3.2 Product Descriptions
The I/O modules plug into the ROC364 I/O module rack sockets and accommodate a wide range of
process inputs and outputs. The I/O module rack provides sockets for up to 16 I/O modules. Up to 64
I/O modules can be used in any combination of Discrete Inputs, Discrete Outputs, Analog Inputs,
Analog Outputs, and Pulse Inputs. A minimum of one rack is required for any ROC connected to field
I/O, and a maximum of four racks can be accommodated. The first rack plugs directly into the I/O
module rack connector on the bottom edge of the MCU. Additional racks plug into each other.
The following modules are available:
♦
Analog Input (AI) Loop
♦
Discrete Output (DO) Relay
♦
Analog Input (AI) Differential

Interface
Below each I/O module socket is a plug-in terminal block for field wiring connections. The plug-in
terminal blocks permit removal and replacement of the modules without the need to disconnect field
wiring. I/O wiring terminal blocks accept up to 12-gauge American Wire Gauge (AWG) solid or
stranded copper wire. Figure 3-1 shows a typical I/O module.
NOTE:
Use a standard screwdriver with a slotted (flat bladed) 1/8-inch width tip when wiring all
terminal blocks.
