16-Channel, 24 VDC Discrete Output MTA
Marshalled Termination Assemblies for ET200M Remote I/O Modules

A5E00482820-12
Field Terminals, C (
CHx+
), Channel – (
CHx-
), and Shield (
SHx
), connect
to the field devices.
CHx+
is connected to the output signal of each DO module
(Module 1 and Module 2). The necessary diode decoupling for the output signals is
realized onboard the Digital Output Module DO16xDC24V/0,5A and not on the
MTA.
CHx-
is the field device return.
Redundant operation uses two Digital Output Modules.
Connection from the MTA to the I/O Module is accomplished with a 40 pin Siemens
connector wired to a D25 male connector.
!
Caution
The heat sink can be over 100 °C. Avoid contact during servicing.

Installation Requirements
, before performing any installation and observe all
warnings
A common interconnecting cable (6ES7922-3BD00-0AT0 or 6ES7922-3BJ00-
0AT0), supporting 16-Channel Discrete outputs, interconnects the discrete output
termination assembly to the 16-channel, 24 VDC discrete output module (6ES7
322-8BH10-0AB0.
Note
To disconnect the interconnecting cable shield from ground at the MTA only, cut
and remove the shield disconnect jumper for the associated cable. See Figure
16.5
Maintenance
See Section 3,
, before performing any maintenance and observe all
warnings
Under normal operation, the
A/B
Power LEDs
and
the
Module 1 or 2 Fuse LEDs
are green illuminated. If an
A/B
Power LED
is red illuminated or off, check the
power supply to the MTA. If a
Module 1 or 2 Fuse LED
is off, check and replace
the module fuse.
