General Information

The Model 12584-001 I/O Control Module provides 32 dry contact inputs and 32 digital outputs. The
control module requires a 12 or 24 volt dc power supply. For communication and control by other
systems, the control module is equipped with two types of serial data interfaces (RS-232 and RS-485).

Data Connec tions

The I/O Control Module supports both RS485
and RS-232 data connections. A jumper is
provided to select either RS-485 or RS-232
data communi cations. The use of either the
RS-485 or RS-232 is dependent on the
application. Please refer to the
interconnecting device for data connection
details (i.e., AMI manua l).

For RS-485, the data connections are made
directly to TB2, terminals 1 and 2. Typically,
TB2-1 (+) and TB2-2 (-) connect to the
corresponding + and – terminals on the
controlling device.

For RS-232, a standard male DB-9 connector is provided. A null modem cable should be used when
connecting to the controlling device.

WARNING

TB10 and TB9 - Digital Output Connections

Do not apply power until all the connections have been wired.

Connect only to a U L-listed Class 2 power source.

The TB10 and TB9 connectors each provide 16 digital (common ground) output connections designed to
drive externally-mounted relays or other indicating circuits. Each output can sink up to 150 mA of the
current. External circuitry (relays, indicators, etc.) must be powered from an external power supply of the
same voltage used to power the I/O Control Module (12 to 24 V dc). The ground (or dc common)
terminals of the external power supply must be tied to TB4-2.

TB5, TB6, TB7, and T B8 - Digital I nput Conne ctions

The TB5, TB6, TB7 and TB8 connectors each provide connections for eight contact closure inputs.
Switches or relay contact closures are used to activate the inputs. The input contacts may be any
comb inati on of mo me ntary (pulsed) swit ches and ma intained (latch e d) switches . They can be e ither N .O.
or N.C. dry contacts rated at 5 mA minimum.

N

OTE: For the inputs to operate reliably, the cable loop resistance connecting the relay/switch contact

closures cannot exceed 200 ohms. For example, using 24 AWG cable, the maximum cable length for
connection of the relay/switch contact closures cannot exceed 1,500 feet. Refer to the terminal block
assignment charts and Figure 3 below.
