CAD32 Contactor Relay (Control Relay) — Product ApplicationsProduct PositioningThe CAD32 is a contactor-type control relay (intermediate relay), an interface device designed for control circuits. It resembles a power contactor in appearance, but its contacts are rated only for low-current switching (conventional thermal current 10 A) and is intended for control circuits, not main power circuits.Core Applications

表格ApplicationDescriptionSignal amplification / contact expansionA low-level control signal energizes the coil (A1–A2), and the 5-contact arrangement (3 NO + 2 NC) simultaneously switches multiple independent circuits — "one input, multiple outputs."Control signal relay / bufferingSits between weak-signal sources (PLC outputs, pushbuttons, sensors) and actuators (contactors, solenoid valves, indicator lights), providing intermediate drive capacity.Electrical interlockingUses the 2 normally-closed (NC) contacts to implement mutual-exclusion logic — dual-pump selection, motor forward/reverse interlock, door interlock — ensuring one load is confirmed OFF before another can start.Change-over / switchover relayThe 3 NO + 2 NC combination forms a change-over circuit: when the coil energizes, it routes power to Load A while de-energizing Load B.Safety / pilot circuitsNC contacts are used in emergency shutdown and fault-detection loops, where signal continuity is maintained under normal conditions and broken on energization to trigger alarms or safe shutdown.Status indication & alarmingNO/NC contacts drive indicator lamps and buzzers to reflect running, stopped, or fault states.Typical Applications

Automated machinery — machine tools, packaging machines, production lines; signal relaying and interlocking in control cabinets.

HVAC systems — zone switching, dual-pump / dual-fan selection control.

Building automation — lighting control, elevator door interlock, fire-control signal relay.

Power distribution & protection — signal expansion and alarm loops in relay-protection circuits.

Industrial water pumping — duty/standby pump change-over, dry-run protection interlock.

Key Specifications

Contact configuration: 3 NO (normally open) + 2 NC (normally closed), 5 poles total

Rated operational voltage (Ue): ≤ 690 V AC

Conventional thermal current (Ith): 10 A

Mounting: 35 mm DIN rail snap-on / screw-on panel mounting

Terminal type: screw-clamp terminals

Coil terminals: A1, A2 (coil voltage varies by suffix, e.g., AC 220 V, DC 24 V)

In short: It is a signal transfer station in control circuits — one small input signal expands into multiple contact outputs for expansion, interlocking, and protection.
