The SR2B121FU module from Schneider Electric is a smart relay that features a compact design optimized for efficiency in control systems. It accommodates a broad input voltage range from 85 to 264 VAC and operates efficiently at supply frequencies of 50 or 60 Hz. This relay module's maximum supply current is rated at 30 mA when using a 240 V supply, while it can manage up to 80 mA at a 100 V supply without requiring extensions.
Within this smart relay, there are eight digital input points, each drawing a current of 0.6 mA. The inputs are designed to function effectively within frequency ranges of 47 to 53 Hz or 57 to 63 Hz, allowing for flexible application in different environments.
The SR2B121FU module also includes four relay outputs, which can operate with an output voltage ranging from 5 to 30 VDC for direct current applications, or from 24 to 250 VAC for alternating current setups. The relay outputs are capable of handling an output thermal current of up to 8 A across all four outputs, providing robust control in automation tasks.
Weighing 0.25 kg (approximately 0.55 lbs.), this relay module is lightweight and ideal for applications that require compact solutions without compromising functionality. The SR2B121FU is engineered to deliver reliable performance in various industrial settings.
