OVERVIEW
AIN24-2 Analog Input Module is a module which has 14-way K-type thermocouple sensor, 5-way resistance type sensor and 5-way (4-20)mA current type sensor. The sampling data are transmitted to the master controller via RS485 port.
PERFORMANCE AND CHARACTERISTICS
- With 32-bit ARM based SCM, high integration of hardware and more reliable;
- Must be used with master controller together;
- RS485 communication baud rate can be set as 9600bps or 19200bps via dial switch;
- Module address can be set as 1 or 2;
- Wide power supply range DC(8~35)V, suitable to different battery voltage environment;
- 35mm guide rail mounting type;
- Modular design, pluggable terminal, compact structure and easy installation.

SWITCH | The master controller can connect to two AIN24-2 modules at the same time. Address selection: It is module 1 when the switch 1 is connected to 12 while module 2 when connect to ON position. Baud rate selection: It is 9600bps when the switch 2 is connected to 12 while 19200bps when connect to ON position. | ||
| POWER | Power supply normal indicator; It is flashing when the communication is abnormal for over 10s. | ||
