IDEC RH2B-ULDC12V Relay
The IDEC RH2B-ULDC12V is a heavy-duty, DPDT (2 Form C) midget power relay engineered for high-density control panels and HVACR diagnostic applications. Featuring a 12VDC coil with a nominal 160-ohm resistance, this compact power relay delivers a robust 10A switching capacity, making it a reliable choice for motor loads and solenoid valve sequencing. The integrated LED indicator provides immediate visual confirmation of coil energization, streamlining field troubleshooting and reducing downtime. Built with silver cadmium oxide (AgCdO) contacts, the RH2B-ULDC12V is designed to mitigate contact pitting and arcing, ensuring long-term electrical durability in industrial environments. This blade terminal relay is specifically designed for socket mounting, facilitating rapid hot-swapping in the field without disturbing fixed wiring. Compatible with standard DIN rail or surface-mount sockets, it fits seamlessly into existing midget relay footprints where space and amperage ratings are critical factors.
Key Benefits- 10-Amp Contact Rating: High switching capacity in a small-form factor for reliable control of fans, pumps, and HVAC components.
- LED Diagnostic Indicator: Transparent housing and internal LED allow for quick status checks without a multimeter.
- Advanced Contact Material: Silver cadmium oxide contacts provide superior resistance to welding and electrical wear.
- Plug-and-Play Compatibility: Standard 8-pin blade termination ensures a secure fit with the SH2B-05 socket and similar mounting hardware.
- Broad Operating Temperature: Stable performance from -30?C to +70?C, suitable for unconditioned mechanical rooms.
Is the IDEC RH2B-ULDC12V suitable for inductive loads?
Yes, the 10A rating and silver cadmium oxide contacts are specifically designed to handle the inrush and inductive kickback typical of small motors and solenoid coils in HVACR systems.
Will this relay work with a 24VAC control circuit?
No, this specific model features a 12VDC coil. Applying 24VAC will damage the coil and potentially the indicator circuit. Always verify your secondary control voltage before installation.
Does this model include a manual check button?
The UL-style RH2B includes the LED indicator but does not feature the manual test button. For manual override capabilities, you would typically look for the 'C' suffix in the IDEC RH series part number.
