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.
Engineering Data
Sensing Modes
Pow er Requirem ent: Typically less than 3VA or 3W.
Duty Cycle: Continuous.
Repeatability: ±1% , max.
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.
Response Tim e: 10-25 ms, typ.
Internal Relay Contact Arrangem ent: 2 Form C (DPDT).
Internal Relay Contact Rating: 10A @ 28VDC , res., or 120VAC, 80% p.f.
Reverse Polarity Protection: On DC types.
Tem perature Range: -10°C to +55°C.
Tem perature Coefficient: 0.2% /°C, max.
Enclosure: Plastic dust cover.
Overvoltage sensor – The NC contacts are used. The relay remains de-
energized until an overvoltage is sensed.
Undervoltage sensor – The NO contacts are used. The relay remains en-
ergized until the voltage decreases to the preset level, where the sensor
de-energizes the relay.
Mounting: 8-pin octal style plug. Fits either 27E122 or 27E891 (snap-on)
screw terminal sockets.
Weight: 8 oz. (227g) approximately.

Ordering Inform ation –
Distributors are m ore likely to stock boldface item s.
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.
