DNx-DIO-452, DNA-DIO-452, DNR-DIO-452, DNF-DIO-452

The DNx-DIO-452 are 12-channel, electromechanical relay board. The DIO-452 boards are designed for use in a wide variety of switching and digital control applications. Each channel is configured as a standard Form C (SPDT) relay and switches voltages up to 220 VDC or 250 VAC.

Each channel is rated for continuous operation at 2 Amps @ 30 VDC and 0.75 Amp at 125 VAC with an output voltage of less than 200 mV (<200 mOhm).

All relays default to "NC" on power up/reset. Switching rates up to 125 Hz are supported. There are no fuses or overcurrent protection devices on the board. If an overcurrent condition is possible, we recommend the use of an external fuse.

All connections are made through a convenient 37-pin D connector ensuring no problems obtaining mating cables or connectors. Users may also connect the DNx-DIO-452 boards to our popular DNA-STP-37 screw terminal panel via the DNA-CBL-37S cables. The cables are fully shielded and are available in 1, 3, 10 and 20 foot lengths.
