TELEMECANIQUE CA2DK22P5

Telemecanique CA2-DK Latching Control Relay

Description

The Telemecanique CA2DK22P5 is a high-reliability latching control relay designed for industrial control applications. As a bistable relay, it maintains its last switched position without continuous power to the coil, making it highly energy-efficient and ideal for circuits where state memory is critical during power outages. This unit features a 2NO and 2NC contact arrangement and is operated by a 230V 50Hz AC coil.

FAQ

Question?
What is the primary difference between this CA2DK22P5 latching relay and a standard control relay?

Answer: The CA2DK22P5 is a latching relay, which means it mechanically holds its last position (energized or de-energized) even after the control power is removed. It requires a separate electrical impulse to change state, making it ideal for applications where power conservation or state memory during power loss is critical. A standard relay returns to its default state when the coil is de-energized.

Question?
How is the latching and unlatching function controlled on this relay?

Answer: This relay uses two separate control inputs. One electrical pulse to the ‘set’ terminals (e.g., E1/E2) closes the NO contacts and opens the NC contacts, and the relay remains in this state. A subsequent pulse to the ‘reset’ terminals (e.g., A1/A2) will return it to its original state.

Question?
Is the 230V 50Hz coil interchangeable with other voltages?

Answer: No, the coil is specific to the model number suffix ‘P5’, which designates a 230V 50Hz AC coil. Attempting to use a different voltage can damage the coil or cause unreliable operation. If a different control voltage is needed, a relay with the corresponding coil code must be used.
