosure provide for indication of fully open or closed.
- Switches can be set by user as NC or NO (form A or B)
- Fits 1/2” shaft only SWITCH RATINGS:
- 4A at 125 VAC LOOP POWERED INDICATOR LPI-1 - 4-20mA DESCRIPTION: LPI-1 loop powered indicators with large 3-1/2 digit LCD are designed to display any 4 to 20mA signal directly in the engineering units of the measured media. The display is powered directly by the measured 4 to 20mA signal so there is no need for a power supply. APPLICATIONS:
- Temperature indication
- Pressure indication
- Kilowatt demand
- Voltage indication
- Humidity indication
- Differential or static pressure
- Gallons per minute /f_low
- Current indication
- Other 4 - 20mA indications SPECIFICATIONS: Supply voltage • Powered by milliamp control loop Input • 4 - 20mA dc Impedance • 300 ohms nominal Accuracy • ±0.1% of scale Adjustments • SP AN (GAIN) and ZERO (OFFSET) Decimal point • 3 positions or none (user selectable) Range • -1999 to +1999 Operating temp. • 0˚C to 50˚C (32˚F to 122˚F) Humidity • 95% Non-condensing Connection • 2 pin screw terminal Cutout required • 25.1 mm (0.988") x 55.5 mm (2.19") Panel clearance • 40 mm (1.6") Display • 3-1/2 digit Digits size • 11.43 mm (0.45") LCD Dimensions • 35.5 mm (1.4") H x 58.67 mm (2.31") W FEATURES:
- Snap in panel mounting
- Large easy to read LCD display
- Optional NEMA 4X enclosure
- Pre-calibrated for desired range (optional)
- Optional selector switch for multiple indicators on one display unit NOTE: Impedance is rated at 24 VDC and 20mA. Exercise caution to avoid too much impedance in the current loop. Most transmitters are rated 500 to 750 ohms. ORDERING: DES-100 - Provides two output signals to indicate a fully open and fully closed position. DES-101 - Provides two output signals that act as a double pole switch.
