Analog Input 4-20 mA Signal Conditioning Card for 1771 I/O

Installation notes

The Analog Input 4-20 mA Signal Conditioning Card for 1771 I/O provides an interface between 1771 I/O and simplex or redundant Series 2 Plus 16-channel AI cards.
The swing-arm attachment point on the front of the card provides secure mechanical and electrical connections for a 1771-WG/WH swing arm.
The two 24-pin ribbon-cable connectors on the bottom of the card provide connections for a Simplex or Redundant Analog Input 48-Pin Plus Mass Termination Block, which is required to connect to a simplex or redundant Series 2 Plus 16-channel AI card.
Up to 16 analog 4-20 mA non-HART field devices can be connected to the swing-arm screw terminals.
You can connect 2- and 4-wire single-ended, field-powered, non-isolated, channel-to-channel signals to the swing-arm screw terminals. Field power from the DeltaV AI card is not supported.
