PHOENIX CONTACT PLC-BSC-12DC/21 2966896 / 2961150

Phoenix Contact 12V DC DIN-Rail Relay ModuleDescriptionThis is a PLC-INTERFACE module from Phoenix Contact, combining the PLC-BSC-12DC/21 basic terminal block with a plug-in miniature relay (REL-MR-12DC/21). This compact unit is ideal for galvanic isolation and signal amplification in industrial control cabinets. Its slim 6.2 mm design allows for space-saving installation on a standard DIN rail.SpecificationsManufacturer: Phoenix ContactBase Model (Socket): PLC-BSC-12DC/21Relay Model (Plug-in): REL-MR-12DC/21Nominal Input Voltage: 12V DCContact Type: 1 N/O (Normally Open)Maximum Switching Voltage: 250V AC/DCLimiting Continuous Current: 6 AConnection Method: Screw connectionMounting Type: DIN rail: NS 35/7,5Label InfoBase Order Number: 29 66 896Relay Order Number: 2961150ApplicationDesigned for universal use in automation, machine building, and process control.

If the relay fails, you can quickly replace just the plug-in component (REL-MR-12DC/21) without having to unwire the entire base from the DIN rail, minimizing downtime.Question?Is this module suitable for switching inductive loads like small motors or solenoids?Yes, the AgSnO (Silver Tin Oxide) contacts are designed for good performance with both resistive and moderately inductive loads. However, for highly inductive loads, it’s always recommended to use an additional protective circuit like a freewheeling diode or RC snubber to protect the contacts and extend their lifespan.Question?Can I use a different 12V DC relay in this PLC-BSC-12DC/21 base?It is strongly recommended to only use the specified Phoenix Contact REL-MR series relays. While other relays might physically fit, using a non-specified relay can lead to improper connection, overheating, or failure, and would void any certifications or warranties.profideals is not an authorized distributor, reseller, or representative of the products featured on this website.
