Precision Relays: The Interface of Modern Automation
Relays are the vital interface between low-voltage logic (like PLCs or sensors) and high-voltage actions. In the demanding environment of Indian industries, reliability is paramount. A failed relay stops a machine.
Our best-selling control relays are chosen for their robust construction, capability to withstand wide voltage fluctuations in the coil circuit, and proven performance in high ambient temperature environments. From simple signal switching in a control panel to critical motor protection, these are the industry standards.
General Purpose 'Ice Cube' Plug-in Relays
The Panel Standard: Plug-and-Play Logic Switching
The ubiquitous “Ice Cube” relay is the most common component in any automation panel in India. Used for logic interlocking, signal isolation, and driving light loads, these relays feature a transparent housing that allows technicians to visually inspect the contacts and observe mechanical operation for easy troubleshooting.
We stock the highly popular 8-pin (DPDT) and 14-pin (4PDT) variants that fit into standard DIN-rail mounted sockets, allowing for rapid replacement without needing to unscrew any wiring.
Key Features & Specifications:
Visual Indication: Built-in LED indicates when the coil is energized, simplifying diagnostics.
High Contact Reliability: Silver alloy contacts ensure low contact resistance and long electrical life (typically >100,000 operations).
Coil Voltages: Available in the most demanded voltages for Indian panels: 24V DC, 110V AC, and 230V AC.
Plug-in Design: Reduces downtime during maintenance by allowing instant swapping of the relay module.
Thermal Overload Relays (Bimetallic OLR)
Phase-Sensitive Protection: Saving Motors from Single-Phasing
In a country heavily reliant on induction motors for pumps, fans, and compressors, the Thermal Overload Relay is critical insurance. It protects motors from burning out due to over-current conditions caused by mechanical jamming or low voltage.
Crucially, our best-selling models feature Differential Phase Loss Sensitivity. In India, “single-phasing” (loss of one phase in a 3-phase supply) is a common cause of motor failure. These OLRs detect this condition and trip rapidly before the motor overheats and destroys its windings.
Key Features & Specifications:
Adjustable Current Setting: A dial allows precise setting of the motor’s Full Load Current (FLC).
Phase Loss Protection: Trips faster in case of single-phasing conditions, saving the motor.
Reset Options: Selectable Manual or Auto-reset modes to suit the application.
Trip Class 10: Standard tripping characteristic suitable for most industrial applications.
