MM4380A DC INPUT, FIELD RANGEABLE ISOLATED TRANSMITTER FEATURES · Allows Inputs to ±256 V or · Fully Labeled Jumper Positions ±100 mA for Easy Range Settings · 15 mV or 0.8 mA Minimum Input · Provides a Fully Isolated DC Span Output Proportional to DC Input ® · Size, Pinouts and Performance · Choice of Power Options SOME MODELS Identical to MM4300 & MM4300A · Permanent Warranty · User-Settable Input and Output Ranges DESCRIPTION interchangeable with fixed-range TYPICAL APPLICATIONS Eliminates ground loops and common The MM4380A provides a DC output modules such as the MM4300 and MM4300A. mode signals. Use for voltage/current proportional to a DC input. The output is fully isolated from input, line power and All Wilkerson products are designed with scaling and conversion with isolation for ground. The unit is useful in eliminating RFI filters and lightning protection to buffering and noise reduction. Single- ground loops and common mode reduce susceptibility to electrical noise unit replacement module provides field rangeability for all normal input and signals. and damage by lightning. It utilizes a feedback VCO to develop a pulse train output ranges. Input and output ranges are user- settable. Each may be voltage or current, with a duty cycle proportional to the input with or without offset. The output signal amplitude. This pulse train is response may be normal or reverse- coupled through a pulse transformer to acting. A fully-labeled set of jumpers the output circuitry, where the duty cycle data is converted to a proportional DC selects the input and output ranges. The MM4380A is identical in size and fully output level. SPECIFICATIONS OUTPUT LOAD LINEARITY Voltage ±0.05% of span INPUT RANGE 10 mA max.
