Screw Terminals for AS-B Servers with 36 I/O Points

AS-B servers with 36 I/O points use nine pluggable terminal blocks and one fixed terminal block.

Recommended screw tightening torque: 0.56 Nm (5 lbf.in)

The terminal blocks are used as follows:

  • One 3-position pluggable terminal block for the power input

  • One 2-position fixed terminal block for the two return (RET) terminals 4 and 5

  • One 4-position pluggable terminal block for the RS-485 communication

  • One 6-position pluggable terminal block for the six universal inputs/outputs of type Ub

  • One 6-position pluggable terminal block for the four triac outputs

  • One 8-position pluggable terminal block for the four relay outputs

  • Four 6-position pluggable terminal blocks for the 20 universal inputs/outputs of type Ua

    One of the terminal blocks also accomodates two terminals for universal inputs/outputs of type Ub.

The screw terminals 6 to 9, intended for RS-485 communication, act as connectors to the AS-B server and are easily inserted/removed without disrupting the network. Doing so may help in isolating possible RS-485 communication problems.
