DELCON
SLI input relay for mA loads
The relays are used as an interface between AC sensors and control systems. The integrated interference protection provides reliable operation even in very demanding electrical environments. Thanks to interference protection, signal cables can be run alongside power cables on, for example, cable racks for more than 1.5 km without capacitive cross-talk affecting relays. The relays have no mechanical parts, which provides very reliable application. The CRP models are especially designed for connecting to 2-wire sensors that generate leakage current. The CRP relays are blind to leakage currents up to 3.5 mA.

Ambient temperature is defined as the temperature in direct proximity to the relays. | ||
Ambient temperature | Applies to | Limitations |
-25°C to +40°C | All input relays | None |
+40°C to +55°C | 120 V ac and 230 V ac relays | Only every other module should be constantly activated when the relays are mounted beside one another |
+55°C to +70°C | Relays with voltages from 48-230 V ac | If the modules are in the activated state the majority of the time, the modules must be 12.5 mm apart. On a mounting base, every other position must be empty |
- AC control / DC load
- Galvanic isloation 4kV, 8mm creep distance
- Effective interference elimination
- Compatible with both NPN and PNP logic
