The opto-isolated I/Os of the models ME-632, ME-633 and
ME-634 are isolated up to 2500 VAC
eff
.
The ME-63Xtend series can be connected with many multi-I/O
and digital-I/O boards using appropriate connection cables. The
I/O-board requires at least two 8-bit TTL input resp. output ports.
For the following boards preconfigured cables are available:
ME-1000
ME-1400(A/B)
ME-630 series
ME-4600 series
ME-6000 series
Note: A detailed description of the connection options can be found in chapter
2.6 on page 30. Many other multi-I/O and digital-I/O boards with appropriate
TTL ports can be connected by special cables!
Special cable ME AK-D78/1000
(ME-1000 can not be combined with the ME-634!)
1:1 connection cable e.g. ME AK-D78(/1)
Special cable ME AK-D2578/4000 via additional mounting bracket for bi-directional ports (ME-630 USB:
direct connection to the 25pin D-Sub jack of the device)

Rev. 1.2E Manual ME-63Xtend Series
Attention : Make sure that no contact with voltage carrying parts
can happen by the wiring of the board. The external connections
to the board should only be made or removed in a powered
down state.
Look for proper connection of the cable. It must join the Sub-D
jack completly and must be fixed with the both screws. Otherwise a proper operation of the board can not be guaranteed!

2.1 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. Depending on the I/O-board further signals are feed-through to the 25pin D-Sub female connector ST2 (see table 3).
For relay control the following assignment is valid:

2.1.2 Protection Circuit
On the ME-631 electro-mechanical power relays are used. They
can switch currents up to 6 A. During switching the relays induced voltages and high transient currents occur. Therefore the use
of a protection circuit for the contacts is urgently needed. To
guarantee the efficiency of the protection circuit the distance
should not exceed more than 20 cm.
The following diagram shows a typical circuitry that could be
used. The values of the components used depend on the load
and the relay properties. The condensator C suppresses the discharge when contact opens and the resistor R limits the current
when switching the next time. The circuitry can be used for DC
and AC operation. The ME-631 offers a make contact as well as
a break contact. Therefore the protection circuit must be provided for every contact switching a considerable load.

2.2 ME-632
The ME-632 is an external extension board with 16 opto-isolated digital input channels. The voltage high-level can be in the
range of 2.5…60V (specifications see page 39). For each channel
the positive and negative input is connected with the clamp. The
4 channels of a clamp are combined in a group. For status control
one LED per channel is assembled after the input buffer. Depending on the I/O-board further signals are feed-through to the 25pin D-Sub female connector ST2 (see table 5).
For the inputs the following assignment is valid:

2.2.2 Jumper Settings
By jumper a common reference can be made between the involved channels of a group (see diagram 6).
The input channels can be refered alternatively to a positive
reference voltage or to a common ground. For every channel,
which should be refered to a positive reference, the corresponding jumper JPxa must be set. For every channel, which should
be refered to ground, the corresponding jumper JPxb must be set.
For example: if the jumpers JP1a and JP3a are set you can connect the positive reference of group KL1 to the clamps KL1.1 or
KL1.5.
Please note, out of each pair of jumpers only one jumper (e. g.
JP1a, JP1b) may be set!
