Catalog 1308242 Issued 3-03 P&B CS series Solid State Hybrid Voltage Sensor • Close differential • Choice of two types – Fixed pick-up and knob adjustable drop-out – Knob adjustable pick-up and drop-out • Internal 2 Form C (DPDT) output relay Fixed Pick-up and Adjustable Drop-out Adjustable Pick-up and Drop-out File E22575 File LR15734 Users should thoroughly review the technical data before selecting a product part number. It is recommended that user also seek out the pertinent approvals files of the agencies/laboratories and review them to ensure the product meets the requirements for a given application. Sensing Modes Engineering Data The CS can be used as an over or undervoltage sensor, depending upon whether the load is connected to the normally closed (NC) or normally open (NO) contacts of the sensor’s output relay. Power Requirement: Typically less than 3VA or 3W. Duty Cycle: Continuous. Repeatability: ± 1%, max. Response Time: 10-25 ms, typ. Internal Relay Contact Arrangement: 2 Form C (DPDT). Internal Relay Contact Rating: 10A @ 28VDC , res., or 120VAC, 80% p.f. Reverse Polarity Protection: On DC types. Temperature Range: -10°C to +55°C. Temperature Coefficient: 0.2%/°C, max. Enclosure: Plastic dust cover. Mounting: 8-pin octal style plug. Fits either 27E122 or 27E891 (snap-on) screw terminal sockets. Weight: 8 oz. (227g) approximately. Overvoltage sensor – The NC contacts are used. The relay remains deenergized until an overvoltage is sensed. Undervoltage sensor – The NO contacts are used. The relay remains energized until the voltage decreases to the preset level, where the sensor de-energizes the relay. Adjustable Voltage Sensor Operation Note 1 – As voltage increases, the relay will pick-up at its selected point and remain energized while voltage is maintained at that level or higher. VOLTAGE RELAY ENERGIZED Note 2 – As voltage decreases, after pick-up, the relay will drop-out at its selected point. HYSTERISIS 2 VOLTS RELAY DE-ENERGIZED NOTE 1 Ordering Information – Distributors are more likely to stock boldface items. Note 3 – Minimum hysterisis, the voltage differential between pick-up and drop-out, is typically 2% of pick-up. .560 (14.22) 2.406 MAX.
