Table 5 - Port Location for Compatible Option Modules

See the SMC-50 user manual for a list of compatible 20-COMM-X modules.

When installed in an SMC-50 controller, 20-COMM-X modules physically reside in the space assigned to Port 9,

but connect to DPI Port 4 with the ribbon cable that is supplied with the communication module.

Optional Cat. No. 150-SM4 Digital I/O Module

A Cat. No. 150-SM4 Digital I/O Option Module provides four 120...240V AC
digital on/off inputs and three relay outputs to provide additional auxiliary
control or indications (e.g., up-to-speed (UTS), alarm, etc.) functions. The
150-SM4 module can be located in any of the three control module option ports
(See

Figure 12

). Up to three 150-SM4 modules can be used with a single control

module. The 150-SM4 module terminal block used to wire the I/O is removable.
