4 Channel PLC Signal Booster Board For 3.3 To 24V DC IO Logic Level Converter NPN PNP Optocoupler Isolated MOSFET Module For DIN Rail Mount 5A Drive 2000 Hz Switching Easy Install

4-Channel PLC Signal Booster Board: 4/8/12/16 channels
✔️ 4/8/12/16 channels, DIN rail mount, 3.3-24V input, 2kHz

The 4-channel signal amplifier module shifts and isolates PLC IO signals, letting 3.3-8V and 8-24V control lines drive MOSFETs, relays, or optocouplers cleanly. Ideal for DIN-rail mounted control panels in industrial automation and machine automation.

✅ Control voltage: 3.3-8V and 8-24V
✅ Input current: 8-15 mA per channel
✅ Output drive: MOSFET/PNP-NPN compatible
✅ Switching frequency: up to 2000 Hz
✅ Isolation: optocoupler isolation for noise immunity
✅ Mounting: standard DIN rail mounting for easy panel install
✅ Indicator LEDs: per-channel current state indicators

💡 What is a PLC signal booster board used for in industrial automation?
