1 General Specifications GS48C7BEN B Analog Input Module (open < 3.8 ma) GENERAL Figure This Analog Input module, or amplifier, contains two circuits and can be utilized for various applications. The open line detection level is configured for 3.8 ma. B Analog Input Module (open < 3.8 ma) This module has a number of typical characteristics: Galvanic isolation between inputs and between inputs and logic Supply for passive transmitters Current or input Internal or external set point setting with set point limiter LED indication Transmitter and set point outputs Open line input detection Normal or inverting operation Shift register circuit for connection to the Sequence of Event Recording system (SER) The incoming field current signal is converted to a signal. This signal (or a input signal) is internally compared with the set point and open line levels. The result of comparison with the set point is used for the circuit output. Depending on the wiring, the output is a high or a low signal. The result of the open line comparison can be used to disable the output in case of a line fault. Open line levels are set by resistors on the module. Both set point and field input signals are available for monitoring as a V signal. Yokogawa Europe Solutions B.V.
