2 Hardware
The ME-63Xtend series consists of external extension boards
for DIN rail mounting. The series includes the following models:
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:

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. Other-
wise 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. 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:

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 indu-
ced 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 dis-
charge 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 provi-
ded for every contact switching a considerable load.

2.2 ME-632
The ME-632 is an external extension board with 16 opto-isola-
ted 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. Depen-
ding on the I/O-board further signals are feed-through to the 25-
pin 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 invol-
ved 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 correspon-
ding 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 con-
nect 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!
Diagram 6: Jumper ME-632
If required, alternatively the positive references (JP17a, JP18a,
JP19a) or the ground references (JP17b, JP18b, JP19b) of adjacent
groups can be connected with each another.

2.3 ME-633
The ME-633 is an external extension board with 16 opto-isola-
ted digital output channels. The outputs are designed as open
collector outputs and can switch up to 60V (specifications see
page 41). For each channel the positive and negative output is
connected with the clamp. The 4 channels of a clamp are com-
bined in a group. For status control one LED per channel is as-
sembled before the opto-isolation. Depending on the I/O-board
further signals are feed-through to the 25-pin D-Sub female con-
nector ST2 (see table 7).

2.3.2 Jumper Settings
By jumper a common reference can be made between the invol-
ved channels of a group (see diagram 9).
For the output channels a common ground can be defined for
each group. For every channel, which should be refered to it, the
corresponding jumper JPxmust be set. By the clamps KLx.1 the
ground reference for each group must be done. For example: if
the jumpers JP1 and JP4 are set you can connect the ground re-
ference of group KL1 to the clamp KL1.1.
Diagram 9: Jumper ME-633
If required, the grounds of adjacent groups (JP17a, JP18a, JP19a)
can be connected with each another. Additionally the positive re-
ferences between the groups KL2 and KL3 (JP18a) can be con-
nected.

2.3.3 Pullup Resistors
As pullup resistors RUP (see diagram 9) resistor arrays with 4 se-
parate resistors come with the package.
If you want to use pullup resistors a positive reference for the
groups KL1 and KL2 must be done by clamp KL1.10. For the
groups KL3 and KL4 a positive reference must be done by clamp
KL3.10. If necessary you can you use different resistor values for
each channel.
