Specifications
I/O Indicator
Indicates the ON or OFF status of input from the B7A Link Terminal or the ON and OFF status of output to the B7A
Link Terminal.
ERR Indicator
Incorporated by the B7AI1 and lit when the B7AI1's data transmission or reception is abnormal.
Connection Terminals
SIG: Connects to the SIG terminal of the B7A Link Terminal.
V–: Connects to the negative power terminal of the B7A Link Terminal.
! Caution If the terminals are not connected correctly, the internal circuitry of the B7A Link Terminal will be
damaged.
Note 1. The transmission cable must be a VCTF cable with a thickness of 0.75 mm
2. Do not wire power lines or high-tension lines along with the transmission cable in the same conduit.
Input Mode Selector
The B7AI1 incorporates an input mode selector on the back panel of the Unit, with which the following modes can
be set.

Status of the ERR indicator
The ERR indicator is lit when an error occurs. If the error is corrected, the ERR indicator is OFF at the next trans-
mission cycle.
When there is a transmission error, the B7A Link Terminal will hold the data just before the occurrence of the trans-
mission error. If there is a transmission error because the B7A Link Terminal is turned off, however, data 0 is trans-
mitted in the first transmission cycle when the B7A Link Terminal is turned on again.
Transmission errors between the C200H-B7AO1 and B7A Link Terminal are detected by the B7A Link Terminal
only. Check the ERR indicator and error bit for any error.

Weight
Note 1. The minimum input time refers to the minimum time required for reading the input signals from the CPU
Unit. The ON/OFF width of the signal transmitted from the CPU Unit to the Output Relay of the B7A Inter-
face Unit should be set to a value larger than the minimum input time.
2. The value of the external power supply does not include the value required by the B7A Link Terminal.
