ELECTRICAL CONNECTIONS

3.5.2 2004A SSR Input (DIM)

Make Solid-State Relay (SSR) connections as shown in Figure 3-4. These input modules

are used for sensing ON/OFF voltage levels. Each module provides optical isolation

between the field devices and the control logic. This isolation is limited to 250 Vrms at the

terminal block. Typical uses and applications for these input modules include sensing

voltage and contact conditions from: proximity switches, limit switches, selector switches,

push buttons, photoelectric switches, TTL compatible devices, float switches, or

thermostats.

Wire rating: 600 V, -20°C +105°C UL, CSA approved.
