RL2 - 2 Channel Relay Output Module Quick Links

The AI2, a two channel isolated analog input module, is used for standard 10 V, 20 mA process inputs. It is commonly used for reading industrial process variables, for example, temperature or pressure.

Note - The relay is shown de-energized.
Key Description
1 External power supply 5 to 125 Vdc or 24 to 250 Vac
2 These outputs may require external snubber circuits to be fitted for suppression of transient voltages (depending on application). A resistor and capacitor (RC) snubber (22 nF 100 Ω in series) assembly can be ordered, see Ordering Contact Details with your EPM Solution. Alternatively, Metal oxide varistor (MOV) for ac loads and Diode/MOV for dc loads can be used if appropriate for your application.
