On Delay Timers - Zelio RE17R Series RE17R series timing relays enable simple automation cycles to be set up using wired logic. They can also be used to complement the functions of PLCs. Relay outputs provide complete isolation between the supply circuit and the output. It is possible to have several output circuits. On-delay function Multivoltage LED state indicator Relay output, C/O contact, 8A Screw terminals DIN rail mounting Note Off-delay function available in RS 791-2723
