■ Electric Heating Elements
— Instant indication of heater status.
■ Power Supplies
— Signals over-current before equipment fails.
■ Machine Operation
— Instant status of motors, lamps and other loads.
■ Telecom Sites
— Monitors battery output.
■Compact, One-piece Design
— Fits in easily amongst motor starters and power supplies in crowded control panels.
— Safer than shunt/relay combinations.
— Isolated output greatly simplifies wiring.
— Designed to handle harsh industrial environments.
— Hysteresis is 5% of setpoint, allowing closer control than fixed hysteresis switches.
— Solid state design.
■Built-in Mounting Feet
— Simple, two-screw installation allows for secure mounting.
