Telecom Relays Dealers in Bangalore

Features Programmable for 1A / 5A relay rating Programmable system rated frequency (50/60Hz) 3 OC + 1 EF + 1 SEF/REF Available in both Low load and normal load configurations Choice of 6 IDMT curves and definite time Trip test facility History of 6 latest faults along with settings Self supervision facility MODBUS open protocol over RS – 485 port MODBUS protocol over RS – 232 port Draw out facility with inbuilt CT shorting Standard dimension – 144mm x 144mm Principle of Operation: The relay measures the line current from each of the line CTs and if the current exceeds the set threshold, then relay extends a trip signal after an operating time. The relay's “operating time” is determined by selecting “definite time” or one of the six “inverse time” characteristics. Input to sensitive earth fault protection can be derived in two ways: Residual current derived from three phase current transformers can be used as an input Out put of core balance current transformer (CBCT) having appropriate characteristics can be used as an input. Input to high impedance restricted earth fault protection will be derived from neutral CT output with external stabilizing resistor. Phase over current, Earth fault, Sensitive earth fault/Restricted earth fault protections features can be made active or inhibit independently. Inhibition of all protection is not possible

Telecom relays, A relay is an electrically operated switch. Many relays use an electromagnet to mechanically operate a switch, but other operating principles are also used, such as solid-state relays. Relays are used where it is necessary to control a circuit by a separate low-power signal, or where several circuits must be controlled by one signal. • SIGNAL RELAY • GENERAL POWER RELAY • AUTOMOTIVE RELAY • MAGNETIC LATCHING RELAYE

• Color: Black or Customized
• Voltage (V): 110, 220, 380, 500
• Size (mm): 20.2*10.0*11.5, 10.6*5.7*9

Telecom Relays are also known as Signal Relays are relatively small and designed to switch signal-level loads in communications systems, test gear, thermostats, instrumentation, consumer electronics and industrial equipment. These relays typically have relatively low operate and release times compared to other general purpose relays. Most are sealed, and some offer surface mount terminals
