Comadan RV20 DC Voltage Sensing Relay – Low Voltage Input, 11 Pin

Description

DC voltage sensing relay for monitoring low-voltage DC signals. Trips the 2CO 5A@250VAC output contacts when the monitored DC voltage exceeds or falls below the adjustable setpoint. 230VAC auxiliary supply, 11 pin plug-in. Available in four input ranges from millivolts to 50VDC. Commonly used for battery voltage monitoring, DC process signal supervision, and shunt-based current measurement via voltage drop.

Note: Requires ZB11 11-pin relay base socket (sold separately). For DIN rail retention, add CMAC Spring Clip. For wider input ranges including AC, see the RV30.

Available input ranges:
– RV20-220V-60MV: 3-60mVDC input, 2CO 5A@250VAC, 230VAC aux
– RV20-230V-5V: 0.25-5VDC input, 2CO 5A@250VAC, 230VAC aux
