24-Pin Mass Termination Block

The 24-pin mass termination block can be used with 4-wire Analog Input 4-20 mA and 1-5 VDC applications that are conducted over 0.093 mm2 (28 AWG) ribbon cable with 2x12 header connectors (AMP part # 1658622-3, Strain Relief # 1-499252-0) or round instrument cable.

The Phoenix Contact 2301134 FLK16/24DV-AI/EZ-DR/100 24-pin to 16-pin conversion cable can be used with 4-wire applications. The conversion cable uses the Phoenix Contact 2304432 FLKM16 VARIOFACE ribbon connector module and comes in one meter (three foot) and other lengths. The Phoenix Contact 2304432 FLKM16 VARIOFACE ribbon connector module is an Emerson Alliance Program product.

CAUTION!

When using a 24-pin ribbon cable, there must be a slight fold in the cable at the cover opening. Damage might occur if the cable is pinched by the cover.
