Interface plug-in power relays consume less power
A new range of interface plug-in power relays for panel board and mechanical engineering applications is being launched by Tyco Electronics as an extension to the successful Schrack RT family of relays. The new XT series plug-in relays are available as one-pole (1 CO contact, 16A rated current) and two-pole (2 CO contacts, 8A rated current) versions. A very low coil power of only 400mW for the DC coil version and 750mVA for the AC coil version make XT relays the most power-saving plug-in relays in their class, according to Tyco.
Using reinforced pins for plug-in and panel applications, the XT series relays do not require special sockets, and the 5mm pinout for both versions reduces logistical cost by using the same socket. A smoked clear cover allows easy visibility of the contacts. A mechanical indicator is fitted as standard to show the contact position, and there is a lockable manual test facility. Visual indication can be provided by an integrated LED and an optional internal protection diode (with DC coil types).
The RoHS-compliant XT series plug-in relays additionally benefit from reinforced insulation, enabling them to meet protection class II (VDE 0700) specifications. Further technical details include a maximum switching capacity of 4000VA/2000VA (1-pole/2-pole version), and an operating temperature range of -40 up to +70 degrees Celsius. DC and AC coil versions are colour-coded, thereby minimising the risk of incorrect usage.
