ME-631
The
ME-631
is an external
relay board with 16 change-over
relays
(form C). The relays can switch up to 30 VDC/6 A or
240 VAC/6 A (specifications see page 37). To drive the relays a
buffer circuit is inserted. For status control one LED per channel
is assembled. It is connected in parallel to the relay coil. Depen-
ding on the I/O-board further signals are feed-through to the 25-
pin D-Sub female connector ST2 (see table 3).
For relay control the following assignment is valid:
