Multiplex Transmission System

MULTI-TRANSMISSION MODULE

Functions & Features

[2] POWER INPUT

AC Power

• Miniaturized, plug-in, socket-mounted version of the

multiplex transmission system

K: 85 – 132 V AC

• Analog, digital or pulse string signals transmitting via

twisted-pair cable

(Operational voltage range 85 – 132 V, 47 – 66 Hz)

L: 170 – 264 V AC

• No master station required

(Operational voltage range 170 – 264 V, 47 – 66 Hz)

DC Power

• Easy expansion up to 256 modules (2000 points)

S: 12 V DC

Typical Applications

(Operational voltage range 12 V ±10 %, ripple 10 %p-p max.)

R: 24 V DC

• Input and output processing for computer systems and

telemetering systems

(Operational voltage range 24 V ±10 %, ripple 10 %p-p max.)

• Complete system compatibility with DLA1 and other units,

utilizing the same communication protocol

GENERAL SPECIFICATIONS

(2.83)

Connection

Power input: M3.5 screw terminals

PWR

RUN

(3.15)

Field I/O: M3.5 screw terminals or 26-pin connector

Transmission: Euro type connector terminal

Housing material: Flame-resistant resin (black)

Isolation: I/O to transmission to reset (provided only for

pulse I/O type) to power

PU-2

(5.67)

mm (inch)

Terminator: Incorporated (remove jumper pin with those

modules not located at the end of transmission line)

Power indicator: Red LED turns ON in normal conditions;

OFF when the voltage level becomes low.

RUN indicator: Red LED turns ON when the selfdiagnosis

proves normal, OFF in an abnormality.

■ RUN Output: Contact opens when the self-diagnosis

detects an abnormality.

MODEL: 22LA1–3[1]–[2]

G3: Ai 8 points

Memory: Sum check

Power voltage: Detects when the voltage supply to the CPU

drops.

COMMUNICATION

Communication: 2-wire, half-duplex

G4: Ai 4 points

M3: Ao 8 points

Transmission: conform to RS-422, EIA
