Product Details

Phoenix Contact PLC-RSC Series

PLC Interface single- and double-pole relays, and opto-couplers, having the same profile. This allows the modules to be installed in any configuration with a common bridging system and using the same accessories. The V8 adapter connects 8 relays or opto-couplers to a 15 way D-SUB cable.

Features and Benefits

• Relays and opto-couplers for inputs and outputs with "pluggable" switching devices
• Four bridging slots to reduce wiring; bridging of up to 80 modules is possible
• Screw terminal connections
• LED indicators and diodes for coil suppression
• 250V versions have a switched power rating of 1500VA
• Mechanical life (relays) 1 x 107 operations
• Wide range of accessories also available

REL-MR- 24DC/21

The REL-MR-24DC/21 SPDT (Single pole, double throw), plug-in miniature power relay has an input voltage of 24 Vdc and power contact. The non-latching relay is part of the REL-MR range and has been designed to be assembled in rows with zero spacing.

Features and Benefits

• Up to RT III protection meaning that the relay is capable of undergoing a washing process to remove any flush residue without leakage of flux or washing product.
• Operating temperature of -40°C to +85°C
• Silver Alloy contact material
• Safe isolation between coil and contact according to DIN EN 50178
• Power contacts up to 6 A

Typical Applications

The SPDT relay is a commonly used when there is a need to select between two power sources, swapping inputs or where you need two circuits going to one place.


When using this type of relay is sometimes vented to the atmosphere after the soldering or watering process. In this case the requirement with respect to clearance and creepage distance can change.
