SD indicator: Red LED turns on when transmitting.

RD indicator: Red LED turns on when receiving.

INPUT SPECIFICATIONS

■ Analog Input

Input range: 1 – 5 V DC

Input resistance: ≥ 1 MΩ

(Each input must be isolated by signal conditioners. Non-

isolated modules such as M2BW and M8BW are not usable.)

A/D conversion

Moving averaging: 4 samples

Sampling rate: 160 ms

A/D conversion output: Signed binary

Signal range 0 – 100 % is converted into hexadecimal 0000

– 2710 (0 – 10000). -15 to 0 % is a negative range

represented by 2's complements.

Overall range is represented by hexadecimal FA24 – 2CEC

(-1500 – +11500), for -15 – +115 %.

OUTPUT SPECIFICATIONS

■ Analog Output

Output range: 1 – 5 V DC

Load resistance: 20 kΩ minimum

(Output must be isolated with signal conditioners.

When the transmission line is open, the last value sampled

before failure is held. Non-isolated modules such as M2BW

and M8BW are not usable. )

D/A conversion input: Signed binary

Signal range 0 – 100 % is converted into hexadecimal

0000 – 2710 (0 – 10000).

-15 to 0 % is a negative range represented by 2's

complements.

Overall range is represented by hexadecimal FA24 – 2CEC

(-1500 – +11500), for -15 – +115 %.
