SERIES GP SERIES TR GP/ML/TR Design Features Features Among the advances AGASTAT control relays offer over existing designs is Occupies very small panel space a unique contact operating mechanism. An articulated arm assembly May be mounted singly, in continuous rows or in groups. amplifies the movement of the solenoid core, allowing the use of a short Available with screw terminal molded socket. stroke coil to produce an extremely wide contact gap. The long support 4 SPDT contacts. arms used in conventional relays are eliminated. Both current capacity and Magnetic blowout device option increases DC current carrying ability shock/vibration tolerance are greatly increased, as well as life expectancy. approximately ten times for both N.O. and N.C. contacts. In both AC and DC operation, the addition of the device will normally double the contact life, due to reduced arcing. Design/Construction AGASTAT control relays are operated by a moving core electromagnet GP/ML Contact Data 25C whose main gap is at the center of the coil. A shoe is fitted to the core which overlaps the yoke and further increases the magnetic attraction. Arrangements: 4 Form C (4PDT) The coil itself is in the form of an elongated cylinder, which provides a Material: Siver plated. low mean turn length and also assists heat dissipation.

Voltage (Amps) Time Constant Operations Remarks Two of these mechanisms are placed side-by-side to actuate the four 540 VAC 3 COS = 0.5 15,000 2 contacts in series contacts sets of the relay. The outer arms of the W mechanisms are leaf 380 VAC 15 Resistive 10,000 2 contacts in parallel springs, manufactured from a flat piece of non-ferrous metal. These outer arms act as return springs for their corresponding contacts.

The current peak on energizing is also eliminated and consequently the relay 48 VDC 10 Resistive 1,000,000 can operate with a resistance in series (e.g. for high voltages or for drop- out by shorting the coil). The use of the rectification circuit offers still Load Life Curve other advantages. The same model can operated at frequencies ranging from 40 to 400 cycles. Operation of the relay is crisp even with a low AC voltage, there is a complete absence of hum and vibration. The plastic dust cover has two windows through which the iron yoke protrudes to facilitate cooling and also to allow direct mounting arrangement of the relay irrespective of the terminals.
