Yokogawa 100% Brand New Analog Output Module ALR121-S00

The Yokogawa ALR121-S00 is a serial communication module designed for use in field control stations (FCS) to facilitate communication with subsystems such as the FA-M3. Let’s delve into the technical specifications of this module:

1. Interface:

• ALR111: RS-232C

• ALR121: RS-422/RS-485

2. Connection Method:

• ALR111: Point-to-point

• ALR121: Point-to-point (RS-422) or multipoint (RS-485)

3. Communication Function:

• Half-duplex

4. Synchronization Method:

• Start-stop synchronization

5. Transmission Speed (bps):

• 1200/2400/4800/9600/19200/38400 (Note: The applicable speed depends on the communication function, subsystems, and connection method.)

6. Transmission Code:

• ASCII/binary

7. Character Length:

• 7/8 bits

8. Stop Bit Length:

• 1/2 bits

9. Parity Check:

• None/even/odd

10. Lag Time After Data Transmission:

• 1 ms (The time to start receiving data again after data transmission.)

11. Transmission Distance:

• Maximum 15 m (for RS-232C)

• Maximum 1200 m (total extended length, for RS-422/RS-485)

12. Installation Method:

• Mounted on ANB10, ANB11, ANR10, AFF50, AFV10, AFV30, or AFV40

13. I/O Wiring:

• Use AKB131, AKB132, AKB133, AKB134 cables or cable with 3-pair shield (AKB161 or AKB162)

• Wiring connection via D-sub-9-pin (female x 2) or clamped with terminal block’s M4 screws (5 poles x 2)

14. Current Consumption:

• 0.5A

15. Weight:

• 0.3 kg
