Agilent / HP 44724A

The 44724A consists of a digital output component module and a terminal module. Each channel acts as an ON-OFF switch to control low-voltage DC devices (up to 55 VDC) or to drive logic levels (such as TTL or CMOS). An external power supply is required for DC devices and for logic devices. In addition, a pull-up resistor is required for logic devices. Since channel states can be programatically switched, the digital output can be used to switch devices on or off at rates up to 1 kHz.

• Maximum input voltage:
  
  
  
  • 55 Vdc between high and low terminal of each channel
    
  • 350 Vpeak or 250 Vdc between channels or between any terminal and chassis
  
  
• Maximum sink current: 500 mA DC per channel
  
• Off state leakage current: 0.25 mA @ 55 Vdc
  
• Fuse protection: 1A on terminal module
  
• Maximum reverse polarity current: 500 mA DC per channel
  
• TTL compatibility: 200 mA per channel with Vout ¡Ü0.4 Vdc
  
• On state resistance: <1.5 ohm
  
• Maximum switching rate: 1 kHz
  
• Maximum wire size: 16 AWG
