8.5 5704 Gas Card and Catalytic Type Detector Catalytic detectors require a three wire connection and the detector documentation will indicate three connections S, 01 and NS, which are usually brown, white and blue respectively. At the System 57 end of the field cable, the three detector wires should each be connected to the respective matching S, 01 or NS terminal of the appropriate channel on the Quad Relay Interface Card that is attached to the required Four Channel Control Card. NS S 01 19 17 15 Detector NS S 01 5704 Quad Card The diagram shows the detector connections for Channel 1. Channel 2, 3 and 4 connections are similar and their terminal connection numbers are shown in section 7. 8.6 5704 Gas Card and 2 Wire Loop Powered Detectors Loop powered detectors require a two wire connection and the documentation will indicate the positive and negative loop connections, usually brown and blue respectively. At the System 57 end of the field cable the two detector wires should be connected to the S (positive) and 01 (negative) terminals of the appropriate channel on the Quad Relay Interface Card that is attached to the required Four Channel Control Card. 8.6.1 4-20mA loop powered detector (measuring resistor in supply return) 01 - + 28 27 Detector S 5704 Quad Card The diagram shows the detector connections for Channel 1. Channel 2, 3 and 4 connections are similar and their terminal connection numbers are shown in section 7. 12 System 57 Quick Start Guide 05701-M-5026 MAN0839 Issue 1 8.7 5704 Gas Card and 3 Wire 4-20mA Transmitter ctor documentation ould be 4V ote: Terminals 35 and 36 on the Relay Interface Card are input terminals only and cannot he Schematic below details the connections for 3 wire current source transmitters. For . Transmitters require either three or four wire connections and the dete will indicate the 0V and +24V power connections and the positive and negative loop connections. At the System 57 end of the field cable the detector loop signal wires sh connected to the S, 01, NS terminals on the Quad Relay Interface Card that is attached to the required Four Channel Control Card. The exact terminals used vary depending upon whether three or four wire topology is used, the requirement for a loop current source configuration and the channel to be connected to. The transmitter power connection +2 and 0V should be connected to a suitable dc supply. N be used to power the transmitter.
