The SNAP-HD-G4F6 header cable has two uses: to connect a 32-channel digital module to older G4 digital I/O racks, and to connect a 32-channel digital output module to two SNAP-TEX-MR10-16C breakout boards in order to switch multiple loads up to 10 amps.
Connecting to G4 Digital I/O
The SNAP-HD-G4F6 header cable connects a SNAP 32-channel digital input module (
SNAP-IDC-32) or output module (
SNAP-ODC-32-SNK) to two G4 digital I/O racks. This allows older G4 (or even G1) digital output systems to be integrated with modern Opto 22 products like SNAP PAC controllers, SNAP Ethernet-based brains, and PAC Project software. This connection makes available the G4 output module's 3 amp switching capability, providing 12 times the 0.25 amp capability per point of the high-density digital modules.
The SNAP-HD-G4F6 connects one of the specified high-density digital modules with two G4PB16H, G4PB16HC, PB16H, or PB16HC racks. All G4 or G1 modules on the rack must be of the same type (input or output) and of the same logic voltage (5, 15 or 24 VDC). For a SNAP-IDC-32, logic voltage must be 15 or 24 volts, not 5 volts.
Note that the SNAP-IDC-32 returns positive-true logic, which is the inverse of the typical negative-true logic most modules return.
This cable cannot be used with a SNAP-ODC-32-SRC module when connecting to G4 racks.

To connect the SNAP-IDC-32N module to G4 or G1 racks, see the
SNAP-HD-G4F6N电缆。
Connecting a 32-channel Output Module in order to Switch Loads to 10 A
The SNAP-HD-G4F6 header cable can also be used as a quick method to connect a 32-channel
SNAP-ODC-32-SRCdigital output module to two
SNAP-TEX-MR10-16Cbreakout boards, each of which has 16 mechanical relays that can switch loads up to 10 amps.
使用此电缆的优点是，您不必将模块连接到突破板上。只需将电缆捕捉到模块的顶部，然后将电缆的另一端插入两个突破板上的标题连接器。
