Increase the capacity of your 34980A data acquisition system (195-3167) with this terminal block from Keysight Technologies. It's a multitasker that's equipped with 64 independent relay channels. This means that it controls multiple components like sensors, indicator lights and solenoids simultaneously, improving automated operation. The device handles up to 60W of input power without a hitch, so it's a dependable choice for heavy-duty applications. It has an integrated temperature sensor to help prevent overheating, so it doesn't lose its cool in demanding conditions.

• Low channel-to-channel capacitance of 20pF for high-integrity signal transmission
• Standard 78-pin D-sub connector ports for compatibility with many cables and interconnect solutions
• Quick open and close time of 4ms for rapid-fire results
• Relay lifespan of 100,000 cycles at rated load for long-lasting performance

• Robotics and automation
• Process and packaging industry
• Oil and gas plants

The Keysight 34939A is a high density general-purpose switch module for the 34980A Multifunction Switch/Measure Unit. It has 64 independent single-pole, single-throw (SPST) relays that can switch 1A and carry 2A. This module can be used to cycle power to products under test, control indicator and status lights, and to actuate external power relays and solenoids. The relays are 100V, 1A contacts and can handle up to 60W. Standard 78-pin Dsub connectors allow for use with standard cables, screw terminal blocks, or mass interconnect solutions.
