Description
Instantaneous relay with rapid memory.
Pluggable on socket with a withdrawal clasp and square guide pins which can act as a key to ensure that the correct relay is used at the correct voltage (see our withdrawal guide in the technical support pages of this site)
Pluggable on the following sockets : EVB2/CA, ERC2/CA or ERDL2/CA.
Dimensions
Operation principle
This relay is a rapid memory which acts when it receives an impulse with duration > 0.5 ms (terminal 14). This information is re-sent (tipping of the two CO contacts) when validated by action on terminal 13 (validation). This information is directly re-sent il terminals 13 and 15 are linked. Return to rest state is made by cutting-off terminal 15 (reset).
See the operation diagram hereafter
