ELECTRICAL CONNECTIONS

3.6.2 2005A SSR Output (DOM)

Recommended connections to a customer relay are shown in Figure 3-10. Make SSR
output connections as shown in Figure 3-11. Note: (*) indicates module may be operated
at 2 amps only if there is no module on either side of this module.

DC output modules are used for controlling or switching DC loads. 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 DC output modules
include switching the following loads: DC relays, DC Solenoids, DC motor starters, or DC
lamps or indicators. Wire rating: 600 V, -20°C +105°C UL, CSA approved.
Module Fuse rating: 4 Amps, 250V.

AC output modules are used for controlling or switching AC loads. 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 AC output modules
include switching the following loads: relays, solenoids and contactors, motor starters,
heaters, lamps, or indicators. Wire rating: 600 V, -20°C +105°C UL, CSA approved.
Module Fuse rating: 4 Amps, 250V.
