Overview

This two-channel interface supplies light to two fiber optic sensors, monitors the amount of light transmitted through the sensors and detects small changes caused by loads applied to the sensors.  With its advanced circuitry, the interface can detect a load on a sensor for as long as it is applied to the sensor. The MD-220 incorporates a TI MSP-430 embedded microcontroller, programmable via a JTAG interface. It has a 10-wire screw-clip interface with power supply terminals and four floating optocoupler outputs. It also has a RS-232 interface data transmission and troubleshooting. Direct external control is possible through the use of an 8- way SIL switch, two jumpers and a reset switch. For quicker troubleshooting, six LED status displays show the function of the interface and there are five easily accessible test points for analog measurements. Power consumption has been minimized by circuitry that operates the transmitter diodes in series while independently controlling the current through each diode. The MD-220 uses near infrared diodes which give each channel a dynamic range of 30 dB.
