The Series SI Signal Simulators are a range of multi-channel Digital and Analog Input/ Output signal generating instruments, which can be used to generate or interrogate Digital and Analog signals in the ranges specified. This range of microcontroller based instruments are designed using state of the art techniques in signal generation and conditioning, thus providing accurate and reliable signal and sensor sources. The instruments find applications in plant commissioning, testing and fault finding and instrument calibration. 

Offered in several executions like hand-held, free-standing, panel and field-mounted versions, these instruments provide accurate representation of signals calibrated from certified and traceable sources. 

The Series SI Signal Simulators are designed for continuous full load operation in tough industrial environments. Additional features such as a Digital indication of Voltage, Current and other parameters, easy signal selection and settings are also provided for ease of operation. The instruments are also customized to user specifications. 

All ASHE instruments carry a lifetime warranty against defects in components and workmanship.
