(2) Explanation on the External I/O Terminals
Terminal No.
Description
1
[24V-2 EXT]

If the MEA-100B is connected to a contact or NPN open collector
output-type device (when using the built-in power supply), connect
this terminal to terminal 2.

If the MEA-100B is connected to a NPN open collector output (when
using an external power supply) or PNP current output-type device,
connect this terminal to a 24 V DC external power supply.
2
[24V]
The output terminal for 24 V DC power generated in the MEA-100B .
Before shipment, this terminal is connected with a jumper wire to
terminal 1.
This power supply is for external input signals only. Do not use for any
other purpose.
3
[SOL COM]
*

Photo-MOS relay output: Common terminal of power supply for
solenoid. Outputs 24 V DC power.

Relay output: Common terminal of contact output for solenoid
4
[SOL1] *
Output terminal for Weld Force 1.

Photo-MOS relay output: 24 V DC, 0.1 A

Relay output: 24 V DC, or 250 V AC or less, 0.5 A
5
[SOL2] *
Output terminal for Weld Force 2.

Photo-MOS relay output: 24 V DC, 0.1A

Relay output: 24 V DC, or 250 V AC or less, 0.5 A
6
[EXT GND]
Terminal for EXT GND.
Connect this terminal to the shielded wire of the RS-485 signal cable.
7 [RS485+]
8 [RS485-]
Terminals for RS485+ and RS485-.
Connect this terminal to the RS-485 signal cable.
9
[COM] *
Common terminals when using the Photo-MOS relay output with the
external power supply.
10
[CAUTION]
*
Output terminal for [CAUTION] signal.
When a "caution" fault occurs, this circuit is closed.
(Preset the fault signal attribute so that the caution signal can be output
when the fault occurs. For details, see 9. (2)

.)
The circuit is opened when [ERR RESET] is closed.

Photo-MOS relay output: 24 V DC, 0.1 A
11
[STP/WELD
END] *
Output terminal for Step End [STP END] and Weld End [WELD END]
signals

The Stepper-up function is ON (SU:1)
Stepper-up end signal is output
The circuit is closed upon completion of the stepper-up operation.

The Stepper-up function is OFF (SU:0)
Welding end signal is output
The circuit is closed upon completion of welding within a welding
sequence.
Note: For timing details, see
11. Timing Chart
.

Photo-MOS relay output: 24 V DC, 0.1 A
12
[READY] *
Output terminal for [READY] signal.
The circuit is closed when the
MEA-100B
is ready for welding.
The READY signal is turned off until transmission of the confirmation
data is completed after data is received in the bi-directional
communication. (See 14. (7).)

Photo-MOS relay output: 24 V DC, 0.1 A
