National Instruments 778572-66 SPDT Relay Module.
The part number 778572-66 from National Instruments is the identifying part number for the PXI-2566 SPDT Relay Module. This module can be configured as 16 SPDT relays or 8 DPDT relays. The switching voltage between channel to channel is rated at 150 Volts DC or 125 Volts AC. The maximum switching current per channel is 2 Amperes. At maximum current, this module can operate 16 channels simultaneously. The carry current this module offers per channel is 5 Amperes, with around 9 channels working simultaneously.
The relays take 2 ms to switch from one state to the other and can take a maximum of 4.4 ms with a maximum cycling speed of 115 cycles per second. This module has a mechanical life of 1 × 108 cycles and an electrical life of 5 × 105 cycles when being used at 30 Volts DC while drawing 1 Ampere or 3 × 105 cycles when operating at 125 Volts AC, drawing 0.2 Amperes. This module has 8 memory addressable trigger lines which allow it to control the switching of the channels accordingly. The minimum pulse width required for the signal to act as a control signal is 150 ns.
The 778572-66 SPDT Relay Module has electromechanical non-latching relays allowing them to stay in the Normally Closed position when no power is applied to the module or when the control signal state is not active. The Gold-clad silver alloy relay contacts keep the contacts protected from corrosion and high temperatures due to high amperage. The connector required to transmit and control the relays is the 62-pin D-SUB male connector. This particular module requires 4.5 Watts of power at 5 Volts or 2.5 Watts of power at 3.3 Volts to operate.
The 778572-66 SPDT Relay Module has dimensions of 21.6 × 2.0 × 13.0 cm (8.5 × 0.8 × 5.1 in.) and weighs 250 grams. It should be operated in an environment with temperatures less than 55 degrees Celsius and humidity between 5% to 85%, noncondensing. With this module has a pollution degree level of 2.
