Overview and Applications

many helpful features such as DAQ Assistant, automatic code

generation, and high-performance multithreaded streaming technology.

The National Instruments 6521 products are industrial digital I/O devices

with eight channel-to-channel isolated digital inputs and eight nonlatching

mechanical relay outputs. You can use the eight differential, isolated,

±30 VDC digital inputs to read the status of sensors, actuators, and logic

devices. You can use the bipolar digital input channels to read from both

sinking and sourcing devices. NI 6521 devices register a logic low if the

voltage is between ±± V, and register a logic high if the voltage is less

than -11 V or greater than +11 V.

Safety

• UL listed: UL 61010-1 (IEC 61010-1)

• Keyed connector

• Insulation covers

• Complete software configuration

• High-voltage accessories

NI 6521 devices are UL listed and require the use of a keyed connector

to prevent high-voltage signals from accidentally being connected to a

low-voltage device. For added safety, PCI-6521 includes insulation covers

on both sides of the board to prevent the user from coming in contact

with high-voltage traces. Complete software configuration means that

the user at no point is required to come in the vicinity of high-voltage

traces. Several low-cost, high-voltage accessory options are available

to ensure safe operation.

NI 6521 devices offer three single-pole double-throw (SPDT) Form C

relays and five single-pole single-throw (SPST) Form A relays. You can

use NI 6521 relay outputs to switch devices requiring up to 150 V AC/DC.

NI 6521 relay outputs have maximum current rating of 2A and maximum

switching power of 60 W.

Note: The switching current is limited by the maximum switching

power and maximum voltage. (current = power/voltage)

NI 6521 devices offer completely programmable configuration and do not

require setting up jumpers or DIP switches. These devices are ideal for use

with a programmable automation controller (PAC) for automotive test,

industrial monitoring, and control applications. With high-current drive, high-

voltage outputs, and isolation, you can connect the digital I/O module directly

to a wide array of industrial electronic devices, sensors, and actuators.

NI 6521 devices take advantage of NI-DAQmx measurement services

software (Version 7.5 or later) to speed up application development with
