RDL ST-LCR3 Logic Controlled Relay - Dual Alternate PulseThe ST LCR3 is ideally suited to applications where momentary pulses are needed from a single control signal. The module provides a momentary pulse when a logic signal at its input first becomes active. A separate momentary pulse is provided when the logic signal at the module input becomes inactive. Two logic inputs are available on the ST LCR3. Either of these inputs may be used. Terminal 1 is internally pulled high to +5 Vdc. This input becomes
