Description
HC4E-HTM-AC240V is a general-purpose PCB relay designed for high-reliability switching applications, featuring a 240VAC coil and multiple configuration options. It is suitable for industrial control, automation systems, and consumer electronics where robust isolation and switching capability are required.
Features
- Coil voltage: 240VAC
- Available in standard, amber sealed, and latching (keep) types
- Optional configurations with LED indicator, diode, and CR suppression circuit
- Multiple mounting types: PCB mount, plug-in, and terminal (TM) type
- High insulation and dielectric strength
- Compatible sockets and terminal bases available
Functional Description
- Electromechanical relay that uses an AC coil to actuate contacts
- Provides galvanic isolation between control and load circuits
- Supports switching of AC or DC loads depending on contact rating
- Variants with indicators and suppression components simplify system design
Design Notes
- Ensure proper coil drive voltage (AC 240V) with tolerance consideration
- Use snubber circuits (RC or MOV) when switching inductive loads
- Allow sufficient PCB creepage/clearance for high-voltage operation
- Consider sealed type for harsh environments (dust, humidity)
- Verify inrush current capability for loads like motors or lamps
How to Choose This Relay
- Select based on coil voltage (AC vs DC) and control system compatibility
- Verify contact rating vs load type (resistive, inductive, capacitive)
- Choose sealed type for reliability in harsh environments
- Consider versions with built-in suppression for noise-sensitive designs
- Check mechanical footprint compatibility with PCB or socket
Typical Applications
- Factory automation and industrial control systems
- Power supply equipment and control panels
- Machine tools, welding equipment, and molding machines
- Office equipment and vending machines
- Telecommunication and disaster prevention systems
- Medical and measurement devices
- Household appliances and consumer electronics
