The 16-pin mass termination block provides 1:1 signal transmission of eight signals to the external passive input/output modules. The two-row header accepts a 16-pin 1-for-1 passthrough, 0.093 mm2 (28 AWG) ribbon cable with 2x8 header connectors (AMP part #1658622-3, Strain Relief #499252-8). The assembly interfaces to an IDC-to-discrete-wire module, such as the Phoenix Contact 2304432 FLKM16 VARIOFACE ribbon connector module, or other similar modules. The Phoenix Contact 2304432 FLKM16 VARIOFACE ribbon connector module is an Emerson Alliance Program product.
