Product catalog summary

Overview: The C-mac® Voltage Relay RV20 is a DC voltage monitoring relay designed for monitoring DC input signals. It features adjustable setpoints and hysteresis, with selectable activation or release of the relay. It supports both DC and AC supplies up to 230 VAC and offers 1- or 2-pole relay outputs.

Specifications:

Supply Voltage: AC options include 24, 115, and 230 VAC ±10%; DC options include 24 VDC ±10%.
Supply Frequency: 40-70 Hz.
Variable Supply: 12-50 VDC or 48-250 VDC.
Isolation Voltage: 3.75 kV between supply, input, and output.
Power Consumption: 2.5 VA.
Operating Temperature: -20°C to +60°C.
Humidity: 0-90% RH, non-condensing.

Functional Features:

Relay Inversion: Configurable via pin 6-7 for undervoltage or overvoltage release.
Adjustments: Setpoint and hysteresis adjustable via potentiometers (5-100% for level, 5-50% for hysteresis).
Indications: Green LED for supply voltage connection, Red LED for relay activation.

Performance:

Accuracy: 5% scale.
Temperature Coefficient: Typically 0.1% per °C.
Max Load: 1-pole relay supports 8 A at 250 VAC; 2-pole relay supports 5 A at 250 VAC (ohmic load).
