Keysight / Agilent / HP E1355A 8-Channel 120 Ohm Strain Relay Multiplexer

The Keysight E1355A is an 8-channel, 120 Ohm strain relay multiplexer module engineered for precision strain gauge measurements and general-purpose relay switching within VXIbus data acquisition systems. This register-based B-size, 1-slot VXI module delivers high-accuracy signal routing for test and measurement applications requiring multiple sensor inputs. ## Technical Specifications • Channels: 8 • Channel Impedance: 120 Ohms • Module Type: Register-based VXIbus • Form Factor: B-size, 1-slot • Interface: VXIbus standard ## Key Features • Dedicated 120 Ohm termination for strain gauge compatibility • Register-based control architecture for deterministic command execution • Single VXI slot occupancy minimizes chassis real estate requirements • Modular integration with existing VXI instrumentation systems • VXIplug&play driver support for automated configuration and control ## Typical Applications • Multi-channel strain and load cell measurements • Transducer signal conditioning and routing • Structural health monitoring data acquisition • Materials testing and stress analysis • Environmental test chamber instrumentation • Bridge circuit switching and multiplexing ## Compatibility & Integration The E1355A integrates directly into VXIbus mainframes and operates within modular test systems alongside compatible relay and multiplexer modules including the E1343A, E1344A, E1345A, E1347A, and E1356A. VXIplug&play drivers enable software control and automated system configuration. Service and user documentation remain available for legacy system support and maintenance. Product Status: Obsolete. No direct replacement identified by Keysight.
