MSK = Input circuit
(terminal allocation according to type, see Figs. 8 to 13)
A1
= Measuring output
A12
= 2nd. measuring output (field indicator) voltage drop across field indicator or milliammeter ≤ 300 mv,
resp. connection for hand held terminal
AF
= Output contact for monitoring the input circuit (fault signalling output)
Refer to the figure "relay" for details
