Before procurement teams confirm H3RN-21-B-DC24, they typically review Omron SMPS 24V 10A, Omron H3Cr A8 Ac100 240 Dc100 125 and Autonics Timers to double-check performance ratings, stock availability, and supplier credibility carefully.
Omron H3RN-21-B DC24 Timer
The Omron H3RN-21-B DC24 Timer provides dependable timing performance with a rated power supply voltage of 24 VDC and an allowable voltage variable range of 85 to 110% of the power supply voltage. It supports a reset voltage of up to 10% max. of rated supply voltage and offers 4 time ranges suitable for standard timing applications. The timer features an DPST-NO time-limit control output and connects through a 8-pin round socket (Push-In Plus Terminal Block). Manufactured by Omron, listed under Omron Timers, and part of the H3RN Series.
