Interfaces and Connectors
All interfaces signals except the serial. Communication interfaces are discrete 24 VDC
logic signals.
Output signals (OUT) are sourcing transistor outputs. Input signals (IN) are transistor
inputs.
Max current of each signal is given in the tables below. Total current (sum) must,
however, be within instrument specification.
