Procurement managers rarely finalize H3CR-A8E-AC-DC24-48 without reviewing Omron SMPS 24V 10A, Omron H3Cr A8 Ac100 240 Dc100 125 and Autonics Timers, ensuring that the chosen component meets budget, compliance, and delivery conditions.
Omron H3CR-A8E AC/DC24-48 Timer
The Omron H3CR-A8E AC/DC24-48 Timer is designed for precise timing control with an allowable voltage variable range of 85% to 110% of rated voltage (90 to 110% at 12 to 48 VDC). The model supports a reset voltage within 10% max. of rated supply voltage and offers 18 time ranges for flexible operation. With a DPDT time-limit control output, 8-pin round socket connections. Manufactured by Omron, listed under Omron Timers, and part of the H3CR-A Series.
