The 40-pin mass termination block provides terminations for the 32-channel digital input and output cards and the Sequence of Events card.
For Use with 32-Channel DO and DI Cards
The 40-pin mass termination block has two, 20-pin IDC headers that split the 32 channels into two, 16-channel headers. Both of the two-row headers accept a 20-pin 1-for-1 passthrough, 0.093 mm2 (28 AWG) ribbon cable with 2x10 header connectors (AMP part #1658622-4, Strain Relief #499252-2). The assembly interfaces to a feed-through IDC-to-discrete-wire module such as the Phoenix Contact 2281047 FLKM20 VARIOFACE ribbon connector module. The Phoenix Contact 2281047 FLKM20 VARIOFACE ribbon connector module is an Emerson Alliance Program product. Phoenix Contact provides two ways to connect to the 20-pin connection:
- A 20-pin to 2x14-pin configuration cable that connects to all 8-channel digital input and output modules. These modules include the PLC-RELAY with V-8 adapter, fuse, feed-through and relay (both solid-state (SSR) and electromechanical relays (EMR)).
- A 20-pin 1-for-1 cable that is connected to 16-channel modules. These modules include feed-through, fuse, relay, (SSR and EMR) and relay modules with fuses on the relay contact commons.
The 40-pin mass termination block can also interface to the DO and DI Mass Connection Solutions as well as to the Pepperl+Fuchs HiD Series Boards if IS Barriers are required. The Pepperl+Fuchs HiD Series Boards are Emerson Alliance Program products.
The return connection is made internally when the 40-pin mass termination block is used with Series 2 DI and DO 32-channel cards. No external wire is required. Refer to the cards’ installation notes for more information.
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.
For Use with SOE Cards
The 40-pin mass termination block has two, 20-pin IDC headers that split the 16 channels into two, 8-channel headers. Both of the two-row headers accept a 20-pin 1-for-1 passthrough, 0.093 mm2 (28 AWG) ribbon cable with 2x10 header connectors (AMP part #1658622-4, Strain Relief #499252-2). The assembly interfaces to a feed-through IDC-to-discrete-wire module such as the Phoenix Contact 2281047 FLKM20 VARIOFACE ribbon connector module. Phoenix Contact provides the following way to connect to the 20-pin connection:
