Figure 1 These five relay-driver circuits accommodate a variety of control signals and supply-voltage levels. One operates from CMOS-logic levels (a), and another operates from TTL levels (b). Another ...
This chapter covers representative general-purpose relays used in the control circuits of most industrial, commercial, and consumer products. This chapter covers representative general-purpose ...
Impulse relay turns on with an electrical impulse at the control input and turns off again with another impulse.
and other devices requiring safe operation by means of redundant circuits. The Machine Primary Control Elements (MPCE) 1 and 2 are typically a relay with force guided contacts. When a safety ...
