The RS416 supports dual redundant power supplies – “Power Supply 1 (PS1)” and “Power Supply 2 (PS2)”. The connections for PS1, PS2 and the fail-safe relay are located on the terminal block as shown in Figure 6 and Figure 7.

The RS416 can be equipped with either a Philips Screw Terminal Block or a Phoenix Plug Terminal Block. The Philips Screw Terminal Block has Philips screws with a compression plate allowing either bare wire connections or crimped terminal lugs. We recommend the use of #6 size ring lugs to ensure secure, reliable connections under severe shock or vibration. Both terminal blocks have a safety cover which must be removed via two Phillips screws before connecting any wires. The safety cover must be re-attached after wiring to ensure personnel safety. Refer to Table 3 below for a description of each terminal as well as sections 4.2.1 through 4.2.3 for wiring examples.
