About This Product

■Summary

・Contact transmission device with 16 input/output points ・Communication speed 2,400bps (300bps switchable) ・As a successor model of MTR-J-N, pin assignment is common - Significantly improved environmental resistance and communication reliability ・Added function to maintain output even if the other party goes down

■Features

This device is a transmitting/receiving device for transmitting contact signals at up to 16 points using a dedicated line. There are two types of output signals: relay output type (MTR-J2-Ur) and transistor output type (MTR-J2-Ut), which can be used depending on the purpose.

■Operating principle

On the transmitting side, a microcomputer converts the 16 parallel signals received from the input connector into serial signals, and a modem IC applies frequency modulation to the voice band frequency carrier and sends it out to lines L1 and L2. On the receiving side, the modulated waves sent from lines L1 and L2 are demodulated by a modem IC, converted to a parallel signal by a microcomputer, and output as a signal to the output connector via the output circuit. The modem IC has a full duplex function, so the above transmission and reception can be performed in both directions at the same time. There are two operating modes: origin mode and answer mode, and they must be used in pairs. The operating mode can be easily changed using the DIP switch on the front.
