New Original Omron G3PC-220B-VD Solid State Relay
1. Product Overview
The Omron G3PC-220B-VD is a slim DIN rail mounted solid state relay (SSR) belonging to Omron’s G3PC compact series, brand new and original factory stock. It features DC control input and AC resistive load output with a rated load current of 20A and zero-cross switching circuit. The control side accepts wide-range 4–32 VDC driving signals, which can be directly driven by PLC transistor outputs, photoelectric sensors, temperature controllers and other DC control units. An integrated aluminum heat sink is embedded inside the thin plastic housing to deliver continuous heat dissipation during full-load operation. Built-in protective circuits include overheat shutdown, reverse input polarity protection and RC surge absorption to avoid component damage caused by miswiring, overload and inductive load surges. Unlike traditional mechanical relays, this contactless SSR eliminates contact bounce, electric arc and mechanical wear, supporting long-term high-frequency switching. It is widely deployed in heating control systems, packaging machinery, conveyor equipment, industrial oven power regulation and automation cabinet power switching applications.
2. Main Functions
- Contactless AC load switching: Realize on/off control of AC circuits without mechanical contacts to extend service life and reduce electromagnetic interference.
- Zero-cross turn-on switching: Conduct switching action at the zero point of AC voltage waveform to suppress inrush current of resistive loads such as heating tubes.
- Wide DC signal driving: Compatible with 4 VDC to 32 VDC input signals to match most mainstream industrial DC control devices.
- Automatic overheat protection: Cut off output load once internal temperature exceeds safety threshold to prevent permanent burnout.
- Reverse polarity protection for control input: Prevent circuit breakdown when the positive and negative control wires are connected in reverse.
- Visible operation indication: Equipped with a red LED light to display the energized status of the control input for easy on-site inspection.
- Dual installation compatibility: Supports standard 35 mm DIN rail snap mounting and direct screw fixing on metal mounting plates.
- Built-in RC surge absorption circuit: Suppress voltage spikes generated by inductive loads to stabilize overall circuit operation.
3. Core Technical Features
- Ultra-slim integrated structure, occupying less space inside compact electrical control cabinets.
- Embedded aluminum alloy heat sink structure with excellent continuous full-load heat dissipation capacity.
- No mechanical moving parts, capable of millions of stable high-speed switching cycles without performance attenuation.
- High dielectric isolation of 2500 VAC between control input and load output to ensure electrical safety.
- Flame-retardant PBT plastic housing, resistant to high temperature, aging and dust in harsh workshop environments.
- Compact terminal layout with clear printed marking for quick wiring and routine maintenance.
- Anti-vibration and anti-shock mechanical design, adaptable to equipment with frequent mechanical vibration.
- Low input power consumption, only small driving current required to control high-current AC loads.
- Stable operating performance within a wide ambient temperature range from low temperature to high temperature.
- Integrated anti-interference circuit to resist disturbance from surrounding power equipment.
