Description
The 778572-66 and 778573-66 are part numbers referring to a specific 2 A, 16-Channel, SPDT PXI Relay Module. This module features SPDT Form C armature relays, known for their non-latching operation. An important aspect of these modules is their low thermal offsets and extremely low on-resistance, which are crucial for applications requiring precise control and minimal power loss.
The module’s topology can be configured as either 16-SPDT or 8-DPDT, giving users flexibility in how they set up their signal routing. It supports a max switching voltage of up to 150 V DC and 125 V AC between channels, and the same values apply for the channel-to-ground voltage, classified under CAT I standards. This module is also designed to handle impulse voltage tolerance up to 800 V, ensuring robust performance under transient conditions.
When it comes to power, the module can manage a max switching power of 60 W or 62.5 VA (DC to 60 Hz) and a max switching current of 2 A for both DC and AC signals. The relay’s operate time is impressively quick, with a typical speed of 2 ms and a maximum of 4.4 ms, allowing for a max cycle speed of 115 cycles/s.
This module is designed for efficiency and compactness, with a 3U, one-slot PXI form factor and a weight of just 250 g (9 oz). Its dimensions are 8.5 x 0.8 x 5.1 inches, making it a space-saving option for tight setups. Connections are made via a male, 62-pin D-SUB I/O connector. Power consumption is modest, requiring only 4.5 W at 5 V, which helps to maintain low operational costs and heat
