The 831C-4 MOD is a compact DIL reed relay designed for reliable low-current switching in PCB-mounted electronic applications. Featuring a 12VDC coil, Form 1C (SPDT) contact configuration, and an integrated suppression diode, it provides stable and protected switching performance for precision electronic circuits.
Detailed Description
This relay is built for applications requiring compact size, fast switching, and improved circuit protection. The integrated diode across the coil suppresses back EMF (voltage spikes) generated during de-energization, helping protect driving components and improving overall system reliability.
Its DIL (Dual In-Line) package allows straightforward PCB integration and compatibility with standard board layouts used in industrial electronics, instrumentation, and automation systems.
With reed contact technology, the relay delivers fast response time, low contact resistance, and long operational life. It supports a maximum switching current of 250mA and an electrical rating of 250mA at 100VDC, making it ideal for low-power signal and control applications.
The compact 20 × 8 × 6mm form factor makes it suitable for space-constrained designs, while the 500V isolation voltage ensures safe and stable operation in sensitive environments.
