Static In-Line Timer
Solid state, in-line timing unit for AC or DC contactor and relay control circuits where a
timed “ON” delay is required. Typical application is on crane and mill drives. The tim-
ing range is field adjustable by integral potentiometer and ranges from 0.08 seconds to
16.0 seconds, depending on model.
Standard features include:
• Totally encapsulated, solid state design.
• Shock a vibration resistant.
• Wide range ambient temperature operation.
Electronic Frequency Relay
Master/slave system designed to be used with wound rotor motor controls. Master
unit, which can be used as a stand-alone relay, is a complete frequency relay provid-
ing one point of frequency detection. The slave unit must be used with the master
unit and provides additional point of frequency detection. Up to five slave units can
be used with each master.
Standard features include:
• Green “Relay-on” and red “Relay Picked-up” indicators.
• 5.5–218 hz response range.
• Single frequency adjustment set point for each device.
• Hand held calibration module to monitor, calibrate or troubleshoot the system.

Arc Suppressor
Designed to reduce contact arcing in DC control circuits with operating voltages
between 24 and 275 volts DC. When permanently connected in parallel with the oper-
ating coil, the arc suppressor may eliminate the use of an interposing relay.
Standard features include:
• Totally encapsulated, electronic design.
• Shock and vibration resistant.
• Operating voltage 24 to 275 volts DC.
• Operating temperature range from -40º to 65ºC.
Electronic Overload Relay
Performs both the inverse time and instantaneous trip functions normally
performed by two separate electro-mechanical overload relays. It receives
the current signals from an optional ammeter shunt and may be used with
any dc motor that requires overload current protection.
Standard features include:
• Automatic reset. Manual reset of trip indicators.
• Green “Overload-on” and yellow “Overload-Condition” indicators.
• Negative or positive shunt applications.
• Mill-duty design.
• Double break contacts.
• Latched red “Overload-Trip” indicators.
Lifting Magnet Controls
Varistor or resistor type, automatic discharge or manual, EUCLID has them.
Discharge resistor and varistor types provide safe discharge path for stored
energy. EUCLID
