MODULAR I/O CONNECTIONS
4.3.2 2004A SSR Input (DIM)
Make Solid-State Relay (SSR) connections as shown in Figure 4-3. 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
WARNING
All wiring connected to the controller terminals must be rated for the
maximum voltage present, or alternately, wiring in circuits operating at
greater than 30 volts must be rated for at least twice the circuit voltage.
