| In
cash register systems and certain robot and PLC systems,
20 mA current loops are common. With the MA-21, which
converts between a 20 mA current loop and RS-232/V.24,
point to point connections as well as loops can be used.
The interface can handle up to six units. The equipment
can be switched to active/passive for current source.
MA-29 and MD-21 are alternative products. |
