2.1 Fitting
• Switch off terminal, disconnect power plug.
• Unscrew 3 screws on underside of cover at the front, lift off cover and place face down in
front of terminal.
• Undo ring nut of the interface socket.
• Lead interface socket outward, screw on ring nut from the outside and tighten. Ensure
correct seating of the rubber ring seal.
• Fit mounting clips on the 194-ISA interface (1).
• Insert 194-ISA interface into the weighing interface (2).

2.2.1 Connecting METTLER TOLEDO
GD14 Relay Interface
• Make sure that the following jumpers are
connected on the ST4 (factory setting):
1-3, 2-4, and 7-9.
The GD14 relay interface is attached to the
19 pole output plug (see Chapter 3).
2.2.2 Attaching to control circuit
(e. g. SPC)
The external supply voltage must be fed
through the GD14 connection cable or a
connection cable prepared by the user (see
Chapter 3) to the 19 pole output socket
(V+, V–).

1. Introduction
Interface 194-ISA is an I/O interface for the METTLER TOLEDO ID20/ID20-... Weighing
Terminals. The I/O ports are used for the open-loop and/or closed-loop control of signal
transfer with external devices (e. g. SPC, METTLER TOLEDO GD14 Relay Interface).
The interface 194-ISA has an output section with 8 relay circuits for the activation of control
circuits and an input section with 6 matching circuits for the receipt of signals.
