Solid State DIDO Modules
The DO functionality of the modules utilize either a 120 VAC / 2 amp, a 240 VAC / 1 amp, or a
60 VDC, 3 amp solid state relay. A five-position screw down connector serves as the gateway
between the Relay Module peripheral controller and the external mechanism. The DI portion
of the module is an input-sensing device. Utilizing opto-isolation circuitry the module accepts
make/break contacts used as monitoring devices or as input status messages.
Figure 2-16
provides a wiring diagram for the 120 and 240 VAC versions of the module:

FORM-C DIDO Modules
The DO functionality of the Form “C” Relay Module utilizes an AC (Alternating Current) up to
two hundred forty (240) volt, one ampere, Form “C” relay or up to a 24 VDC / 2 amp, Form
“C” relay. The DI portion of the module is an input-sensing device. Utilizing opto-isolation
circuitry, the module accepts externally generated signal levels such as make/break contacts
used as monitoring devices or as input status messages.
Figure 2-18 provides a wiring diagram
for the Form-C modules (shown wired for Normally Open operation):
