Distributed Data Acquisition Modules 4DIN 8AI 4DO model

Model:DAM124   4DIN+8AI+4DO  Module

The DAM120 is for monitoring 4digital input(can be used as pulse counter), controlling 8 relay output(can be TTL or Pulse output). It supports Modbus RTU Protocol over RS485 serial port. Powered up by 10~30VDC.

The DAM120 is used widely in industrial automation control systems. E.g.: Base Transceiver Station, diesel generator rooms, engine room, transformer substations, telecommunication equipment rooms, power supply systems and so on.

The DAM120 is an industrial class, isolated designed, high reliability, low-power consumption, high stability and high precision data acquisition module.

The DAM120 with fire retardant shell, standard 35mm DIN rail makes it easy to install in fields.

Mainly Features:

•  4 digital input, Dry contact or Wet contact(logic:0~0.5V or NC=0, +3~30V or NO=1, input voltage range: 0~30V, Input Max. voltage range: -10~40V), can be used as pulse counter input: counter sampling frequency:1KHz, impulse width of high or low level must >1mS, Max. counter value is 4 bytes: FFFFFFFFH;
•  8 relay output(Rated 250VAC@3A or 30VDC@3A ), can be setup as TTL output or Pulse output(impulse width 0.1~20S);
• Wide range power supply with reverse polarity connection protection;
•  Modbus RTU Protocol;
•   ESD Protection circuit for RS485 serial port;
•   Using industrial-grade chips;
•   Built-in watchdog ensure it reliability;
•  Lightning protection ensure it stability;
•  LEDs for status indication makes it easy to program in filed.
