  • Page 13: Chapter 1. General Information

    Figure 1-1 shows a typical layout for each of the relay multiplexers. Each multiplexer consists of a component assembly and a terminal module. The Agilent E1345A, E1347A, E1355A, and E1356A multiplexers use the same component assembly, but each multiplexer uses a unique terminal module.

  • Page 14: Safety Considerations

    Safety Considerations These products are Safety Class I instruments provided with a protective earth terminal when installed in the mainframe. Check the mainframe, multiplexer, and all related documentation for safety markings and instructions before operation or service. Refer to the WARNINGS on page 4 in this manual for a summary of safety information.

    E1347A, E1355A, and E1356A modules. The maximum voltage that may be applied between High (H), Low (L), and Guard (G) terminals is 250VDC or ACrms (354Vpeak) for the E1343A or E1344A. The maximum current is 50 mA (non-conductive) per channel. The maximum power per channel is 1 VA.

  • Page 16: Relay Life

    Relay Life Electromagnetic relays are subject to normal wear-out. Relay life depends on several factors. Two factors are loading and switching frequency effects. Loading and Relay Load. In general, higher power switching reduces relay life. In addition, capacitive/inductive loads and high inrush currents (e.g., when Switching turning on a lamp or motor) reduce relay life.

    250VDC or VACrms. The E1344A provides Descriptions a thermistor reference junction on the terminal card for thermocouple measurements. Both modules use the E1343A relay component module but they have different terminal card assemblies. E1345A/47A The E1345A and E1347A multiplexers provide multiplexing for up to 16 channels (channels 00 through 15).
