- Compact, One-piece Design - ..Fits in
easily amongst motor starters and power supplies in crowded control
panels.
- Input Isolation - Safer than shunt/relay
combinations.
- Output Installation - Isolated output
greatly simplifies wiring.
- Tough - Designed to handle harsh industrial
environments.
- Adaptive Hysteresis - Hysteresis is 5% of
setpoint, allowing closer control than fixed hysteresis switches.
- Built-in Mounting Feet - Simple, two-screw
installation allows for secure mounting.
